Sustainable Building Certification

The next great debate in the building & design industries will not be whether to build green or not – it will be whether or not to build to third-party standards and seek a green building certification.

The advantages of green or sustainable building are both numerable and measurable. Sustainable buildings result in increased productivity. For example, studies published with the US Green Building Council report that

• Students attending green schools produce 20% better test results than their peers in conventional classrooms
• Patient recovery in green health care environments results in improved discharge rates of 2 days or more on average
• Retail sales are higher and worker productivity in offices is reported to increase by 2-16% depending on the green features employees enjoy in their jobs.

Additionally, operating savings for sustainable buildings can be as much as 50%, occupancy rates, as well as rent, are reportedly 3-4% higher. Building owners who choose green methods of construction or renovation are often rewarded by government with fast-track permits, energy rebates and other monetary incentives.

Sustainable design, also called “green” or high performance building, provides economic, human and community benefits as well as reduced environmental impacts.
So pretty soon, we won’t be talking “if” green … the conversation will shift to “how” green.

As sustainable architects here in Sarasota, our firm encourages our clients to build green – all right, we actually design green features into every project whether a client requests them or not because the reality is that it doesn’t cost any “extra” to include basic and practical sustainable building design principles like:

1. Building orientation
2. Natural daylighting
3. Energy-efficient HVAC
4. Low VOC paint
5. Many other examples as well

But as green awareness grows and consumers become savvier with their green purchases, the value of third-party certification will help building owners and tenants distinguish the authentically sustainable design offerings from those offering green lip service.  

In 2007, we purchased a 1930s era grocery store in downtown Sarasota for the purpose of renovating it to LEED Commercial Interior (CI) standards to become our firm’s new headquarters.  We divided the 4,400-square-foot building and occupy 2,400 square feet.  Our renovation costs were roughly $85 per square foot.  Our sustainability features included:

• Double-pane thermal windows and doors
• Added insulation
• Energy star rated reflective roof system
• Energy efficient HVAC
• Low energy fluorescent lighting
• Low flow plumbing fixtures 

We consciously made the choice to seek LEED certification for the project – over and above the fact that our building decisions met the criteria – for two reasons.  If we are going to encourage our clients to seek certification, we should walk the walk.  And we recognize the investment payoff that third-party certification represents.  We chose the LEED system, over other available systems, because LEED standards are rigorous.  Anyone can say they built green, but everyone knows that if LEED says it’s green, it’s certifiable.

Our commissioning fees and extra costs for construction measures we chose were $8,900 including our USGBC membership based rate of applying for certification.  (The USGBC lists fixed rates for certification fees ranging between $1,250 and $22,500, depending on square footage and USGBC membership status). This added a $3.71 cost per square foot to our renovation, approximately 4% to the budget, but we have seen our investment pay off through marketing and branding exposure as well as real property appreciation.  

Other certification systems may be cheaper and easier, but because they don’t have the brand power of LEED, some detractors say they offer a less verifiable way of certifying the green-ness of a sustainable building project.  But these other systems, including the National Association of Home Builders’ new program, Energy Star, Florida Green Building Coalition and the newest arrival, Green Globes, are generating increased buzz about how green to go.  Meanwhile the common denominator is a shared desire to validate sustainable building design.

Our industry is transforming itself not only because the health of the planet is at stake, but because there is sufficient momentum and incentive to move in this direction.  Regardless of which certification method is selected, green standards are here to stay.

If you are considering a green building project, we understand that research is a major, primary component. We would like to encourage this process and offer our experience and expertise. If you have questions and would like a second opinion, feel welcome to contact us for a productive discussion.

We have recently found some great ways to measure a LEED Projects distance a manufacture's location.

The first, http://www.freemaptools.com/radius-around-point.htm lets you produce a map based on your project's location, you can customize the distance so you could also use it for the Density & Development 1/4 mile credit.You can also export the radius to Google Earth!

Second, http://indo.com/distance/ will tell you the distance between 2 cities as a bird flies, ie Sarasota, FL & Birmingham, AL.

The following article was written by an award winning, experienced, LEED accredited, green building architect based on the Gulf Coast of Florida. The purpose of this post is to educate readers on the facts about:

Climate Change And Reducing Carbon Dioxide Pollution

We are not doing enough, and we are not doing it fast enough. 

The climate of the planet is changing, and we are mostly responsible for the changes that are occurring, at least since around 1750. As a species, we can measure the carbon dioxide (CO2) in our atmosphere. Right now we are at about 400 ppm (parts per million) of CO2. We also have ways to measure CO2 levels in our atmosphere in the past. I often hear about the idea that CO2 in our atmosphere has always fluctuated up and down naturally, so there is nothing to worry about. 

It is true that there have been natural fluctuations in the levels of CO2 in Earth’s atmosphere. For about the past 400,000 years, CO2 has been fluctuating from about 180 ppm to about 280 ppm.  But something is different, and we can see it. Since the start of the industrial revolution in the late 1700’s, the graphs charting CO2 levels have not turned downward. In fact, they have shot through the roof. For the past 20,000 years they have been climbing from 180 ppm to the 400 ppm that we are at now. The climb from 180 ppm to 280 ppm took about 19,000+ years (perfectly within the predictable fluctuations of 400 millennium), the climb from 280-400 ppm has happened in less than 200 years.

Are we surprised that CO2 levels climbed since the dawn of the industrial revolution? Is the world a little different than we were when the United States came in to existence? Though Americans make up just 4% of the world's population, we produce 25 percent of the carbon dioxide pollution from fossil-fuel burning, (by far the largest share of any country). We need to take responsibility for that. We also need to take responsibility for the fact that we are leaders on this planet, and developing countries look to be like us. There are those who would make this a political issue. Don’t let them. It is about science. It is about people who care about each other. The planet will be fine. We will choose to reduce our greenhouse gas emissions, or the planet will force us to do so.

We need CO2 levels to be at 350 ppm, and the current levels are going to go up before we see our good actions then start to bring them down. There is momentum in the natural systems. There are many things we can do. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution. Automobiles are the second largest source. Buildings are responsible for about 39% of CO2 emissions in the US. (directly related to their use of energy, created at power plants). Buildings that use less energy create less CO2 emissions.  Our new and existing buildings need to become more efficient. In buildings, conservation is first: Green building techniques like efficient air conditioning equipment and appliances, good windows, passive low tech stuff like porches, overhangs, insulation and caulking. Technology can help: Solar heat for hot water and using electrical energy from the sun. Find out what you can do at your house at www.greenhomeguide.org/. Get involved in the local US Green Building Council Chapter at www.sustainabletampabay.org. Buildings need to use 50-70% less energy than the codes allows right now, not 20 years from now.

How To Save Money & Make Your Business More Energy Efficient:

On April 17, 2009, after a thorough scientific review ordered by the U.S. Supreme Court in 2007, the Environmental Protection Agency issued a proposed finding that greenhouse gases contribute to air pollution that may endanger public health or welfare.

Locally, Sarasota County Government has signed the 2030 Challenge for carbon neutrality by the year 2030 www.architecture2030.org. The City of Sarasota has signed the U.S. Mayors Climate Protection Agreement, promising to “to enact policies and programs to meet or beat the target of reducing global warming pollution levels to 7 percent below 1990 levels by 2012” and “to meet or exceed Kyoto Protocol targets”. These are targets that require real change. Change we have not yet seen be implemented. While they are currently voluntary, they should not be considered optional. Why should we care? Take a look on the 2030 Challenge web site and see what 1.25 meters (49”) of sea rise will make Sarasota’s Coast line look like, and start looking for that future “waterfront” property.

Part 2 Of Designing & Building A LEED Home

This is the second installment detailing the new LEED certified house we are currently designing.

This particular LEED certified home is on a small lake in Southwest Michigan. The lake sits to the NW, so the primary views are to the NW.  The lot itself is rotated 35 degrees west of due south.  This LEED home wants to use good passive design features and roof mounted solar thermal and solar PV systems. The key passive LEED design feature is to rotate the main roof plan 20 degrees to the south, so that the main roof is only 15 degrees from due south facing. This passive feature helps to block the summer sun, but lets the winter sun penetrate deep into the home for passive solar heat gain and is a critical element of this specific LEED architecture. The main roof also provide a great place to put all the active systems (the PV and solar thermal).  See the roof plan below.  The darker roof area slope is 15 degrees from south.  This passive design feature, while being a key component to the energy conservation strategy, also creates a dynamic and interesting aesthetic feature of the home.

Further to the energy conservation considerations, LEED architecture calls for the selection of the heating and cooling systems that are currently underway.  The heating load exceeds the cooling load in this region, but we need to appropriately address both needs.  Heating is the main focus, but active cooling will be required in the warmest and most humid summer months.  The first thing we did was to create a high performance building envelope.  The wall will be Insulated Concrete Forms (ICFs), the attics will be well insulated, and we will use good quality, double glazed (insulated) windows and doors throughout, another effective element of good LEED architecture. Once the building envelope is determined, the heating and cooling systems can be properly sized. One other interesting consideration that is contributing to this effective LEED architecture is there is natural gas available at the site.  And there will be many times during the year that the home will be naturally ventilated. 

So we are looking at several good LEED architecture systems, keeping in mind energy efficiency, indoor environmental quality, first cost, and life cycle cost. A geo-thermal system is an option. We can get our heating and cooling from this type of system. It would be a force air distribution system - pretty standard air handlers and ducted distribution. Another option is to use a liquid base radiant flooring system.  This provides and amazingly comfortable heat source.  We could use solar thermal panels on the roof to supplement the mechanical heating systems (preheat the liquid on the roof and then refine the actual temperature with a gas or electric system). This can be interconnect (via a heat exchanger) with the domestic hot water system to preheat the domestic hot water system as well.  With the radiant flooring system, we will need to implement a cooling system as well. This may need to be a force air distribution system, which would be a separate system from the heating system. A more conventional heat pump to provide both heating and cooling, and distributed by a force air distribution system is also an option. We will see how all these LEED architecture options play out.

We will also put solar PV panels on the roof to create as much electricity as we can afford.  We will be evaluating the available roof areas for the proper balance of solar thermal and solar PV panels.  Part of that analysis will be about how much (if any) natural gas we want to use, versus going with all electric systems.  Stay tuned as we will be posting updates on this LEED certified home project as we make decisions and execute what we determine represents the best possible LEED architecture components.

If you are starting to research a LEED project and would like some professional advice to get you started in the right direction, feel welcome to contact us for a consultation. Just use the button below to make a request:

Designing & Building A LEED Certified Home

What you should know when considering the construction of a LEED Certified or green home.

We are (as a Sarasota Fl architect) in the process of designing our second LEED certified home now.  I wanted to share some of the process, decision making and what to expect.  Our first LEED certified home was for the HGTV television show in 2009, and was the HGTV Green Home for that year.  It was Platinum level certified.  Our current project in the design development phase now, is located in Southwestern Michigan, and is a new home for my parents.  I will tell you more about the project later, but let's talk a little about the process first.  There is a lot to think about, but don't get overwhelmed. As a trailblazer in LEED architecture in Florida, we truly understand the demands.

First, assemble your team.  Select a sustainable design experienced architect that has already done LEED certified projects, and who has long term commitment to sustainable design solutions.  Green Design should be in the architects DNA, not a segment of their practice.  LEED has been around for about 15 years now, and well within the main stream for 6-8 years now, so if your architecture design team has not been engaged, what could they be waiting for?  Many architects can talk the LEED certification talk now, but can they (and have they) back up the talk by walking the walk.  The architect designing your house should be a LEED accredited professional. (LEED AP)

Get some help with the design of the mechanical systems including the cooling and heating systems.  In most jurisdictions you are not required to have a licensed mechanical engineer involved in your single-family residential project.  This design work is typically left up to the subcontractors to figure out the details of the design. In a high-performance building it is important to have expertise available to design the systems.  Don't leave it up to the subcontractor to do the system he is most familiar with. You want your design team to look at systems that far exceed the code minimum requirements.

Bring your general contractor on board as soon as your design team has a concept design established.  Designing a high performance home requires an integrated design and construction team working together to optimize the outcomes.  The general contractor can provide valuable knowledge on construction techniques suitable for your area and climate zone.  The GC can provide preliminary cost estimating during each phase of the development of the design to make sure your project stays on budget.  The GC can bring in their subcontractors into the discussion to provide input into the selection of building systems to be used on your project.  I suggest getting several references for good experienced general contractors and then narrowing that list down to two or three contractors that you would like to interview in person.  Don't base your decision strictly on price. Remember that you are in the early design stage of the project at this point and many of the details and systems have not yet been established.  A hard bid at this phase is not possible.  Look more at qualifications, past experience and how the general contractor calculates his fee. And the general contractor should have LEED accredited professionals on staff. 

One side thought: I think it is best as the owner to hire the design team and construction team under separate contracts.  The design/build delivery method is less successful. Having the design team subservient to the contractor lends itself to mediocrity and reduces accountability.  

Remember-Bring your contractor on board early!

To seek and obtain LEED certification for your home you will need a LEED provider. You can connect with your lead provider using the USGBC website to find the lead provider in your area.  Sometimes there's more than one in your area. The LEED provider will coordinate with you and your contractor everything that you need to do to seek LEED certification.  They can be a valuable resource.  They understand the process and they have many connections in their community from other LEED projects they have worked on.  You will also need a LEED Rater for your project. Your LEED provider can connect you with Raters in your area.    The greater will visit your job site and do inspections and report back the results as part of the certification process. They will also do the preliminary HERS score evaluation and do the blower door test to establish the actual HERS rating at the end of construction.  The Rater will assist your GC in helping with quality control on the job site. 

Use the LEED for Homes checklist of points as your guide through the project. Have a copy of the LEED for Homes reference guide handy for used by all the team members.

Depending on the specifics of your project you may need some additional design consultants at your discretion.  You may need interior design services, landscape architecture, acoustical engineering, geotechnical engineering etc. 

Now you have your core team together. Work together to design a fantastic Sustainable home!

US/China Climate Change Deal: Environmental Planning?

I read with interest today the news about the China/USA agreement to curb carbon emissions in hopes of reducing climate change and supporting more sustainable environment.  I was excited.  It is always good to read about any country willing to voluntarily reduce its carbon emissions. 

Then I read the details.

So the US is going to curb its emissions by 26% to 28% in 2025, down from its 2005 levels.  What happened to the 2030 challenge?  At this rate, will we achieve carbon neutrality by 2100? Or never?  Not until the last drop of oil and last lump of coal is burned into the atmosphere I guess.  Setting goals so low is really discouraging.  The science does not support such limited action.  And of course the political forces that benefit from a fossil fuel based economy are already lining up to kill even this small initiative.  I heard them use the term “war on coal” again today.   Sort of like when the Federal government (U.S. Department of Health and Human Services) and organizations like the American Cancer Society started the “war on Cancer” (1971) and big business and parts of the government supported the tobacco industry as it hooked us in and killed us off as fast as it could?   Reducing carbon emissions won’t hurt the economy.  Business as usual will.

And China is going to “stop its emissions from growing” by 2030.  Really?  So China is planning to increase its emissions every year for the next 16 years before it starts reducing them?  How is that a reduction?  China completes a new coal burning electrical plant every 8-10 days.  And their policy of unlimited growth is not sustainable.  The planet simply can’t take it.  One positive component of the agreement is that China will be introducing more “non-fossil fuel” energy sources into its production.  But they include Nuclear in that category, along with renewables.  Luckily economic growth in China is slowing. 

Many Countries in Europe, Great Britain and Scandinavia have much more aggressive goals.  They are out ahead of climate change and their economies and citizens are benefiting from that.  Sweden has a goal to be carbon neutral by 2016!  Housing in Britain will need to be net zero energy in the same time frame.  Even here in the US, solar power is now cost neutral compared with fossil fuel base electric from the utility monopolies.  And it is projected that solar power will cost neutral in 47 states by 2016. 

So it seems business (mostly) as usual is still the plan of action for decades if not a century to come.  Luckily, complex systems, such as the ecological system of the planet can self-regulate and adapt.  If it needs to, it will disrupt the economy, and eventually the human population.  (It already has.  Most of us are just in an economic position to insulate ourselves from the suffering so far) Its complex, interrelated systems will adapt and adjust, and change as needed.  Those adjustments won’t care about what happens to humans on the planet.   

So as I said in a previous blog: (from the Katherine Hayhoe presentation on 10/22/2014, at the USGBC GreenBuild Conference in New Orleans)

We are facing 3 choices when it comes to climate change

1. Mitigate - reduce emissions

2. Adapt- to the changes (our current infrastructure cannot cope with changes to our climate)

3. Suffer- some suffering is inevitable, how much is our choice

So far it looks like we (the US and China, who account for 45% of the world’s greenhouse gas emissions) will take a gentle, easy, slow road on 1 and 2.   Is option 3 going to be the “winning” strategy?  Is that really what our leaders want?  I truly hope not.  Can we adapt and change without a full blown climate crisis?  It does not look good.

Here is a helpful checklist that will help you do your part.

More Information On Solar Energy Planning & Costs!

It seems that everyone these days is a “green building expert”.  Many have recognized the “trend” is not going away, and those who were once resistant have recently opted to jump on board.

Carlson Studio committed to LEED green building design in 2000. As an early adaptor, we have grown up with the LEED system over the years. Sustainability is a key principal that we apply to all of our projects. We also provide eco-consulting to assist architects, contractors, owners and other design professionals in the process of designing sustainable buildings.

But when hiring any expert for green building design or eco-consulting, it can be difficult to know whether you’ve encountered a true green professional, or one who simply dabbles in the concepts of sustainability in order to keep up with trends. One critical determining factor is to fist learn whether a designer, builder, architect or any other contractors are LEED Accredited, and  has  LEED Certified projects on their list of references.

What is LEED?

LEED (Leadership in Energy and Environmental Design) is a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes and neighborhoods. It was developed by the U.S. Green Building Council (USGBC) for the purpose of helping building owners and operators be environmentally responsible and use resources efficiently.

There are 5 categories corresponding to the specialties available under the LEED Accredited Professional program:

• Building Design and Construction
• Interior Design and Construction
• Building Operations and Maintenance
• Neighborhood Development
• Homes

What is a LEED Accredited Professional?

The LEED Professional Credentials were developed to encourage green building professionals to maintain and advance their knowledge and expertise. A LEED Professional Credential provides employers, policymakers and other stakeholders with assurances of an individual’s current level of competence and is the mark of the most qualified, educated and influential green building professionals in the marketplace.

There are three tiers in the LEED Professional Credentialing program:

• Tier 1: LEED Green Associate - denotes basic knowledge of green design, construction, and operations.
  
  
• Tier 2: LEED AP with specialty - signifies an advanced depth of knowledge in green building practices; it also reflects the ability to specialize in a particular LEED Rating System.
  
  
• Tier 3: LEED Fellow - highly accomplished class of individuals nominated by their peers and distinguished by a minimum of 10 or more years of professional green building experience.

What is LEED Certification?

There are four levels of certification - the number of points a project earns determines the level of LEED certification that the project will receive. LEED-Certified is the minimum award for recognized green homes. Typical certification thresholds are:

• Certified: 40-49 points
• Silver: 50-59 points
• Gold: 60-79 points
• Platinum: 80+ points

When you’re ready to go green, either as part of a new building project, or renovation of an existing building, remember to check for the all-important criteria above, to ensure that your “green experts” really are the experts!

My afternoon session at the 2014 Greenbuild International Conference and Expo today was amazing. Deepak Chopra spoke as part of the master Speaker Series.  I have seen his specials on PBS and read some his books. He is a wise man - and funny.

I cannot present the information he gave us today as eloquently as he did, but here are some points from his presentation:

There are 2 big (hard) questions in science:

1. What is the stuff of the universe? 

• 70% is dark energy
• 25% dark matter (not atoms); there is no way to interact with it, it bends space/time like gravity
• 5% atoms  
• 99+% is invisible stellar dust
• .01% is knowable, visible universe
• sub-atomic particles disappear into waves when not being observed

So, we understand less than 1% of the universe we live in.

2. What is biological basis of consciousness?

It is impossible to model how thought is produced; after all, how can one see a 3-D world in space and time?

Nature of our Reality = SIFT: Sensations Images Feelings Thoughts

The Hard Problem

There is no explanation for how we understand anything. Start with consciousness, and the spiritual, mental, physical world...

• 90% of the body is bacteria - we are a few human cells hanging onto bacteria - WOW.
• Genes are controlled by consciousness; genes do not work on their own, but in networks. You are not your genes; we are much more than that.
• 64% of our genes are same as a banana
• 94% of our genes same as chimp

Deepak Chopra explored additionally fascinating concepts such as:

Ayurveda: the science of life

• meditation
• balance
• diet
• intellect
• senses
• detox
• massage
• yoga therapies

Self-Directed Biological Transformation

• The body is a process, not structure
• Our body is a verb, not a noun
• The body as energy and information
• We can change your relationship with time - in the present, in the moment

The session closed with Deepak Chopra leading the entire audience in 12 minutes of meditation.

After this session, I reflected back on all the Greenbuilds I have attended, since 2002 in Austin TX. This is my 13th in a row. There have been some amazing moments/speakers throughout those years - a few that immediately come to mind:

• David Suzuki
• Bob Berkebile
• Desmond Tutu
• Bill Clinton
• Van Jones
• E.O Wilson,
• Janine Benyus
• and now, Deepak Chopra

All of the above stand out to me as visionary thought leaders who inspire me to raise my game to the next level.

Who inspires you?

More from the Greenbuild International Conference and Expo at the Morial Convention Center in New Orleans, with news and updates on important topics from the event, (day 2)...

My first session today was very interesting. It was titled:

How to score Platinum in LEED - Energy Efficient projects in Sweden

Sweden is doing great things in the realm of energy efficiency, with a goal of all buildings being at nearly zero energy by the year 2020.

BBR Swedish Building Code

New builds and renovations/extensions are subject to the rules set out in the National Board of Housing, Building and Planning's building code, BBR. It sets out a number of requirements with which the finished building must comply. The party erecting the building, usually the property owner, is responsible for ensuring compliance with the provisions. The Planning Department in the relevant municipality shall also ensure that there is compliance. (ref: www.paroc.se)

The BBR Swedish Building Code places restrictions on energy performance for buildings heated with electricity - with fixed limits on energy use and more stringent performance requirements. There are no specific details in the code on how to accomplish these goals, which are different from ASHRAE standards in the USA.

Requirements are set with the effect of ensuring that mandatory energy calculations are performed at the planning stage and that energy performance is verified by measurements within 24 months of building completion. This is a major change from the previous codes.

Currently 90% of Swedish LEED buildings score LEED gold or better, (compared to 44% in the United States), with 25% scoring LEED Platinum, (4% in the United States.)

To date, two of the top ten greenest cities in the world are in Sweden. Here are the top 10 ways to score well in Sweden in energy efficiency:

1. set goals: energy efficiency, LEED certification levels, such as platinum
2. get all participating parties involved
3. follow up on goals through design, construction and occupancy
4. well insulated envelope
5. air tight construction - several tests
6. heat recovery in ventilation system
7. energy efficient equipment
8. renewable energy
9. automation and monitoring
10. commissioning and M&V

These are not earth-shattering ideas, but the fact that they do these things as standard practice is what makes the difference.

Key takeaways from today's Greenbuild session:

When Sweden was faced with the fossil fuel energy crisis in the early 1970's, they shifted their energy sources away from fossil fuels, and changed / improved their efficiency in energy use countrywide.

What was the USA response to and since the energy crisis in the early 1970's?

Are we 30-40 years behind where we could have been?

Coming to you from the Greenbuild International Conference and Expo at the Morial Convention Center in New Orleans, with news and updates on happenings and important topics from the event...

My first session today was Marketing and Sustainability: The tools + tips to tell your story.

This was an interesting session with presenters from Herman Miller. Gabe Wing, Herman Miller representative, spoke about storytelling, and HM's Earthright Strategy:

• transparency
• collaboration
• resource responsibility
• community driven

The idea being to "make a living or make a difference". Find your bee story - Look it up on the Herman Miller web site.

My late morning session was on Climate Change. This was part of the Master Speaker Series, with Katherine Hayhoe as the presenter. She is a scientist at Texas Tech, and involved in the ATMOS Research. 

To pull out the bullet points of her presentation:

• Climate Change - it's the biggest health risk of the century
  
  
• It is the story of Energy Industrial revolution: coal, natural gas and oil
  
  
• 41% of US energy use is by buildings
  
  
• Energy use has increased by 400% since the 50's in the United States
  
  
• The invisible problem: invisible heat-trapping gases - Carbon Dioxide
  
  
• The United States has produced 30% of greenhouse gases over past 30 years. This is a higher level of GHG production than that of any other country.
  
  
• For the past 8,000 years of Earth's history, CO2 levels have varied from 180-300 in their historical ranges. In 2014, CO2 levels are now at 400 ppm.
  
  
• Our planet has seen a 43% increase in greenhouse gases since the industrial revolution
  
  
• The data shows a 30-year trend that is clearly warming
  
  
• Ice Age causes: changes in the earths orbit, tilt of axis wobbles and over long periods of time (1000's of years) the earth does gradually cool or warm.
  
  
• Temperature was trending down over last 6000 years, indicating a cooling cycle, until the industrial revolution. Now, temperatures are clearly and abnormally at higher degrees. 
  
  
• Natural cycles move heat around the planet, but they do not heat or cool the planet over all. It is a transferring system; up one place, down another place. (Like El Nino)
  
  
• Oceans have absorbed a lot of the heat, more than the land.

Science shows that more than 100% of our planet's warming is caused by humans. The sun is in a cooler natural cycle, and axis wobble is in a cooling cycle, yet the long term trend since the beginning of the industrial revolution (the large extraction and burning of fossil fuels) shows greater warming, overcoming all the natural cooling trends and more, into a greater warming trend than is natural.

We are facing 3 choices when it comes to climate change

1. mitigate - reduce emissions
   
   
2. adapt - to the changes (our current infrastructure can not cope with changes to our climate)
