Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.
Alan Lowenthal
As we pump greenhouse gases into our atmosphere, the ocean absorbs carbon dioxide, making the seawater acidic and hostile for shellfish and corals.
Barry Gardiner
Whilst the developed world may say it wants to see much greater commitment to reduce greenhouse gas emissions, this may only be politically feasible if there is strong support for adaptation measures in those countries at greatest immediate risk.
If we are serious about moving toward energy independence in a cost-effective way, we should invest in solar energy. If we are serious about cutting air and water pollution and reducing greenhouse gas emissions, we should invest in solar energy.
Bernie Sanders
For every $1 billion we invest in public transportation, we create 30,000 jobs, save thousands of dollars a year for each commuter, and dramatically cut greenhouse gas emissions.
Since stepping down as laboratory director in 1999, I have devoted an increasing fraction of my time to international issues. I am involved with energy, environment, and sustainability issues, particularly as they involve new energy sources free of greenhouse gases.
Burton Richter
You know what I always dreamed of? That with the greenhouse effect, one day Estonia can be what L.A. is right now. I always thought when the end of the world comes, I want to be in Estonia. I think then I'd survive.
Carmen Kass
With pollution from traffic a major source of greenhouse gas emissions, we should be building a transport and planning system that makes car-free travel for shorter distances the norm for the majority.
Caroline Lucas
On some issues, Republicans and Democrats disagree so sharply that compromise is nearly impossible. Republicans are not going to support a cap-and-trade program to limit greenhouse gases, and Democrats won't support a 1,000-mile wall on the border with Mexico.
Cass Sunstein
Under the Paris agreement, every one of the 147 signatories issues what is called an 'intended nationally determined contribution' (INDC), which amounts to a promise that the nation will take certain actions to reduce greenhouse-gas emissions by a certain date.
Charles C. Mann
There are several types of greenhouse gasses, but carbon dioxide is the most important.
There is an incredible renewable energy resource off both coasts of this country - wind and tidal energy that can power our economy, create good paying jobs and reduce greenhouse gas pollution.
Chellie Pingree
Neglecting clean energy sources such as solar, wind, and especially nuclear, can result in blackouts, increased power bills, and will take a heavy toll on our efforts to reduce greenhouse gases.
Christine Todd Whitman
Burning fossil fuels emits carbon dioxide. And carbon dioxide is a greenhouse gas that traps heat in the atmosphere. There is no debate about that. The link is as certain as the link between smoking and cancer.
The greenhouse effect of carbon-dioxide emissions does produce gentle warming if it is not counteracted by unpredictable natural phenomena, but it cannot be measured directly against the volume of such emissions.
Conrad Black
Reducing and removing greenhouse gas emissions spares our planet from the well-documented degradation that we are witnessing on a global basis.
Dick Durbin
Denmark, the Netherlands and Germany have detailed plans to cut their greenhouse emissions by 20 to 50 percent.
Donella Meadows
Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.
Ed Davey
I'm proud to have led the brokering of the ambitious 2030 climate package in the European Union to cut greenhouse gases by at least 40%, which puts the E.U. ahead of the global pack in terms of commitments.
For myself I hold no preferences among flowers, so long as they are wild, free, spontaneous. Bricks to all greenhouses! Black thumb and cutworm to the potted plant!
Edward Abbey
I stick to stuff I'm pretty sure of and I know this: when the price of a barrel of oil is under $80 a barrel and you build a pipeline, you are driving up greenhouse gases.
The safest way to ship bitumen is by rail. Now, there are other things that you get doing it that way. There's probably more greenhouse gases in shipping it by rail. I think certainly there are.
You could warm Mars up, over time, with greenhouse gases.
I've been vegan for 15 years, and it turns out it makes a very big impact on the environment to eat fewer animal products, which cause more greenhouse gases than all of transportation combined.
There is universal consensus among experts that the earth's atmosphere is heating up - and that we are responsible for it by putting carbon dioxide in the atmosphere. We also know that the consequences of global warming are catastrophic. But how do we make sure that all countries reduce greenhouse gases?
Greenhouse gas production, water usage and environmental issues more broadly are being mitigated by Canadian technological advances more and more each year.
New York and Connecticut belong to the Regional Greenhouse Gas Initiative to cut carbon emissions, and New York City has been a leader in energy efficiency.
Though Africa is not responsible for emitting greenhouse gases, it is suffering the consequences of climate change.
Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans' health and to the environment upon which our economy and security depends.
The EPA's greenhouse gas regulations, along with a host of other onerous regulations, are unnecessarily driving out conventional fuels as part of America's energy mix. The consequences are higher energy prices for families and a contraction of our nation's economic growth.
Climate change is a consequence of the build up of greenhouse gases over the past 200 years in the atmosphere, and virtually all these emissions came from the rich countries.
The simplest way to remove carbon dioxide, the main greenhouse gas, is to grow plants - preferably trees, since they tie up more of the gas in cellulose, meaning it will not return to the air within a season or two. Plants build themselves out of air and water, taking only a tiny fraction of their mass from the soil.
The climate crisis is both the easiest and the hardest issue we have ever faced. The easiest because we know what we must do. We must stop the emissions of greenhouse gases. The hardest because our current economics are still totally dependent on burning fossil fuels, and thereby destroying ecosystems in order to create everlasting economic growth.
We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases.
Solving the climate crisis is the greatest and most complex challenge that homo sapiens have ever faced. The main solution, however, is so simple that even a small child can understand it. We have to stop our emissions of greenhouse gases.
People are unaware of what is going on. When I talk to people, they know the basics, they know the planet is warming because of greenhouse gases... but they don't know the actual consequence of that.
Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.
Growing hemp as nature designed it is vital to our urgent need to reduce greenhouse gases and ensure the survival of our planet.
You see, the Greenhouse Effect is a direct result of burning fossil or old carbon fuels.
Even if we were to stop putting out greenhouse gases right now, we'd still face decades of warming.
Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees.
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution.
I hope that in future Congresses there will reemerge a recognition that climate change is a reality, that our policies to meet our energy needs must also deal responsibly with environmental issues, including the damage caused by greenhouse gas emissions.
When people switch to car-sharing from car ownership, they reduce their vehicle miles traveled by 44 percent, and thus their greenhouse gas emissions go down by, like, 40 percent.
As a California state legislator, I supported our cap-and-trade law to force polluters to pay for releasing harmful greenhouse gases to combat climate change.
There's no debate about the greenhouse effect, just like there's no debate about gravity. If someone throws a piano off the roof, I don't care what Sarah Palin tells you, get out of the way because it's coming down on your head.
Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars, trucks, planes and ships in the world.
Nuclear power can continue to help us reduce our greenhouse gas emissions, but we must do everything we can to make it safer.
Managing forests, rivers, grasslands, and coral reefs in sustainable ways makes them more resilient and increases their ability to absorb greenhouse gases, which is good for business.
