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.
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.
As we pump greenhouse gases into our atmosphere, the ocean absorbs carbon dioxide, making the seawater acidic and hostile for shellfish and corals.
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.
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.
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.
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.
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.
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.
