Putting a tax on carbon could be an effective approach for curbing global warming pollution.
A cap on carbon is important because it sets a specific goal for reducing carbon emissions 80% by 2050.
I do believe that the coal industry sees the cultural shift toward cleaner energy and global warming solutions as a threat to their interests.
As heat rises, so does the number of people trying to cool down homes, schools, hospitals and businesses. This isn't just about comfort; it's a matter of public health.
Too often, the air conditioners we use to cool down also contribute to climate change - the very force that's fueling extreme heat.
Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.
Shell Oil's decision to pull the plug on drilling for oil in the Chukchi Sea is a major victory for the Arctic.
When climate change supercharges weather patterns, the disadvantaged often suffer first and most.
Instead of going to the ends of the Earth - and plumbing the depths of the oceans - to squeeze out every last drop of oil, we need, instead, to do everything we can to reduce the risks of offshore oil and gas production.
Business leaders, social justice groups, farmers and ranchers, doctors and nurses and people from all walks of life are concerned about the climate threat.
Climate change deniers would have us believe that oil, gas, and coal are the only ways to power a modern, industrialized society. They are wrong, and the proof is all around us.
Strong limits on carbon pollution will save Americans money, create jobs, improve our health, and help defuse climate change.
Tar sands oil is the dirtiest fuel on Earth. Because producing it consumes so much energy, a gallon of tar sands crude generates 17 percent more carbon pollution than conventional crude oil.
The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme.
From reinforcing beaches in the Rockaways to installing generators at the Coney Island Houses and sealing holes in the subway system, New York is fortifying our ability to withstand future storm surges.
Green roofs, roadside plantings, porous pavement, and sidewalk gardens have been proven to reduce flooding. They absorb rainwater before it swamps the streets and sewage systems.
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.
We'll always need energy. We need to communicate, too, but we're not stuck with hand gestures and smoke signals. There are better ways to power our future than by digging fossil fuel from the ground and setting it on fire.
The U.S. can become carbon neutral in our lifetimes. In the process, we will put millions of Americans to work, make our companies more competitive, and shield our communities from extreme weather. And we will honor our obligation to leave the world a better place for future generations.
Los Angeles County is one of the most park-poor urban areas in the nation, and the San Gabriel Valley - stretching from Pasadena to Pomona - is especially starved for open space.
