Why has Earth’s climate remained so stable over geological time? The answer just might rock you. Rocks, particularly the types created by volcanic activity, play a critical role in keeping Earth’s long-term climate stable and cycling carbon dioxide between land, oceans and the atmosphere. Weathering of rocks like these basalt formations in Idaho triggers chemical processes […]

Economic shutdown reduced carbon emissions, but not enough to keep last month from being the hottest May ever: As reports keep telling us, the worldwide economic response to the coronavirus pandemic has reduced carbon emissions, with as much as 8 percent less CO2 being pumped into the atmosphere compared with 2019. By Meteor Blades But this is temporary. And […]
Living things need carbon dioxide to grow and we, humans, are constantly breathing it out. It can’t really be a pollutant…can it? Find out on this Global Weirding episode. By Katherine Hayhoe Global Weirding Since the dawn of the industrial age, humans have been pumping increasing amounts of carbon dioxide into the atmosphere by burning […]
Most of us learned about photosynthesis when we were in high school. Plants use carbon dioxide and sunlight to make the food they need to grow. That means higher carbon dioxide levels should be good for plants, right? Absolutely, says Republican Congressman Lamar Smith of Texas. He is a firmly committed climate change denier who […]
The carbon tax is one method economists support for putting price on atmospheric carbon, and thereby lowering emissions.
BY Bill McKibben, Philip Radford, Rebecca Tarbotton (Cross-posted from Grist) Dear Friends, God, what a summer. Federal scientists have concluded that we’ve just come through the warmest six months, the warmest year, and the warmest decade in human history. Nineteen nations have set new all-time temperature records; the mercury in Pakistan reached 129 degrees, the […]
The EPA has found, based on the scientific evidence (everyone from academics to strategic planners at the Pentagon agrees on this), that CO2 output is hazardous and needs to be regulated. Senator Murkowski wants to strip the EPA of authority to do that, saying it’s SOOO important that Congress needs to handle it. But is that really what’s going on? We take a look at the reality behind the hype.
Last week I wrote in this space that when faced with a problem that so clearly requires huge top-down action from governments the world over, what two contrarians write in a book doesn’t exactly bother me that much. But now members of Congress are pissed off too.
Today is 350.org’s International Day of Climate Action, during which people around the world are trying to call attention to our need to bring the levels of carbon dioxide in the atmosphere back down to 350 parts-per-million (ppm). A noble cause, to be sure — but can we actually do it?
An archive of my Big Coal cartoons. The pen is mightier than the sword (but probably not as mighty as the multi-billion dollar coal industry…).
According to CO2isgreen.org (and .com and .net) all of this extra carbon pollution we are spewing is good for both us and the Earth! What luck! I’m getting a Hummer!
The Department of Energy (DOE) announced today it will fund $27.6 million for next generation carbon capture methods using geologic storage. Suspiciously, this announcement follows on the heals of the State Department’s approval of a pipeline from Canada’s tar sands to the United States.
Environmental protestors chained themselves to a conveyor belt, protesting that environmental legislation neglected the needs of local wildlife but a spokesman for the plant said ‘… It didn’t affect us in any way and we just left them there until they decided that they felt like going home and they did. These days it’s as much about the show as it is about the reasons, so I guess the show must go on and sometimes the reasons are worthwhile and sometimes they are not.’
a broad coalition of consumer, economic and environmental advocacy groups has published a report on the substantial consumer savings that stronger energy efficiency and renewable energy standards would bring.
An ocean acidification lawsuit filed Thursday in the state of Washington is the first of its kind.
