The Demographics Of Disagreement On Climate Change

Brady Carlson — Mon, 15 Apr 2013 22:30:09 +0000

Last week the UNH Survey Center released the latest findings of the Granite State Poll. The Survey Center has been following a number of issues recently, the most high profile of which is whether or not there’s public support in New Hampshire for a proposed casino.

The Survey Center has also been part of a project looking at public attitudes about climate change – namely, why there’s a consensus among scientists – but not the public - that global warming is happening and caused by human activity.

Decarbonizing The Grid: Where Are We?

Sam Evans-Brown — Tue, 29 Jan 2013 20:00:00 +0000

New Hampshire’s energy grid relies heavily on fossil fuels like oil and coal, and getting the grid off of those fuels will be a major hurdle in addressing the challenge of global warming.

But here in New Hampshire, it’s proving a steep challenge to get carbon out of the electric supply, without breaking the bank for customers or utilities. But that doesn’t mean that people aren’t trying. As part of a weeklong look at New Hampshire’s Energy Future, we ask what’s being done about CO2?

Dear EarthTalk: Is it true that cutting and burning trees adds more global warming pollution to the atmosphere than all the cars and trucks in the world combined? -- Mitchell Vale, Houston, TX

Dear EarthTalk: I heard that the Arctic summer sea ice is at its lowest level since we began recording it. What are the implications of all this melting?]

Is It Too Late to Avoid the Worst Impacts of Climate Change?

Dear EarthTalk: I read that CO2 in our atmosphere is now more than 300 parts per million. Doesn’t this mean that we’re too late to avoid the worst impacts of climate change? -- Karl Bren, Richmond, VA

Actually the amount of carbon dioxide (CO2) in the atmosphere today is roughly 390 parts per million (ppm). And that’s not good news.

Shake It Off: Earth's Wobble May Have Ended Ice Age

Christopher Joyce — Thu, 05 Apr 2012 07:35:00 +0000

The last big ice age ended about 11,000 years ago, and not a moment too soon — it made a lot more of the world livable, at least for humans.

But exactly what caused the big thaw isn't clear, and new research suggests that a wobble in the Earth kicked off a complicated process that changed the whole planet.

Ice tells the history of the Earth's climate: Air bubbles in ice reveal what the atmosphere was like and what the temperature was.

Pollution Playing A Major Role In Sea Temperatures

The Atlantic Ocean, especially the North Atlantic, is peculiar: Every few decades, the average temperature of surface water there changes dramatically.

Scientists want to know why that is, especially because these temperature shifts affect the weather. New research suggests that human activity is part of the cause.

Scientists originally thought that maybe some mysterious pattern in deep-ocean currents, such as an invisible hand stirring a giant bathtub, created this temperature see-saw.

And that may be part of it.

Climate Scientist Admits To Lying, Leaking Documents

Christopher Joyce — Wed, 22 Feb 2012 22:01:00 +0000

Peter Gleick is not just any scientist. He got his doctorate at the University of California, Berkeley and won a MacArthur "genius" award. He is also an outspoken proponent of scientific evidence that humans are responsible for climate change.

And earlier this week, he confessed that he had lied to obtain internal documents from the Heartland Institute, a group that questions to what extent climate change is caused by humans.

Gleick's deception has shaken the science community.
