Global Warming and Changing Weather

Why DOESN’T global warming just raise the temperature everywhere a little bit?

The amount of global warming that scientists are predicting doesn’t seem like that big a deal — maybe about 4 degrees Fahrenheit if we control emissions, up to maybe 12 if we don’t.  But as I’ve said a hundred times — and the experts have said a lot more often than that — we won’t …

Could a Riparian Conservation Network increase the ecological resilience of public lands?

A new article suggests river corridors could leverage existing policies to build habitat connectivity

As we try to protect biological diversity for the future, a perpetual challenge is ensuring that the strategies we adopt today will continue to work in the face of changing conditions. How can we design conservation approaches that will be resilient in the face of environmental challenges that will only become more severe in coming years? …

Don’t Know Much ‘Bout Climatology

Why should we believe the scientists about climate change?  Nobody — not even any individual scientist — understand all the details of the IPCC’s recent 1552 page “summary” of climate science.  So why buy into the idea that tiny amounts of gases from beneficial energy production can cause devastating global harm? Part of the reason …

Should Environmental News Coverage Be In The Science Section?

A whiles back I wrote about how the New York Times’ environmental coverage had been in decline. The public editor at the Times has a new article stating that environmental coverage has recently increased substantially. I think that is a great thing. But I want to focus on another element of the public editor’s article. …

Conspiracy!

Even as conspiracy theories go, the

Some members of Congress — not to mention any number of bloggers — think climate change is a hoax.  Most famously, Senator Inhofe has said: With all of the hysteria, all of the fear, all of the phony science, could it be that manmade global warming is the greatest hoax ever perpetrated on the American …

Lies, Damned Lies, and Climate Denial

One key question is whether these statements amounted to factual accusations that Mann had engaged in scientific misconduct.

A D.C. trial judge recently refused to dismiss climate scientist Michael Mann’s libel lawsuits against the National Review and the Competitiveness Institute.  There are some serious constitutional barriers against such libel suits, which are designed to provide ample breathing room for free speech.  Is this one of the rare cases that can jump the hurdles?

Why the Warming Plateau Can’t Disprove Global Warming

The NY TImes has a thoughtful appraisal of the warming plateau — the fact that global temperatures rose until about fifteen years ago and have wobbled around the same level since then.  I think the Times has it about right, but I’d like to point to a less obvious reason why the plateau should not …

How Warm is the Planet? — The Warmest in 5000 Years

A new study in the journal Science shows just how extraordinary our current weather is. Here are the key findings: In one century, we have reversed a five thousand year cooling trend. Global temperatures have gone from nearly the coldest to the warmest in the past five thousand years.  To give some perspective, five thousand years ago was about …

Feeling the Heat

The forecast for the end of this century seems to be getting worse.  New measurements, reported by E&E here, indicate that Greenland is shedding ice rapidly — and Antarctica is also shedding: Ice sheets in Greenland and Antarctica are shrinking three times faster than they were in the 1990s, and their contribution to global sea …

Highly Uncertain But Not in Doubt

It seems paradoxical to say that climate change is uncertain but not in doubt.  At this point, we can be highly confident that greenhouse gases are disrupting the climate system and that the disruption will be very serious unless we act.  But there’s considerable uncertainty about   the magnitude of climate change and its local …
