A meter of sea level rise by 2100? Sea levels may rise much faster and higher than predicted	Joseph Romm	21 Aug 2007	Gristmill
Popular Science has published a terrific article, 'Konrad Steffen: The Global Warming Prophet,' about one of the world's leading climatologists. Steffen has spent '18 consecutive springs on the Greenland ice cap, personally building and installing the weather stations that help the world's scientists understand what's happening up there.' The article notes: Water from the melting ice sheet is gushing into the North Atlantic much faster than scientists had previousl ...

A very good article on 'tipping points' And at what temperature Greenland's ice sheet will melt	Joseph Romm	18 Aug 2007	Gristmill
Climate tipping points have been the subject of much debate and confusion. Now Professor Tim Lenton of the University of East Anglia has published a very good piece, 'Tipping points in the Earth System,' giving some intellectual substance to the notion. Not surprisingly, the tipping point Prof. Lenton worries about most is the disintegration of Greenland's ice sheet. He told The Guardian: We know that ice sheets in the last ice age collapsed faster than any cur ...

Sorry, Grandchildren Climate tipping points could happen sooner than expected, says research		17 Aug 2007	Daily Grist
Sorry, Grandchildren Climate tipping points could happen sooner than expected, says research You thought the predictions of climate chaos by the Intergovernmental Panel on Climate Change were scary? You ain't seen nothin' yet. The IPCC predicted that the massive Greenland ice sheet could completely melt in 1,000 years, raising sea levels by almost 23 feet. But in a new study, British researcher Tim L ...

Climate forecast: Hot, and then very hot In nontechnical terms	Joseph Romm	16 Aug 2007	Gristmill
For those wondering why the planet hasn't yet exceeded the 1998 El Niño-fueled temperature record, a new Science magazine article ($ub. req'd) explains why. Basically, in addition to the steady increase in anthropogenic warming from greenhouse gases, you have to add a smaller variation from climate oscillations linked to the oceans. Those oscillations have been tamping down temperatures a tad, and will keep doing so for the next couple of years, but the decade of th ...

Freeman Dyson, climate crackpot Yet another one	Joseph Romm	16 Aug 2007	Gristmill
As a physicist, I have never been a big fan of Freeman Dyson. He was, after all, one of the 'geniuses' pushing Project Orion -- the absurdly impractical idea of creating a rocket ship powered by detonating nuclear bombs -- I kid you not! Dyson has written a new book, A Many Colored Glass, that you shouldn't waste your time and money on -- as this extract on global warming makes clear. Dyson has basically joined the famous-crackpot camp with Michael Crichton and ...

Dust to Dust NASA recalculates, 1998 becomes second-hottest year in U.S.		16 Aug 2007	Daily Grist
Dust to Dust NASA recalculates, 1998 becomes second-hottest year in U.S. The year 1998 has dropped from the hottest-year-ever-in-the-U.S. throne after NASA revised calculations, allowing Dust-Bowl-affected 1934 to claim the title. Despite triumphant cackling from climate skeptics, the rejiggering does not affect global climate records, and really is, for all intents and purposes, a technicality -- gl ...

Unspun climate numbers Move over, 1998	Sean Casten	15 Aug 2007	Gristmill
Turns out that in the U.S., 1934 was a bit hotter than 1998. Which matters not a whit for global temperatures, but it's worth reading the story below before the spin machine gears up. Mr. Limbaugh has already started. '1934, not 1998, the hottest year on record, NASA confirms,' from Greenwire ($ub req'd): The hottest year on record in the United States was 1934 -- not 1998 as had long been believed -- NASA scientists announced this week. The change to the record b ...

Shrinky-Dinky Do Great Lakes, Arctic sea ice shrinking to record lows		14 Aug 2007	Daily Grist
Shrinky-Dinky Do Great Lakes, Arctic sea ice shrinking to record lows It could be a summer of record lows in two of the world's iconic places: the Great Lakes and the Arctic seas. Water levels in Lakes Huron, Michigan, and Superior are well below normal, and Superior could soon hit a record low set in 1926. The U.S. and Canada have undertaken a five-year study that c ...

Must-read from RealClimate The latest skepticism, debunked	Joseph Romm	13 Aug 2007	Gristmill
Not that anyone but a denier or two believed that some microscopic revision in a few years of temperature data meant the theory of human-caused global warming was even slightly undercut -- but progressives need to know all the rebuttals. I emailed Gavin Schmidt at RealClimate about this -- I'm sure I wasn't alone -- and he put together a very nice debunking post. As Gavin writes, 'there is clearly a latent and deeply felt wish in some sectors for the whole problem of ...

Their Bark Is Worse For Our Blight Decade-long study says trees may not be good at offsetting carbon		10 Aug 2007	Daily Grist
Their Bark Is Worse For Our Blight Decade-long study says trees may not be good at offsetting carbon Step away from the vegetation, treehuggers, and find something else to embrace. New research finds that when it comes to offsetting greenhouse gases, trees may not be up to the challenge. For 10 years, Duke University researchers plied a stand of North Carolina loblolly pines with ...

Hurricane update They might be coming sooner than you think	Andrew Dessler	01 Aug 2007	Gristmill
From a NASA's Earth Observatory: Hurricanes need two basic ingredients to develop: warm, moist air and a relatively calm atmosphere. Late summer over the Atlantic Ocean provides both things. Ocean waters above about 27 degrees Celsius (80 Fahrenheit) give rise to the warm, moist air that fuels tropical storms, and winds that could tear a storm apart are light during the summer. Typically, the Atlantic is primed for hurricanes by early August, and the height of the ...

Climate change Game over	Andrew Dessler	27 Jul 2007	Gristmill
In an editorial in this week's Science Magazine, Donald Kennedy writes: With respect to climate change, we have abruptly passed the tipping point in what until recently has been a tense political controversy. Why? Industry leaders, nongovernmental organizations, Al Gore, and public attention have all played a role. At the core, however, it's about the relentless progress of science. As data accumulate, denialists retreat to the safety of the Wall Street Journal op- ...

Storm World: Understanding hurricanes today New book on hurricanes and global warming	Kit Stolz	16 Jul 2007	Gristmill
On his site, science writer Chris Mooney recently posted a fascinating pair of graphs, courtesy of collaborator Matt Nisbet, which chart public interest in global warming. As the years march by, the charts show what happens when scientific reports are released, when politics intervene -- and when hurricanes strike, as measured by coverage at the Washington Post and the New York Times. What the graphs show is that in these thoughtful newspapers, political and sci ...

Surgeon General and global warming It's as bad as we thought	Joseph Romm	13 Jul 2007	Gristmill
Don't miss this tidbit from Former Surgeon General Richard H. Carmona's Tuesday testimony before Congress: He described attending a meeting of top officials in which the subject of global warming was discussed. The officials concluded that global warming was a liberal cause and dismissed it, he said.'And I said to myself, 'I realize why I've been invited. They want me to discuss the science because they obviously don't understand the science,'' he said. 'I was never i ...

Behind the facade of the Planktos 'Voyage of Recovery' A guest essay from Greenpeace scientists	David Roberts	12 Jul 2007	Gristmill
A while back, after some criticisms of his company on this site, I ran an essay by Russ George, CEO of Planktos, defending his work. What follows is a response to that essay from the UK-based Greenpeace Science Unit. ----- Russ George, CEO of self-professed 'ecorestoration' company Planktos, seems increasingly convinced that opposition to his plans for commercial-scale fertilisation of the oceans with iron results from the activities of 'fringe environment ...

A few random climate thoughts Climate skeptics lose even more credibility	Andrew Dessler	11 Jul 2007	Gristmill
The first half of 2007 is the warmest Jan-June period on record, +0.79°C above the long-term average (from NASA GISS data, via QuarkSoup.net). For those who question the consensus on climate change, see the collection of proconsensus statements at Logical Science (hat tip: Michael Tobis). Just recently, my department (the Dept. of Atmospheric Sciences at Texas A&M University) unanimously adopted a statement endorsing the primary conclusions of the IPCC reports. ...

It's Not the Sun Sun is not causing current global warming, researchers confirm		11 Jul 2007	Daily Grist
It's Not the Sun Sun is not causing current global warming, researchers confirm Attention all ye who think the sun might be a primary cause of climate change, and all ye who know someone who thinks that: No. It's not the sun. Researchers have published a study of the last century of solar activity, finding that the sun's output has actually declined over the last 20 years. (And yes, they did brain ...

The first rule of carbon offsets: No trees A good reason we shouldn't love trees, at least not in this case	Joseph Romm	02 Jul 2007	Gristmill
Everybody loves trees. They are so popular as offsets they even make Wikipedia's definition: When one is unable or unwilling to reduce one's own emissions, Carbon offset is the act of reducing ('offsetting') greenhouse gas emissions elsewhere. A well-known example is the planting of trees to compensate for the greenhouse gas emissions from personal air travel. But does planting trees reduce global warming? Not in most places on the earth. The Carnegie Institution's ...

How we know we're not wrong about climate change A professor of History and Science Studies explains	Andrew Dessler	27 Jun 2007	Gristmill
For those interested in why the scientific community is so certain about climate change, take a look at this presentation and this book chapter, both by Naomi Oreskes. She does a great job explaining how science reaches conclusions, and why we can be pretty sure that humans are indeed warming the climate.

Science: Eh, who cares? Hansen says scientists need lovin', too	Kate Sheppard	26 Jun 2007	Gristmill
NASA climate scientist James Hansen has a new paper out, titled 'How Can We Avert Dangerous Climate Change,' which is actually a slightly-edited version of his testimony before Congress in April. The paper is available online here (PDF), and it's worth checking out, of course. But also interesting is the preamble Hansen included in his email announcing the new paper: President Eisenhower was arguably the last United States President to seek and value advice of scien ...

Scientific hubris? Climate change science questioned	Andrew Dessler	25 Jun 2007	Gristmill
In an op-ed in today's Washington Post, Emily Yoffe asks an interesting question: All this is not to say that it's not getting warmer and that curbing our profligate environmental ways is not a commendable and necessary goal. But perhaps this movement is sowing the seeds of its own destruction -- even as it believes the human species has sown its own. There must be a limit to how many calamitous films, books and television shows we, and our children, can absorb. ...

Hansen keeps sounding the alarm Is anyone listening?	David Roberts	19 Jun 2007	Gristmill
James Hansen has a new paper out, co-authored with six other scientists: "Climate Change and trace gases." It appears in the current issue of the Philosophical Transactions of the Royal Society, and Hansen says: "In my opinion, among our papers this one probably does the best job of making clear that the Earth is getting perilously close to climate changes that could run out of our control." Steve Connor has a writeup in The Independent. Sounds l ...

Should the IPCC be more extreme? Recent report published projecting values of sea-level rise	Andrew Dessler	08 Jun 2007	Gristmill
As anyone who reads my posts knows, I am a big fan of the IPCC reports. They are the best summary of what the scientific community knows about climate change and how confidently we know it. A recent article (subscription required, sorry) in Science suggests that some scientists view the IPCC as overly cautious: In the latest report, its fourth since 1990, the IPCC spoke for scientists in a calm, predictably conservative tone (Science, 9 February, p. 754). It is, ...
