Speak softly and carry a big hockey stick Earth hotter now than in past 2,000 years	Joseph Romm	04 Sep 2008	Gristmill
The 'hockey stick' graph is a reconstruction of Northern Hemisphere temperatures over the past thousand years. It showed a sharp rise starting about a century ago. Global warming deniers and doubters have long attacked the graph asserting that we were as warm if not warmer hundreds of years ago. But a 2006 National Academy of Sciences report largely reaffirmed the analysis. A new peer-reviewed study by climatologists and earth scientists Michael Mann, Zhihua Zha ...

Breaking and Exiting Another large section of Canadian ice shelf breaks loose		04 Sep 2008	News
Posted at 6:21 AM on 04 Sep 2008 In a predictable yet mildly troubling reminder of the Arctic's continued ice melt, researchers say yet another massive ice chunk has broken off from an ice shelf in Canada. The Serson Ice Shelf just saw its mass more than halved when two large sections broke off recently, leaving it about 47 square miles smaller. For those of you keeping track at home, this summer has seen 19 square mi ...

I'll Huff and I'll Puff ... Warming seas make strong storms stronger, says new study		03 Sep 2008	News
Posted at 1:39 PM on 03 Sep 2008 As Gustav, Hanna, Ike, and Josephine become household names, more research has been added to the ongoing debate over the impact of climate change on hurricanes. A new study published in Nature indicates that warming seas have not increased the intensity of your everyday hurricane, but have made the mightiest storms even mightier. In essence, "if the seas continue to warm, w ...

Typhoon Marys and cyclone Janes Why future Katrinas and Gustavs will be much worse, part 2	Joseph Romm	03 Sep 2008	Gristmill
A lot of knee-jerk deniers (please don't write in -- I know that is redundant) misread 'part 1,' as I knew they would. I was not wading into the issue of whether global warming has already made intense tropical storms more common. That remains a great subject of debate, mostly because of the inadequacy of historical hurricane records, before the satellite era, and especially before WWII. That said, the North Atlantic seems special because much of the hurricane-formin ...

Stormy weather Should environmentalists jump on climate disasters?	Glenn Hurowitz	03 Sep 2008	Gristmill
There's a heated debate going on about whether environmentalists should jump on breaking climate disasters like Gustav and frame them in terms of global warming and other environmental issues. Open Left's Matt Stoller and Center for American Progress's Joseph Romm say yes, and 'anonymous environmental leader' says no (all are must-reads). In my recent book, Fear and Courage in the Democratic Party, I wrote about some research that might shed light on this question (th ...

Hurri-cane we stop these storms? Why global warming means killer storms worse than Katrina and Gustav, part 1	Joseph Romm	03 Sep 2008	Gristmill
Hurricanes can get much, much bigger and stronger than we have so far seen in the Atlantic. The most intense Pacific storm on record was Super Typhoon Tip in 1979, which reached maximum sustained winds of 190 mph near the center. On its wide rim, gale-force winds (39 mph) extended over a diameter of an astonishing 1,350 miles. It would have covered nearly half the continental United States. 'More than half the total hurricane damage in the U.S. (normalized for infla ...

Henry Hudson would be delighted North Pole an 'island' for first time in 125,000 years	Joseph Romm	03 Sep 2008	Gristmill
The fabled Northwest and Northeast passages are now open. That makes the North Pole an island for the first time in human history, most likely for the first time 'since the beginning of the last Ice Age 125,000 years ago.' In the last few days, however, Arctic ice melt has slowed, so we might not see a record this year, as the NSIDC daily graph makes clear: But whether a record is set this year has little bearing on the future of the Arctic. The National Snow ...

The storm of the century (so far) Will Gustav be the next Katrina?	Joseph Romm	29 Aug 2008	Gristmill
On August 23, 2005, a tropical depression formed 175 miles southeast of Nassau. By the next day, it had grown into tropical storm Katrina and was intensifying rapidly. Early in the evening on August 25, Hurricane Katrina made landfall near North Miami Beach. Even though it was only a Category 1 storm, with sustained wind speeds of about 80 miles-per-hour, it caused significant damage and flooding, and took 14 lives. The hurricane's quick nighttime trip across ...

Like Death, Warmed Over Arctic ice in a 'death spiral' as it hits second-lowest point ever		29 Aug 2008	News
Posted at 5:11 AM on 29 Aug 2008 Summer sea-ice melt in the Arctic is already the second-meltiest since satellite records began, and by the end of the melt season in mid-September, this year could surpass the all-time record low set last year, according to scientists at the National Snow and Ice Data Center. For the second time ever -- the first being last year -- the Northwest Passage shipping route is o ...

'Seven years to climate midnight' Brookings calls for action on climate change in WaPo op-ed	Joseph Romm	28 Aug 2008	Gristmill
The uber-centrist Brookings Institution joins the climate alarmist realist crowd. President Strobe Talbott and VP for foreign policy studies Carlos Pascual explain in a Washington Post op-ed: The world may have only seven years to start reducing the annual buildup in greenhouse gas emissions that otherwise threatens global catastrophe within several decades. The politics are a little bland for my taste, but that's to be expected from Brookings, which has moved cl ...

The great melting spot NSIDC: Arctic shortcuts open up; decline pace steady	Joseph Romm	26 Aug 2008	Gristmill
Fresh from its Olympic-record in denier debunking, the National Snow and Ice Data Center has released a new update: Sea ice extent is declining at a fairly brisk and steady pace. Surface melt has mostly ended, but the decline will continue for two to three more weeks because of melt from the bottom and sides of the ice. Amundsen's Northwest Passage is now navigable; the wider, deeper Northwest Passage through Parry Channel may also open in a matter of days. The North ...

The 100-meter retract A new Olympic record for retraction of a mistaken analysis of NSIDC data	Joseph Romm	26 Aug 2008	Gristmill
The gold medal goes to Steven Goddard of The Register. On Friday, Aug. 15, he published a scathing article, 'Arctic ice refuses to melt as ordered: There's something rotten north of Denmark' attacking the National Snow and Ice Data Center plot of Arctic Sea Ice Extent (below) that I and pretty much everyone else on the planet use. Based on some (mis)analysis too obscure for mortal men and women to follow, he concluded 'The problem is that this graph does not ap ...

In hot water Ocean temperture levels indicate planet has kept warming since 1998	Joseph Romm	21 Aug 2008	Gristmill
As part of their climate myth series, New Scientist cuts through the nonsense on what's happened globally in the last decade: In fact, the planet as a whole has warmed since 1998, even in the years when surface temperatures have fallen.According to the dataset of the UK Met Office Hadley Centre (see figure, right), 1998 was the warmest year by far since records began, but since 2003 there has been slight cooling.But according to the dataset of NASA's Goddard Inst ...

Climate whiplash	Andrew Dessler	18 Aug 2008	Gristmill
In a recent article in The New York Times, Andy Revkin talks about the whiplash effect: When science is testing new ideas, the result is often a two-papers-forward-one-paper-back intellectual tussle among competing research teams. When the work touches on issues that worry the public, affect the economy or polarize politics, the news media and advocates of all stripes dive in. Under nonstop scrutiny, conflicting findings can make news coverage veer from one extreme ...

Climate forecast: Hot and then even hotter NOAA says July 08 was fifth warmest on record	Joseph Romm	18 Aug 2008	Gristmill
I know we're supposed to be going into a period of cooling, at least according to people who don't believe in the scientific method. For those who do however, NOAA's National Climatic Data Center reports in its 'Climate of 2008 July in Historical Perspective': Based on preliminary data, the globally averaged combined land and sea surface temperature was the fifth warmest on record for July and the ninth warmest for the January-July year-to-date period. It is worth ...

Top of the food chain Global warming unleashes 'world's largest land predators' on humans	Joseph Romm	11 Aug 2008	Gristmill
It could be the premise of a new horror movie -- based on an all-too-true story. We have 'a new and unusual threat: a polar bear stuck on land due to climate change': Five scientists studying shorebirds in northern Alaska had to themselves take flight after a polar bear showed up at a time of year it should have been out on ice floes hunting seals.Polar bears would normally be out on sea ice in spring and summer, the group said in a statement, 'but with recent warm ...
