Arguing from authority Articles about climate skeptics	Coby Beck	22 Jun 2007	Gristmill
Even while rejecting the authority of the most comprehensive and reviewed scientific document on any subject, namely the IPCC report, one of the most common climate delusionist tactics is the argument from authority. Whether it is Alexander Cockburn responding to George Monbiot or some anonymous person on some blog, everyone has some personal 'scientist' friend who assures them the rest of the world has gone mad. When an argument from authority is invoked it is perfect ...

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, ...

Scientists and alarmism The 'in it for the money' theory of climate science doesn't pan out	Andrew Dessler	29 May 2007	Gristmill
We have all heard the following argument: in order to get funding for research, the scientific community is forced to produce alarmist predictions of climate change. There's a lot wrong with this argument. But it recently occurred to me that it doesn't even make sense. In the latest IPCC reports, what the scientific community said is that our understanding of climate change is quite good (although not 'settled'). This does nothing to build up research funding. T ...

Biofuels and the poor The former: Not good for the latter	Maywa Montenegro	22 May 2007	Gristmill
How climate change will disproportionately affect the world's poor is a message making the rounds of late, after the publication of the second IPCC report earlier this year. How climate change policies, such as carbon taxes, will either help or hurt the poor is also a topic we've been discussing of late. Now researchers at the University of Minnesota have assessed the impact of an increased dependence on biofuels on the developing world ... and the outlook isn't ...

Clarion Caller An interview with renowned climate scientist James Hansen	Kate Sheppard	15 May 2007	Main Dish
James Hansen. Photo: nasa.gov James Hansen, NASA's top climate expert, believes scientists have an obligation to speak out when their findings have important implications for the public -- and he certainly put that belief into practice last year when he told The New York Times that the Bush administration was trying to muzzle his calls for reducing greenhouse-gas emissions. Hansen has been ...

Uh oh! Observed warming since 1990 is greater than the models predicted	Andrew Dessler	10 May 2007	Gristmill
An article in the May 4 issue of Science shows that observed warming in the 16 years since 1990 is greater than predicted by models. Perhaps models are underestimating future climate change. That would be bad news. 'Recent Climate Observations Compared to Projections' We present recent observed climate trends for carbon dioxide concentration, global mean air temperature, and global sea level, and we compare these trends to previous model projections as summa ...

Summary of the IPCC Summary for Policymakers, part II Summarizin' summaries, summarily	Joseph Romm	09 May 2007	Gristmill
Here is the second half of my summary of the IPCC summary (PDF): Energy Efficiency: It is often more cost-effective to invest in end-use energy efficiency improvement than in increasing energy supply to satisfy demand for energy services. Efficiency improvement has a positive effect on energy security, local and regional air pollution abatement, and employment. (In buildings): Energy efficiency options for new and existing buildings could considerably reduce ...

Summary of the IPCC Summary for Policymakers, Part I Summaries of a summary -- the new black?	Joseph Romm	07 May 2007	Gristmill
Finally, below is the first half of my summary of the IPCC summary (PDF): In 2030 macro-economic costs for multi-gas mitigation, consistent with emissions trajectories towards stabilization between 445 and 710 ppm CO2-eq, are estimated at between a 3% decrease of global GDP and a small increase, compared to the baseline. However, regional costs may differ significantly from global averages (high agreement, medium evidence). In 2050 global average macro-economic costs f ...

Highlights of the IPCC's mitigation report It ain't pretty	Joseph Romm	05 May 2007	Gristmill
I want to highlight a few points from the IPCC's Mitigation Report (PDF). First, even the most stringent global greenhouse gas targets can be met at a cost of a mere 0.1% of GDP per year! While the report is not explicit about when action should be taken, it does say that: In order to stabilize the concentration of GHGs in the atmosphere, emissions would need to peak and decline thereafter. The lower the stabilization level, the more quickly this peak and decline ...

Battle of the developed vs. the developing Climate change justice is contentious	Joseph Romm	04 May 2007	Gristmill
As this round of the IPCC unfolds, developing countries are scurrying to relieve themselves of any major responsibility for historic emissions and, consequently, aggressive mitigation policies. For example, China has requested inserting language that formally recognizes the percentage of emissions for which developed countries are responsible -- 95 percent from the pre-industrial era until 1950, and 77 percent from 1950 to the start of the millennium. China is als ...

Where There's a Way, There's a Will Third IPCC report says world can afford climate solutions		04 May 2007	Daily Grist
Where There's a Way, There's a Will Third IPCC report says world can afford climate solutions The third installment of the IPCC climate assessment is out, and the news is bad-good: it's going to take a lot of work to combat climate change, but it won't cost as much as many leaders have been claiming. The 120-nation Intergovernmental Panel on Climate Change says greenhouse gases, which have risen 70 percent s ...

IPCC out of date, again More current science paints an even grimmer picture	Joseph Romm	04 May 2007	Gristmill
Already, there are serious reservations about the final IPCC summary for policymakers, which was released today. The BBC leads the charge, noting that the economic models used to recommend mitigation policies aim to hold the atmospheric carbon dioxide concentration at 550 parts per million (ppm). However, more recent scientific evidence suggests, and I agree, that our policies need to keep concentrations much closer to 450 ppm. I certainly applaud the IPCC and ...

Another blow against denial New Monbiot piece	JMG	01 May 2007	Gristmill
From 'The Rich World's Policy on Greenhouse Gas Now Seems Clear: Millions Will Die,' by George Monbiot: Rich nations seeking to cut climate change have this in common: they lie. You won't find this statement in the draft of the new report by the Intergovernmental Panel on Climate Change, which was leaked to the Guardian last week. But as soon as you understand the numbers, the words form before your eyes. The governments making genuine efforts to tackle global warming are usi ...

One Fight In Bangkok Scientists, others gather in Thailand to finalize third IPCC report		30 Apr 2007	Daily Grist
One Fight In Bangkok Scientists, others gather in Thailand to finalize third IPCC report In its third report of the year, due out Friday, the Intergovernmental Panel on Climate Change will recommend climate solutions. (The first report confirmed the existence and science of our collective mess, and the second outlined its likely effects.) So what will save us? A draft released this weekend suggests nuclear p ...

Bush vs. Clinton on climate change Bush is working with a much stronger consensus	Andrew Dessler	19 Apr 2007	Gristmill
One argument in defense of George W. Bush's lack of action on climate change is some variation of this: 'Bill Clinton wasn't any better ... he never sent the Kyoto Protocol to the Senate.' This is true. But it also ignores one important fact. The science of climate change has improved dramatically since the mid-'90s. In its 1995 report, the Intergovernmental Panel on Climate Change (IPCC) summarized our knowledge about climate change by saying ... ... the balance o ...

Responsibility The view from Washington	Tom Athanasiou	18 Apr 2007	Gristmill
So here I am in Washington (the other one) in a homey B&B just eight blocks from the White House. I came here for a number of reasons, not the least of which is attending a conference called Climate Change and International Development (which was, by the way, recorded, and it is said that videos will be available here.) It was pretty good, and the less-public strategy meeting that followed it today (at the Friends of the Earth offices) was even better. Strategic ...

IPCC Working Group III goes after transportation pollution If you won't go after them, we will	Joseph Romm	17 Apr 2007	Gristmill
The IPCC reports are some of the most highly anticipated of 2007. An obvious sign? Within two weeks of one report's release, papers are already covering a leak from the next. IPCC Working Group III's focus is on mitigation, meaning a fair number of policy implications can be derived from its conclusions. So here's a hint for America's auto industry: the report calls for urgent action on road pollution. In the United States, there are 483 passenger cars per 1,00 ...

Summary of the IPCC Summary for Policymakers, part III This time, it's personal	Joseph Romm	11 Apr 2007	Gristmill
(Continued from parts I and II.) Last but not least (actually, what quite literally hits closest to home!): North America Moderate climate change in the early decades of the century is projected to increase aggregate yields of rain-fed agriculture by 5-20 percent, but with important variability among regions. Warming in Western mountains is projected to cause decreased snowpack, more winter flooding, and reduced summer flows, exacerbating competition for ove ...

A glimpse at IPCC WGIII Oh, the anticipation!	David Roberts	11 Apr 2007	Gristmill
The IPCC report I've most been looking forward to is from Working Group III, on mitigation. It looks like drafts of that report are already leaking -- Reuters has a (poorly written) rundown. From what I can tell through the muddy writing, the IPCC lays out a range of mitigation scenarios, which would run anywhere from 0.2 to 3.0 percent of global GDP: The IPCC scenario of a 0.2 percent loss in GDP in 2030 is based on stabilising greenhouse gases at 650 parts per mi ...

Political efforts to water down IPCC report A visual comparison	David Roberts	11 Apr 2007	Gristmill
When the IPCC WGII summary was released last week, there were media reports on last-minute clashes between scientists and political types -- the former pushing for the original strong language, the latter pushing to water it down. George Monbiot's column yesterday addressed the subject, in characteristically outraged tones. For those interested in the details, DeSmogBlog has compiled a comparison of a leaked version of the summary and the final summary released las ...

Summary of the IPCC Summary for Policymakers, part II Continued ...	Joseph Romm	11 Apr 2007	Gristmill
And now for the IPCC report's regional assessments, continued from yesterday:Africa By 2020, between 75 and 250 million people are projected to be exposed to an increase of water stress due to climate change. The area suitable for agriculture, the length of growing seasons, and yield potential, particularly along the margins of semi-arid and arid areas, are expected to decrease. This would further adversely affect food security and exacerbate malnutrition in the co ...

The IPCC, WGI's 4AR on the Scientific Basis of climate change. 29,000 observational data series crossed with expected changes to physical and biological systems based on those observations, with 89% consistency between the two.
