Climate Change

The U.N. Intergovernmental Panel on Climate Change (IPCC) has issued its second of four planned reports examining the state of climate science. This one summarizes what the scientific literature says about “Impacts, Adaptation, and Vulnerability” (big PDF here). As with every recent IPCC report, it is super-cautious to a fault and yet still incredibly alarming.

Two days after a U.N. report warned of increased famine, war, and poverty from unmitigated carbon emissions, the Republican-led House of Representatives on Tuesday passed a bill that would require the National Oceanic and Atmospheric Administration (NOAA) to focus less on studying climate change, and more on predicting storms. The bill, introduced last June by Rep.

Violent conflicts and threats to the territorial integrity of some of the world’s most vulnerable countries are among the more ominous risks posed by an ever-warming planet, according to the UN organization given the task of assessing the impacts of climate change.

There is much to be desired in the mainstream media's coverage of energy politics and climate change, but perhaps the single most important fact that gets consistently overlooked -- that is scarcely apprehended by the general public and yet comes to mind for me every time a new pipeline or oil field gets approved -- is that greenhouse-driven warming operates on an extremely delayed timescale.

Air pollution kills about 7 million people a year and is linked to 1 in 8 deaths worldwide, according to a report released Tuesday by the World Health Organization. The finding more than doubles previous estimates “and confirms that air pollution is now the world’s largest single environmental health risk,” the agency said.

Exxon Mobil Corp. is leading a parade of energy companies that will confront the issue of the so-called “carbon bubble” – the idea that fossil-fuel assets such as Canada’s oil sands are overvalued and risky for investors in a world that must reduce its greenhouse gas emissions. In an agreement with institutional shareholders, Exxon has agreed to disclosure by the end of March of how climate change regulations could affect the value of its worldwide assets, including its major holdings in Alberta’s oil sands.

When faced with intractable problems, we often make up stories to console ourselves. The boat’s not really sinking, we say: We’re just going through a rough patch. We’re not headed for disaster; we’ve just been blown off course. Better to keep a bright outlook on things, we presume, than to acknowledge our desperate situation.

The American Association for the Advancement of Science came as close as such a respectable institution can to screaming an alarm last week. "As scientists, it is not our role to tell people what they should do," it said as it began one of those sentences that you know will build to a "but".

Last year BP projected global climate pollution would "most likely" surge 26% by 2030. As I reported at the time, this would crank up the Earth's thermostat a disastrous +4C according to the International Energy Agency (IEA). That is twice the +2C threshold for "dangerous climate change" that all major nations have promised to stay below.

Air pollution over Asia, most of which is coming from China, is affecting the world’s weather.
