Arctic sea ice appears likely to reach a record minimum extent this year; as Greg Laden says, “It is almost like the Earth is warming up or something.” The lowest extent of Arctic sea ice on record (since observations began in 1979) occurred in 2012, the second-lowest in 2007, and the third-lowest in 2015. On…

Fracked Over for Natural Gas

Research makes it increasingly clear that along with drilling for oil and mining coal, extracting natural gas from deep underground causes serious damage to the environment and to public health. On The Pump Handle, Kim Krisberg examines the contamination that may result from dumping fracking wastewater into disposal wells, writing “about 1,000 different chemicals are…

Well-Manicured Wastelands

On Pharyngula, PZ Myers doesn’t just want cut your grass—he wants to tear it out by the roots and leave it to rot in the sun. He quotes J. Crumpler on The Roaming Ecologist, who calls lawns “sterile, chemically-filled, artificial environments […] that provide no benefits over the long term; no food, no clean water,…

Et tu, Exxon?

New reporting by Inside Climate News shows that petroleum giant Exxon knew, more than thirty years ago, that burning too much fossil fuel would cause catastrophic climate change. Comparing Exxon’s subsequent emphasis on profits over planetary health to the efforts of Big Tobacco hiding the dangers of cigarettes, PZ Myers writes “the future is going…

No Rest for the Warming

Climate change denialists are apt to grasp at straws, which may explain their heralding of a global warming “hiatus” or “pause” that since 1998 has supposedly invalidated scientific consensus and its models of climate change. Clearer and more clever heads have renamed the hiatus a “faux pause,” playing off the French faux pas which means…

Denialists are Doomed

It’s been a frigid winter in much of the United States, but Greg Laden notes that the country covers only 1.5% of the Earth’s surface, and overall the planet just experienced the fourth-warmest January on record.  Meanwhile global warming denialists are resorting to every rhetorical trick in the book, such as comparing their increasingly outnumbered…

Solar cells made with bismuth vanadate achieve a surface area of 32 square meters per gram.  This compound can be paired with cheap oxides to split water molecules (and make hydrogen) with record efficiency. Short-term geoengineering could postpone global warming, only to have it happen more quickly in the future. Carotenoids tinge blackbird bills a deep orange,…

Hot Winter Days

The anti-scientific M.O. of some political conservatives was in full swing during the ‘polar vortex,’ as frigid weather brought south from the Arctic led many commentators to scoff, “look how cold it is, can you believe anyone thinks the Earth is getting warmer?” Coby Beck adds some perspective from climate historian Christopher C. Burt on…

Confidence on Warming from IPCC

The fifth assessment report of the Intergovernmental Panel on Climate Change was released last week, saying that global warming is occurring without a doubt, and human activity is extremely likely to be the cause.  Greg Laden shares a number of graphics from the report, summarizing “It is getting hotter. It is getting wetter, or dryer,…

Life has been growing on Earth for about 4 billion years, and during that time there have been a handful of mass extinctions that have wiped out a large percentage of complex lifeforms.  Asteroid impact, volcanic eruption, climate change, anoxia, and poison have dispatched untold numbers of once-successful species to total oblivion or a few…
