Why the Global Warming Skeptics Are Wrong by William D. Nordhaus. The threat of climate change is an increasingly important environmental issue for the globe. Because the economic questions involved have received relatively little attention, I have been writing a nontechnical book for people who would like to see how market-based approaches could be used to formulate policy on climate change. When I showed an early draft to colleagues, their response was that I had left out the arguments of skeptics about climate change, and I accordingly addressed this at length. But one of the difficulties I found in examining the views of climate skeptics is that they are scattered widely in blogs, talks, and pamphlets. Then, I saw an opinion piece in The Wall Street Journal of January 27, 2012, by a group of sixteen scientists, entitled “No Need to Panic About Global Warming.”
Greenland Research Station Reveals Past and Future of Climate Change Impacts. Second in a three-part series.
SUMMIT STATION, Greenland -- At first glance, this research station on the highest point of Greenland's vast ice sheet doesn't look like much. A scattering of trailers perch on stilts high above the snow, with a neat grid of small yellow tents off to one side. Columbus Blamed For Little Ice Age. MINNEAPOLIS — By sailing to the New World, Christopher Columbus and other explorers who followed him may have set off a chain of events that cooled Europe’s climate.
The European conquest of the Americas decimated the people living there, leaving large areas of cleared land untended. Trees that filled in this territory pulled billions of tons of carbon dioxide from the atmosphere, Stanford University geochemist Richard Nevle reported October 11 at the Geological Society of America annual meeting. Such carbon dioxide removal could have diminished the heat-trapping capacity of the atmosphere and cooled the climate, Nevil and his colleagues have previously reported. Reign Check: Abundant Rainfall May Have Spurred Expansion of Genghis Khan's Empire.
The Mongol hordes led by Genghis Khan carved out the largest contiguous land empire history has ever witnessed, reaching at its apex from Asia's Pacific coast to eastern Europe and down into Persia and southeastern Asia.
Although conventional wisdom suggests drought may have pushed them across the steppe to conquer more bountiful lands, ancient, long-dead trees discovered in a forbidding lava field in Mongolia give evidence that unprecedented rains might actually have helped fuel their expansion. The Mongols took the Old World by storm in the 13th century. Their invasions and expansion are often attributed to the unstable climate they experienced on the steppes, "with them preying on others because they did not have a constant set of resources," says geographer Amy Hessl at West Virginia University.
"Now, we agree they experienced a variable climate. Farmers May Have Kicked Off Local Climate Change 3,500 Years Ago. Humans may have been causing climate change for much longer than we’ve been burning fossil fuels.
Iron-rich dust fuelled 4 million years of ice ages - environment - 03 August 2011. DUST is all that's needed to plunge the world into an ice age.
When blown into the sea, the iron it contains can fertilise plankton growth on a scale large enough to cause global temperatures to drop. Can Fracking and Carbon Sequestration Co-Exist? Natural gas production and carbon sequestration may be headed for an underground collision course.
That is the message from a new study finding that many of the same shale rock formations where companies want to extract gas also happen to sit above optimal sites envisioned for storing carbon dioxide underground that is captured from power plants and industrial facilities. The problem with this overlap, the researchers found, is that shale-gas extraction involves fracturing rock that could be needed as an impenetrable cover to hold CO2 underground permanently and prevent it from leaking back into the atmosphere. "Shale gas production through hydraulic fracturing can compromise future use of the shale as a caprock formation in a CO2 storage operation," said Michael Celia, a civil and environmental engineering professor at Princeton University and a co-author of the study.

For the benefit of anyone who has spent the past decade or so on a different planet, the most frequently asked questions about climate change on this one are as follows.
Is it getting warmer? Yes, surface temperatures have risen by 0.8°C from pre-industrial levels. Climate Skepticism Not Rooted In Science Illiteracy. People who strongly resist data indicating that human-induced climate change could spell catastrophe aren’t ignorant about science or numerical reasoning.
Quite the opposite, a new study finds: High science literacy actually boosts the likelihood that certain people will challenge what constitutes credible climate science. Who will be receptive to climate science, the study found, depends more on cultural factors such as attitudes toward commerce, government regulation and individualism than on scientific literacy. The Battle Over Climate Science. There's no police tape across Michael Mann's office doorway this morning.
Is Earth Nearing an Environmental "Tipping Point"? Human activities are pushing Earth toward a "tipping point" that could cause sudden, irreversible changes in relatively stable conditions that have allowed civilization to flourish, a new study warns.
There are signs that a toxic brew of climate change, habitat loss and population growth is dramatically reshaping life on Earth, an international team of researchers reported yesterday in the journal Nature. Those pressures are greater than the natural forces that caused the end of the last ice age roughly 11,700 years ago, a time when half the planet's large mammal species went extinct and humans migrated out of Africa.
"We are doing enough to cause one of these tipping points," said lead author Anthony Barnosky, a paleobiologist at the University of California, Berkeley. "The question now is, how close are we?

It's a great time to be depressed about the fate of the planet. The last United Nations confab on climate change, a November meeting in Durban, South Africa, suggested we're unlikely to see any new deal on greenhouse gasses having an impact before 2020. The Authoritarian Impulse and Climate Change « NoFrakkingConsensus. March 13, 2012 at 4:18 pm. NoFrakkingConsensus. When to Doubt a Scientific ‘Consensus’ A December 18 Washington Post poll, released on the final day of the ill-fated Copenhagen climate summit, reported “four in ten Americans now saying that they place little or no trust in what scientists have to say about the environment.” Nor is the poll an outlier. Several recent polls have found “climate change” skepticism rising faster than sea levels on Planet Algore (not to be confused with Planet Earth, where sea levels remain relatively stable).

India Balks at Greenhouse Gas Emission Cuts. India appears to be pressing the reset button on its international climate change commitments. In a submission to the U.N. Framework Convention on Climate Change last week, India declared it would not even consider scaling back more greenhouse gas emissions until after 2020 -- and then would do so only in exchange for Western dollars. It's an interpretation of the Durban Platform, reached after a hard-fought battle at the U.N. negotiations in Durban, South Africa, last year, that flies in the face of how the United States and Europe view the agreement.
The Climate Threat We Can Beat. For more than two decades, diplomats have struggled to slow global warming. They have negotiated two major treaties to achieve that goal, the 1992 UN Framework Convention on Climate Change and the 1997 Kyoto Protocol. And last year, at the UN Climate Change Conference in Durban, South Africa, they agreed to start talking about yet another treaty. A Tour of the New Geopolitics of Global Warming.
