Thursday April 05th 2012, 10:00 AMThe dramatic temperature increases that thawed the last ice age followed spikes in carbon dioxide levels in the air, a new study finds. Researchers say that further strengthens the scientific case explaining current man-made global warming. [News Source]
Ice age data bolsters greenhouse gas, warming link.
Climate and carbon: the link just got stronger.
Thursday April 05th 2012, 10:00 AMClimate scientists have long argued that ancient air trapped in Antarctic ice is the smoking gun that links carbon dioxide to global warming. [News Source]
Melting Arctic may redraw global geopolitical map.
Thursday April 05th 2012, 10:00 AMThis year's frenzy of oil and gas exploration in newly accessible Arctic waters could be the harbinger of even starker changes to come. If, as many scientists predict, currently inaccessible sea lanes across the top of the world become navigable in the coming decades, they could redraw global trading routes -- and perhaps geopolitics -- forever.

Titanic would encounter more icebergs today?
Thursday April 05th 2012, 10:00 AMA hundred years ago, on April 15, 1912, an iceberg brought down the supposedly unsinkable Titanic in the North Atlantic. If the legendary ship sailed today, it would likely encounter many more icebergs, possibly due to global warming, scientists say. [News Source]
Pollution playing a major role in sea temperatures.
Thursday April 05th 2012, 10:00 AMThe Atlantic Ocean is peculiar: Every few decades, the average temperature of surface water there changes dramatically. Scientists want to know why that is, especially because these temperature shifts affect the weather. New research suggests that human-created air pollution from aerosols is part of the cause.

Stopping climate change is cheaper than you think.
Thursday April 05th 2012, 10:00 AMYou've heard it before: politicians say they'd love to take action against climate change, but they're reeling from the sticker shock. Today, a new report from the UK's leading climate change watchdog refutes the oft-cited argument that climate action will herald economic Armageddon. [News Source]
The brighter side of air pollution.
Thursday April 05th 2012, 10:00 AMOne of the most persistent myths about human-caused global warming is that it should be driving temperatures steadily upward. [News Source]
Past global warming caused by thawing permafrost.
Thursday April 05th 2012, 10:00 AMA new study published in Nature not only finds that extreme rises in temperature are linked to an increase in greenhouse gases, but suggests for the first time that the carbon was released from thawing permafrost on land rather than the oceans. [News Source]
What the hail is going on?

Britain postpones June carbon permit auction.
Thursday April 05th 2012, 10:00 AMBritain postponed on Thursday a planned auction of 4 million European Union carbon permits to September from June due to uncertainty around the timing of the start of a single, EU-wide carbon registry. [News Source]
Tulane University geologists chronicle acceleration in sea-level rise.
Thursday April 05th 2012, 10:00 AMSea-level rise along the Gulf Coast, including Louisiana, occurred at a much faster rate in the past 100 years than in the 1,000 years prior to the nation’s industrialization, according to a new study by Tulane University geologists. [News Source]
