Gulf oil spill: Two years later, safety lessons ignored

In its rush to pump more oil, America is ignoring the key lesson of the Gulf oil spill two years ago. Complex drilling, wherever it occurs, comes with unknowable risks.
President Algae? Obama not green enough, say environmentalists

President Obama has blocked the Keystone pipeline, backed biofuels, and prioritizes the earth over people, say GOP presidential candidates. Environmentalists say Obama is a big disappointment. Who's right?
Greenland's ice sheet: Climate change outlook gets a little more dire

If temperatures reach 1.6 degrees C above preindustrial levels, the iconic ice sheet will probably tip toward irreversible loss. With climate change, temperatures have already risen 0.8 degrees C.
Ice, ice baby: Old arctic ice disappearing faster than younger thin ice

Typically the thicker, older ice survives through the summer melt season (hence, it's called multi-year ice), while the younger ice that forms over the winter melts as quickly as it formed.
Earth's next supercontinent dubbed Amasia, when to expect it

Supercontinents are giant landmasses made up of more than one continental core. The best-known supercontinent, Pangaea, was once the world's only continent — it was on it that the dinosaurs arose — and was the progenitor of today's continents.
Volcanic eruptions emerge as lead cause for Little Ice Age

The Little Ice Age began in the late 13th century, scientists now posit, and lasted about 400 years. Some regions cooled significantly. A series of volcanic eruptions has become a leading culprit.
Global warming: winners and losers in the Arctic's 'new normal'

The Arctic Report Card study suggests that changes at the top of the world have led to unusual weather patterns, a greener Greenland, and lots of plankton. At least the whales are pleased.
Global warming a threat to polar bears? Judge orders review of US rule.

A judge rules that the US has met its obligations for protecting polar bears, but ordered a review of a special rule that excludes greenhouse gases from the list of threats to the bears.
Extent of Arctic summer sea ice at record low level

New data indicates the continuation of a long-term decline in summer ice underway since at least 1979. Researchers say roughly half the decline can be attributed to global warming.
Drilling for oil in Arctic Ocean is fraught with danger

This month the US approved four wells for drilling by Shell Oil in the Arctic Ocean off Alaska, an energy frontier. But Shell's plan to recover after an oil spill is completely inadequate, given the region's remoteness and weather.
Russia's Arctic 'sea grab'

Russia is expected within months to claim to the United Nations its right to annex about 380,000 square miles of the Arctic.
Woolly mammoth may have interbred with elephants

Woolly mammoth roamed the planet for more than a million years, ranging from Europe to Asia to North America. Nearly all of these giants vanished from Siberia by about 10,000 years ago.
Winter's freezing, so what's with Arctic sea ice?

An unusually warm January has limited the return of Arctic sea ice, whose extent set a record low for the month. The ice's ability to reflect sunlight back into space has a significant influence on climate worldwide.
Global warming: Impact of receding snow and ice surprises scientists

The seasonal cooling effect of light-reflecting snow and ice in the Northern Hemisphere may be weakening at twice the rate predicted by climate models, a new study shows, accelerating the impact of global warming.
Where polar bears might go if climate change doesn't slow

If climate change leads to ice collecting in one general area in the Arctic Ocean, it might be enough to provide a last 'refuge' for many Arctic inhabitants, including polar bears.
Melting Arctic ice heralds new polar hybrids: Pizzlies and more

A pizzlie is a cross between a polar bear and a grizzly bear, and this new hybrid animal may foreshadow as many as 34 hybrids to come as Arctic ice melts, say scientists.

The peculiar dinosaurs of Laramidia: weird horns and more

The discovery of two new dinosaur species in the American West – which, 76 million years ago, was part of a continent called Laramidia – has scientists thinking about odd horns and why certain species didn't appear to spread out across all Laramidia.

Ice island that fell off Greenland glacier could pose threat to oil, shipping

Ice island: Potentially in the path of this unstoppable giant from Greenland are oil platforms and shipping lanes — and any collision could do untold damage.
Temperatures hit record highs globally. El Nino or global warming?

The first half of 2010 was the hottest six-month period recorded globally with temperatures around the globe 2 to 3 degrees Fahrenheit above averages.
NASA plans to boldly go to the Arctic

The mission will seek to unlock clues about the changing Arctic climate and the shifting ice conditions that affect ocean ecosystems.
Arctic sea ice at lowest point in thousands of years

Warming at the North Pole caused by the buildup of atmospheric greenhouse gases has reduced the ice that normally covers the Arctic Ocean at its lowest point in a few thousand years, a new study suggests.
BP oil spill: an accounting of its impacts after 39 days

Corporate behavior, drilling methods, regulators’ roles, and the search for oil alternatives all are reexamined in the wake of the BP oil spill in the Gulf of Mexico.
