No ice loss seen in major Himalayan glaciers

One of the world’s biggest glacier regions has so far resisted global warming that has ravaged mountain ice elsewhere, scientists reported on Sunday. For years, experts have debated the state of glaciers that smother nearly 20,000 square kilometres (7,700 sq. miles) of theKarakoram range in the western Himalayas. Straddling parts of China, Pakistan and India, the…

Global warming scientists foresee Sun-reflecting cities

PARIS — Scientists sketched a vision on Friday of converting the world’s cities into giant sunlight reflectors to help fight global warming but met with scepticism from fellow academics. Gradually replacing traditional urban roofs and roads with white or lighter-coloured materials would yield a cooling benefit that, over 50 years,…

New research proves rising carbon dioxide levels led to climate change before

A scientific conundrum that has puzzled climate experts for years may have been solved with the publication of research showing how an increase in carbon dioxide levels in the atmosphere contributed to rising temperatures millions of years ago. The paper, published on Wednesday in the journal Nature, has wide-ranging implications…

Science is political. Get over it.

I may get tired of using Pete Campbell pulling faces to illustrate my posts, but not yet. Not yet. I remember how, just a couple of years ago, there was a lot of hand-wringing in skeptic circles over whether or not to apply rationalist thinking to religious claims, mainly because…

Worldwide water crisis looms without action on waste: UN

Water problems in many parts of the world are chronic and without a crackdown on waste will worsen as demand for food rises and climate change intensifies, the UN warned on Sunday. Issued on the eve of a six-day gathering on world water issues, the United Nations, in a massive…

Even mild global warming could completely melt Greenland’s ice cap

The Greenland icesheet is more sensitive to global warming than thought, for just a relatively small — but very long term — temperature rise would melt it completely, according to a study published on Sunday. Previous research has suggested it would need warming of at least 3.1 degrees Celsius (5.6…

Santorum: Global warming is ‘political science’

Republican presidential candidate Rick Santorum on Friday blasted rivals former Massachusetts Gov. Mitt Romney and former House Speaker Newt Gingrich for their past support of legislation to combat global warming, saying that politicians shouldn’t change “when the climate changes.” “When the climate changed about man-made global warming in this country…

Astrophysicist deGrasse Tyson schools former GM exec Lutz on climate change

Popular astrophysicist and director of the Hayden Planetarium at the American Museum of Natural History Neil deGrasse Tyson schooled former vice-chairman of General Motors Bob Lutz on the reality of climate change during Friday night's edition of Real Time with Bill Maher. …

More Americans believe in climate change: poll

WASHINGTON — Nearly two-thirds of Americans believe that climate change is real — the highest level in two years — as the public trusted its own observations of rising temperatures, a poll said Tuesday. The growing acceptance of global warming comes despite fierce political division over the issue in the…

Stark warning emerges from summit: science is ‘under siege’

A stark theme emerged from an annual scientific get-together in Vancouver: the world must be helped to believe in science again or it could be too late to save our planet. Science is “under siege,” top academics and educators were warned repeatedly at the American Association for the Advancement of…
