Global warming: Sea level may rise 7-82 cm by century-end

Image
New predictions indicate that the amount of sea level rise by the end of this century will be between 7- 82 cm – depending on the amount of warming that occurs. Placing limits on the amount of sea level rise over the next century is one of the most pressing challenges for climate scientists. Dr Mark Siddall from the University of Bristol, together with colleagues from Switzerland and the US, used fossil coral data and temperature records derived from ice-core measurements to reconstruct sea level fluctuations in response to changing climate for the past 22,000 years, a period that covers the transition from glacial maximum to the warm Holocene interglacial period. By considering how sea level has responded to temperature since the end of the last glacial period, Siddall and colleagues predict that the amount of sea level rise by the end of this century will be similar to that projected by the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). According to...

What kind of "issue" is global warming?

I feel like a doomsayer at times. You see, I work as a door-to-door campaigner for a local environmental organization, and sometimes I feel like the watchman who comes a-knocking, warning the village of raiders from the far east. "So I'm sure you've heard of the problems global warming has caused," I say to a poor, unsuspecting homeowner, as part of my usual rap. "The last week it's been rather cold, actually. I don't think global warming is happening," he responds. I smile, nod, then bid him goodbye. The environment is a slow, sleepy giant. It takes a lot to wake him up, but when he does wake up, he is awakened (just catch the previews for the "2012" movie). At the moment, he is just barely stirring, tossing around in his sleep. We haven't seen all he can do yet. We can draw the charts, cite the figures - the giant will do so and so when he awakes - but until people feel his breath down their necks, the giant of climate change is just ...

India to fight warming, but won't accept emission caps

NEW DELHI : Prime Minister Manmohan Singh on Wednesday admitted that India had for the first time agreed to join the effort to cap the rise in global temperatures to 2 degrees from the pre-industrial level. But he strongly denied that it was a climbdown from its position not to accept binding emission cut targets. In a debate that for the first time saw climate change politics echo so deep in Parliament, Singh said the controversial Major Economic Forum declaration adopted at L’Aquila in Italy was “not a declaration of climate change policy by India”. Singh was speaking against the backdrop of suspicion in certain quarters that India’s agreeing to be part of the endeavour to adhere to the 2 degree threshold would lead to its acquiescence to pressure from the US-led developed bloc to take binding emission cut targets. He described such an interpretation as “misleading” and “one-sided.” The MEF is a US-backed initiative with 16 countries, including the G8 and emerging economies, to buil...

Heat-tolerant Coral Reefs Discovered: May Survive Global Warming

Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change। But now Stanford University scientists have found evidence that some coral reefs are adapting and may actually survive global वार्मिन। A toppled but surviving table-top coral at Ofu Island, American Samoa.

Palumbi and his Stanford colleagues began studying the resiliency of coral reefs in the Pacific Ocean in 2006 with the support of a Woods Institute Environmental Venture Project grant. The project has expanded and is now being funded by Co...
