The developed countries are struggling to build national consensus for ambitious mitigation measures while the developing countries have gained the higher ground in the negotiations for the next climate deal by announcing voluntary sectoral emission reduction targets.
On the one hand, we will have more water around us with sea level rising. On the other hand, though, drought caused by climate change will leave possibly billions of people without clean water.
This will cause great health and global security issues. Most of these problems will be caused by water imbalances.
Even as the world prepares for the grand climate meet at Copenhagen this December, a large part of South India has gone under water. And while talks have already begun on coming up with an equitable deal and the very fear that there may be none, over 300 people have already lost their lives while millions are displaced and missing in this global warming related freak weather event, predicted well in advance by the IPCC in its Fourth Assessment Report in 2007.
Using Google Earth, you can look at climate effects under three different scenarios — 1) Confronting Climate Change — “with Al Gore”, 2) IPCC High Emissions Scenario, and 3) IPCC Low Emissions Scenario. Other new tools let you examine other aspects of climate change and how to adapt to climate change.
A new study by the World Wildlife Fund (WWF), released today, says that the effects of warming in the Arctic are “dire… far worse than previous projections.” Dr Martin Sommerkorn, senior climate change advisor for WWF’s Arctic program (who works on this stuff everyday) says: “What they found was a truly sobering picture.”
Scotland plans to reduce its carbon emissions by 42 percent by 2020 from 1990 levels, the most by any country.
As the earth warms, the melting of the earth’s two massive ice sheets—Antarctica and Greenland—could raise sea level enormously. If the Greenland ice sheet were to melt, it would raise sea level 7 meters (23 feet). Melting of the West Antarctic Ice Sheet would raise sea level 5 meters (16 feet). But even just partial melting of these ice sheets will have a dramatic effect on sea level rise.
By comparing observations spanning 43 years of population dynamics against models which project the declining levels of Antarctic sea ice, the study predicts that the giant penguins will be too slow to adapt to changes wrought by global warming.
The startling prediction is being called a conservative estimate by researchers, who claim that the data has as much as a four-in-five chance of being accurate. This number is particularly high because individual Emperor Penguins are long-lived and, as a result, biologically slow learners. Thus, they are unlikely to shift their breeding patterns fast enough to match the rapidly changing climate.
“Taken together, the ice sheets in Greenland and
Antarctica have very likely been contributing to sea
level rise over 1993 to 2003.” IPCC 4th Assessment Report
Clean coal has been getting a lot of attention lately. Both Mr. McCain and Mr. Obama consider it to be an important piece in their energy plans. Even the recent $900 billion bailout package included $1.5 billion for clean coal. Because coal is so plentiful and relatively cheap in the US, the notion of clean coal is particularly appealing. Unfortunately, clean coal is a myth.
Here’s why clean coal is so dirty:
30% more energy is required to pump carbon underground for carbon capture and sequestration (CCS). The captured carbon dioxide has to be compressed to 100 times the atmospheric pressure, transferred to an underground storage reservoir and then pumped in the ground. All of this requires large amounts of energy, thus the coal plant must burn an additional 30% more coal to generate the same amount of usable electricity.
