Oxfam Australia says that climate change could leave up to 75 million people in the Asia-Pacific region homeless by 2050. The Future is Here: Climate Change says that these island nations are already suffering from drought, food shortages and rising water levels.
A majority of Americans continue believe that climate change is correctly portrayed or even underestimated in the news media, but a record high 41 percent believe risks are exaggerated.
It's a vocal 41 percent, and they draw on a stock set of arguments to attack the credibility of scientists, politicians and environmentalists who claim that humans are spurring dangerous climate change. Like me, you may wonder where these arguments come from and whether they have any validity.
The most common argument, and the one I will focus on in this first of several installments, is that many credible scientists dispute the theory of anthropogenic (or human-caused) climate change asserted by U.N. scientists in the 2007 IPCC report that found that humans were almost certainly causing the climate to change.

Though simultaneously praising the 2-degree commitment as "clearly a big step forward" in international talks, IPCC Chairman Rajendra Pachauri told reporters here yesterday that G-8 leaders failed to heed warnings that global greenhouse gas emissions levels must peak by 2015. Nations must also start to come up with concrete plans for rapidly slashing emissions afterward, Pachauri said.
"Climate change is the greatest challenge facing this and future generations," he said at a press conference in New York. "Emissions are rising and the clock is ticking."
The new projections, published this month in the American Meteorological Society's Journal of Climate, indicate a median probability of surface warming of 5.2 degrees Celsius by 2100, with a 90% probability range of 3.5 to 7.4 degrees. This can be compared to a median projected increase in the 2003 study of just 2.4 degrees.
