Humans blamed for climate change

IPCC IVth Report Assessment: humans blamed for climate.

Even if the IVth report of the International Panel of Climate Change experts seems to be strong their is other scientist voices saying that the report seems below the thruth so a study published on the eve of the IPCC report suggested that the international body's previous reports may have actually been too conservative.

Writing in the journal Science, an international group of scientists concluded that temperatures and sea levels had been rising at or above the maximum rates proposed in the last report, which was published in 2001.

The paper compared the 2001 projections on temperature and sea level change report with what has actually happened.

The models had forecasted a temperature rise between about 0.15C-0.35C (0.27-0.63F) over this period. The actual rise of 0.33C (0.59F) was very close to the top of the IPCC's range.

A more dramatic picture emerged from the sea level comparison. The actual average level, measured by tide gauges and satellites, had risen faster than the intergovernmental panel of scientists predicted it would.

The IPCC's full climate science report will be released later in the year, as will other chapters looking at the probable impacts of climate change, options for adapting to those impacts, and possible routes to reducing emissions of greenhouse gases.
