FACTBOX-Reports by the U.N. climate panel

(Reuters) - Scientists who advise the United Nations about climate change will issue a report in Brussels on Friday, the second of four this year outlining increasing risks from global warming.

CALENDAR

PARIS, Feb 2 - The first IPCC report, an overview of the science of global warming, said that it was "very likely" or at least 90 percent certain that mankind was to blame for most of the warming in the last half century.

The previous report in 2001 had put the probability at "likely", or at least 66 percent. The new report projected a "best estimate" that temperatures would rise by 1.8 to 4.0 degrees Celsius (3.2-7.2 Fahrenheit) this century.

BRUSSELS, April 6 - The second report will detail the likely impacts of climate change around the globe, such as on health, farming and water availability.

BANGKOK, May 4 - The third report, "Mitigation of Climate Change", will analyse ways to fight global warming, including options and costs for reining in emissions of greenhouse gases.

VALENCIA, Spain, Nov 16 - A fourth "Synthesis Report" will sum up all the findings.
