This paper highlights some important issues contained in the draft report from the Intergovernmental Panel on Climate Change (IPCC). The first issue focuses on the global warming estimate of IPCC indicating an increase in the global temperature. In 1995 IPCC estimates put the average global temperature increase by the end of this century at 1.5-4.0 degrees Celsius while in this report the newest estimate is 1.5-6.0 degrees Celsius. The second issue states that a firmer association between human activities and climate has emerged. Even the most skeptical climatologist in the IPCC group has conceded that warming bears an anthropogenic handprint. Another important issue is the rising evidence suggesting that past global temperature shifts in climate may have been triggered by major shifts in patterns of ocean circulation: the major conveyor of heat from low to high altitudes. Overall it is noted that the 2000 IPCC report raises the prospect of serious risk to a higher level and although there seems to be progress from the initiatives of the private sector governments ought to be paying more attention and address the issue immediately.
