Global Warming (Finish)

Solar Variability is a natural cause it to change,Solar irradiance changes have been measured reliably by satellites for only 30 years. While a component of recent global warming may have been caused by the increased solar activity of the last solar cycle, that component was very small compared to the effects of additional greenhouse gases. But the Solar Variability change will not cause big change of the global temperature, and the sun have less bright it mean the minimum solar came,global warming jujst continue to occur.

Climate change is very likely having an impact now on our planet and its life, according to the latest installment of a report published by the IPCC. And the future problems caused by rising seas, growing deserts, and more frequent droughts all look set to affect the developing world more than rich countries, they add. The report is the second chapter of the IPCC's Fourth Assessment -- the most comprehensive summary yet of research into the causes and effects of climate change.
