The Global Warming Statistics

Do we all know that , the Global surface temperature increased by 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005. Most conspicuously, according to the latest IPCC report the global surface temperature will likely to rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century.

These basic global warming statistics have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries like “Australian Academy of Sciences, Royal Flemish Academy of Belgium for Sciences and the Arts, Brazilian Academy of Sciences, Royal Society of Canada, Caribbean Academy of Sciences, Chinese Academy of Sciences, French Academy of Sciences, German Academy of Natural Scientists Leopoldina, Indian National Science Academy, Indonesian Academy of Sciences, Royal Irish Academy, Accademia Nazionale dei Lincei (Italy), Academy of Sciences Malaysia, Academy Council of the Royal Society of New Zealand, Royal Swedish Academy of Sciences, and Royal Society (UK),etc ”.

The Intergovernmental Panel on Climate Change (IPCC) also concludes that anthropogenic (human made) greenhouse gases, such as CO and CO2 ,are responsible for most of the observed temperature increase since the middle of the twentieth century, and that natural phenomena such as solar variation and volcanoes had a small warming effect from Pre-industrial times to 1950 and a small cooling effect afterward.

Most of the global warming statistics are focused on the period up to year 2100. However, global warming is expected to continue beyond year 2100, even if the emissions stop, the global warming will continue to increase because of the large heat capacity of the oceans and the long lifetime of carbon dioxide (co2) in the atmosphere.

Now, based on the above global warming statistics, the very first question arises “What would be the effects of global warming?”

The answer is more aroused and nonjudgmental, the full increase in alarming global warming statistics would cause sea levels to rise and also change in the amount and pattern of precipitation, likely including expansion of subtropical deserts. The continuing retreat of glaciers, permafrost and sea ice is expected, with the Arctic region being particularly affected. The other regions also likely to be effected by shrinkage of the Amazon rain forest and Boreal forests, increases in the intensity of extreme weather events like Tsunami and Hurricanes, species extinctions and changes in agricultural yields.

The available Global warming prevention options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, Geo engineering to reverse global warming.

As political and public debate continues regarding the appropriate response to global warming. Most of the national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions. A successor to the first commitment period of the Kyoto protocol is expected to be agreed at the “COP15–United Nations Climate Change Conference” talks in December 2009.
