Global Warming

Global warming is a huge problem and it is going to take concerted and unified effort by governments, businesses and individuals to solve it. But nevertheless there are many little things we can do as humans to make a difference. With a little effort in changing some of our daily activities and routines, we can help reduce the amount of greenhouse gases that we put into the atmosphere. It's the only reasonable way to save our planet before it's too late.

Global warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. The Earth's climate is mostly influenced by the first six miles or so of the atmosphere which contains most of the matter making up the atmosphere. If you really think about it that is a very thin layer.

Continuing controversy over the extent of human influence on climate change suggests that a review of the latest findings on global warming written for a general audience will contribute to a wider understanding of his critical issue. Previous analyses of the global warming problem by the Marshall Institute have concentrated on the validity of climate models, the climate record as revealed in temperature observations, and the lack of a greenhouse signal in the temperature record to date.

The study begins with a review of evidence relating to claims that 1995 was the warmest year on record, and that anthropogenic global warming has caused and will cause a greater frequency of severe storms and extreme weather events, including blizzards and hurricanes. The remainder of the report concerns statements by the UN Intergovernmental Panel on Climate Change (IPCC) that for the first time it is now possible to discern in the temperature record a significant human influence on climate.

This most recent Marshall Institute review of scientific evidence on climate change confirms the earlier conclusion that predictions of an anthropogenic global warming have been greatly exaggerated, and that the human contribution to global warming over the course of the 21st century will be less than one degree Celsius and probably only a few tenths of a degree. Spread over a century, a temperature rise of this magnitude will be lost in the noise of natural climate fluctuations (Dr.S.Baliunas, (January 1995).

Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, which is an extremely significant increase, even on inter-glacial timescales. It is believed that human beings are responsible for this because the increase is almost perfectly correlated with increases in fossil fuel combustion, and also due other evidence, such as changes in the ratios of different carbon isotopes in atmospheric CO2 that are consistent with "anthropogenic" (human caused) emissions. The simple fact is that under "business as usual" conditions, we'll soon reach carbon dioxide concentrations that haven't been seen on Earth in the last 50 million years.
