Does Raise Always Mean One Step Forward?

The Earth that moves round the Sun, changing position once in several hours by replacing day by night and night by day, changes itself, too. And the disease of the Earth is called “Global Warming.” What are the changes the Earth underwent and what are the threats the inhabitants might face are analyzed in the data obtained by the World Meteorological Organization (WMO).

According to data the global mean surface temperature for 2007 is currently estimated at 0.41°C/0.74°F above the 1961-1990 annual average of 14.00°C/57.20°F.

Though the final data will be published in March 2008 It is available to make analysis on the basis of existing information. The temperature analysis made by WMO is based on two sources and these are: The combined dataset maintained by both the Hadley Center of the UK Metropolitan Office, and the Climatic Research Unit, University of East Anglia, UK. It is the source that ranked 2007 as the seventh warmest on record. But there are some other centers, too. The US Department of Commerce’s National Oceanic and Atmospheric Administration (NOAA), indicates that 2007 is likely to be the fifth warmest on record.

According to the World Meteorological Organization “2007 global temperatures have been averaged separately for both hemispheres. Surface temperatures for the northern hemisphere are likely to be the second warmest on record, at 0.63°C above the 30-year mean (1961-90) of 14.6°C/58.3°F. The southern hemisphere temperature is 0.20°C higher than the 30-year average of 13.4°C/56.1°F, making it the ninth warmest in the instrumental record since 1850. January 2007 was the warmest January in the global average temperature record at 12.7°C/54.9°F, compared to the 1961-1990 January long-term average of 12.1°C/53.8°F.”

Climate change is not the only obstacle the Earth faces but it also includes:

• Record-low Arctic sea ice extent, which led to first recorded opening of the Canadian Northwest Passage;
• The relatively small Antarctic Ozone Hole;
• Development of La Niña in the central and eastern Equatorial Pacific;
• Devastating floods, drought and storms in many places around the world.

Data shows that the winter and spring is ranked 4°C higher than the long-term monthly averages for January and April. In contrast to Bulgaria, the South of the United States, in August, where the highest temperature was fixed, Australia recorded its coldest ever June with the mean temperature dropping to 1.5°C below normal. South America experienced an unusually cold winter, bringing winds, blizzards and rare snowfall to various provinces with temperatures falling to -22°C/-7.6°F in Argentina and -18°C/-0.4°F in Chile in early July.

The joint press release also indicates the results and consequences about sea level. It continued to rise at rates substantially above the average for the 20th century of about 1.7 mm per year. global averaged sea level by 2007 is about 20 cm higher than the 1870 estimate. Modern satellite measurements show that since 1993 global averaged sea level has been rising at about 3 mm per year.

According to the Intergovernmental Panel on Climate Change’s 4th Assessment (Synthesis) Report, 2007, “warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.”

Two posts were already covered on global warming at Blogvasion:
Green Ethernet Technology To Solve Global Problems,
Global Warming Effects and Ways of Informing Society.

The last one got two comments, that show the importance and actuality of the issue on the global arena of problems. The representative of Right Democrat: A Mainstream Populist Voice indicated in the comment that “the best way to slow global warming would be to expand nuclear power,” and asked me to visit the following link http://www.youtube.com/watch?v=gsiE3Ldc8hM . I think that Video on You Tube “Dr. Patrick Moore on Nuclear Energy and Low CO2 Emissions” will be informative and productive for the Blogvasion readers, too.
