The Reality Of Global Warming

The Reality Of Global Warming by Arthor Pens

Global warming is happening because of Carbon dioxide being released into our atmosphere. This is like the city smogs that we used to see in the 1900's, retaining or trapping the infrared heat from the sun in the atmosphere. Global mean temperature rises can be directly correlated to the mean increase in Carbon Dioxide in our atmosphere

There is significant evidence that our planet's weather and climate patterns are changing rapidly as a direct result of Global Warming. Droughts, receding glaciers and ice caps, extreme storms, rises in ocean temperatures and sea levels, shifts in distribution of organisms and diseases. Many think human activities are a significant contributing cause. As of this year, compelling scientific evidence has come to light to quantify this issue (Oct 2007). The rate at which Carbon Dioxide is being absorbed by the world's oceans has now depreciated significantly. This is because oceans are now overloaded with Carbon Dioxide. From this point forward, more and more of our CO2 output will go straight into the atmosphere, adding to global warming

A warming atmosphere and seas make for loads of extra energy available for the creation of abnormal weather patterns. Around the world, recent data shows an increase in severity of storms, droughts, rainfall, and floods. The disastrous hurricane season of 2005 was just one indication of how synergistic weather is with sea level rise, resulting in loss of wetlands, social issues, and the ability of governments to respond. Three storms strengthened to category 5 in the Atlantic Basin for the first time in a single season (Katrina, Rita, and Wilma). An unprecedented 27 named tropical storms formed, according to NOAA, and more than half of them became hurricanes

"The Arctic is receding very quickly (as a direct result of Global Warming) according to reports from scientists and arctic natives. The Arctic Climate Impact Assessment was released in late 2004, and shows changes from the ice at the North Pole to animals and human settlements. More recent reports from Greenland reveal glaciers moving meters per hour and rapidly thinning. The Arctic ice cap is shrinking in summer to the smallest it has ever been in modern measurements, and even winter cold has not been refreezing it as much as before. Basically, there's a rise in overall sea level going on, coupled with an increase in violent weather, so coastal areas will get hit very hard from now on.

In effect, we can now expect all previous climate change models to be obsolete. Rather like a movie straight out of Hollywood, you can imagine a scientist trying to explain to the president how a slowing in the rate of CO2 absorption by the world's oceans translates directly into increased CO2 in the atmosphere and that "we are now expecting a 2 degree rise in global temperatures in the next 10 years rather than the 50 years previously estimated Mr President." Or for you gas guzzling Americans: Forget any major coastal cities Mr President. I would also suggest that New Orleans will not need re-development or more capital expense. I foresee that a further category 4 or above hurricane will destroy any Levy's around the coastal areas. Substantial sea rises will prevent any attempts to protect these areas.
