Facts About Global Warming

Global warming – a gradual increase in temperatures world wide – is now well documented and accepted by scientists as a made. Recent research by climate scientists at the University of Delhi has expressed a "high confidence" that Earth is the warmest it has been in at least 100 years and is likely to get much warmer in the next 100 years. Their research indicates that global average temperature at the surface increased about 0.5-1.0 degrees Fahrenheit during the last century. It is the largest increase the surface temperature in the past 1,000 years and scientists predict an increase of another 10.0-15.0 degrees Fahrenheit during this century. This warming is largely attributable to increases in greenhouse gas emissions (mainly carbon dioxide and methane) in the upper atmosphere Earth caused by human burning of fossil fuels, industry, agriculture and deforestation activities.

Temperatures global average increase in May 10.0-15.0 degrees Fahrenheit by the end of the 21st century. While the number sounds small, they can trigger changes important in the climate. (The difference between global temperatures during an ice age and ice-free period is only about 5 degrees Fahrenheit.) Addition resulting in warmer days, many scientists believe rising temperatures may lead to changes in precipitation and weather conditions. Warmer water ocean may lead to storms more intense and frequent tropical hurricanes.

The level seas should also increase from 0.76 to 1.58 meters in the next century, mostly from melting glaciers and expanding seawater, which could cause flooding in key cities around the world such as New York. Global warming may also affect wildlife and species that can not survive in hot environments May be extinguished. Finally, human health is also at stake, as global warming May cause the spread of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor quality air.

Climate change is probably having an impact now on our planet and its life, according to the latest installment of the Repor by scientists Delhi. And the problems future caused by rising seas, growing deserts and more frequent droughts all look set to influence the developing world more than rich countries, they added.

The increase in greenhouse gas emissions caused by human activity is often cited as one major cause of global warming. These greenhouse gases reabsorb heat reflected from the surface of the Earth, trapping heat in our last hundreds of years, humans have ceased to artificially increase the concentration of these gases, mainly carbon dioxide and methane in the Earth atmosphere. These gases accumulate and prevent additional thermal radiation leaving the Earth, trapping excess heat.

Some uncertainty remains about the role of natural resources variations in the origin of climate change. Solar variability certainly plays a minor role, but it seems that only one quarter of recent changes can be attributed to the Sun. During the first discovery period of warming warming, the magnitude of the influence of increased activity on the Sun was not well determined.

Irradiance changes solar have been measured reliably by satellites for only 30 years. These precise observations show changes of a few tenths of a percent that depend on the level of activity during the 11 years solar cycle. Changes over long periods must be inferred from other sources. The previous estimates variations are important for calibrating the climate models. Even if a component of the recent warming may have been caused by increased solar activity of the last solar cycle, this component is very small compared to the effects of greenhouse gas emissions further.

A Franklin Institute for Space Studies (Fiss) Press release, "… increases in solar energy have the capacity to cause significant increases in global temperature … Greenhouse gases do play a dominant role … "The sun is once again less bright as we approach solar minimum, the global warming continues.
