Global Warming

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation.

The average global air temperature near the Earth's surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations" via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.

These basic conclusions have been endorsed by at least thirty scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some findings of the IPCC, the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.

Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.

An Inconvenient Truth

You’ve seen An Inconvenient Truth. You’ve made changes in your life to reduce your carbon footprint. Looking for something else to do to help solve the climate crisis? How about learning how to give the presentation that is at the
heart of An Inconvenient Truth?

Starting this Fall, Al Gore and a team of renowned climate change scientists and educators will train more than 1,000 individuals to give a version of his presentation on the effects of - and solutions for - global warming, to community groups throughout the U.S.

Seven training sessions will be held in Nashville Tennessee from late September 2006 to January 2007. Each training session will be 2 days long, is free of charge (trainees are responsible for their transportation, accommodation and meals), and open to individuals of all ages, educational and technical backgrounds.

The two-day program is designed to familiarize trainees with the climate change science, equip them with new presentation skills, and develop a new dynamic online learning community for ongoing activities.

The Fact and the Act

Start from now on, we are need and must apply "Green Technology", Our Blue planet (Earth) already in crisis and need help. Many anomalies happen such as the Rise of air Temperature, Flood, Dry season, etc. This is what we call as the Effect of "Global Warming".

Have you seen the Movie "An Inconvenient Truth”, which showing to us the fact that already happens in our daily life, Global Warming caused by Human contribution of CO2 gas. Our Earth is crying.

Research and Development about Green Technology are in progress. In Newspaper, Television, and Internet, we can start hear many new innovation of green tech product, such as Green Fuel, auto pot, environmentally battery, Recycling trash, etc. These were good news for us and for our Earth.

Let's open our mind and start supporting, by starting with our self, our home, our office, our city, our country, and our planet. Let’s get greener.
