Useless Energy
This is the important things that forgotten by all people in the earth. We always use energy too much for nothing. We always use all energy like electric energy, gas energy, etc. The energy that we used are so hard to get it again. If we use the energy too much, it need long time to reproduce it again, and it can make the nature circulation proccess disturbed. It also give an influence in making the global warming become worst. I think if we do this everytime, we just make the earth destroyed, because we lose all energy and the earth will received the sun ray more than before, then finally the little judgement day come.

Global Warming
Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-20th century and its projected continuation.
Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1][2] The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the temperature increase since the mid-twentieth century is “very likely” due to the increase in anthropogenic greenhouse gas concentrations.[3][2] Natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[4][5] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science,[6] including all of the national academies of science of the major industrialized countries.[7][8][9] While individual scientists have voiced disagreement with these findings,[10] the overwhelming majority of scientists working on climate change agree with the IPCC’s main conclusions.[11][12]
Climate model projections indicate that 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.[3] The uncertainty in this estimate comes about from differing estimates of future greenhouse gas emissions and from the use of models with differing climate sensitivity. Another uncertainty is how warming and related changes will vary from region to region around the globe. Although most studies focus on the period up to 2100, warming is expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. This results from the large heat capacity of the oceans.[3]
Increasing global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, likely including an expanse of the subtropical desert regions.[13] Other likely effects include increases in the intensity of extreme weather events, changes in agricultural yields, modifications of trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.
Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions. Political and public debate continues regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.
