Global warming is the increase in the average temperature of 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 between the start and the end of the 20th century The Intergovernmental Panel on Climate Change concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanism produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.
Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C during the 21st century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Most studies focus on the period up to the year 2100. However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere
An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming will be strongest in the Arctic and will be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include increases in the intensity of extreme weather events, species extinctions, and changes in agricultural yields.
Political and public debate continues regarding global warming, and what actions if any to take in response. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
Recycling involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution from incineration and water pollution from landfilling by reducing the need for conventional waste disposal, and lower greenhouse gas emissions as compared to virgin production.Recycling is a key component of modern waste reduction and is the third component of the
Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste – such as food or garden waste – is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing

The show's creators Ryan Murphy, Brad Falchuk, and Ian Brennan first conceived of Glee as a film. Murphy selects the series' music, maintaining a balance between show tunes and chart hits. Songs covered in the show are released on iTunes during the week of broadcast, and a series of Glee albums will be released through Columbia Records, beginning with Glee: The Music, Volume 1, which was released on November 3, 2009. The music of Glee has been a commercial success, with over two million digital sales.
Critical response to the show has been generally positive. Alessandra Stanley in The New York Times highlighted thepilot episode'sunoriginality and stereotyped characters, but praised the showmanship and talent of the cast.David Hinckley in The Daily News opined that the show was imperfect and implausible but "potentially heartwarming",while Robert Bianco in USA Today noted casting and tone problems, but commented positively on the show's humor and musical performances.Mary McNamara for the Los Angeles Times wrote that the show had a wide audience appeal, calling it "the first show in a long time that's just plain full-throttle, no-guilty-pleasure-rationalizations-necessary fun."The series was nominated for four 2010 Golden Globe Awards including, Best Comedy Series, Best Actress (Lea Michele), Best Actor (Matthew Morrison), and Best Supporting Actress (Jane Lynch).

This is a close call between Jordan and LeBron, but I will have to go with LeBron. LeBron is simply a beast who can score at anytime, but he is not that selfish. He is only 23 or so years old and already has numerous triple doubles and is in the top 100 scoreres in NBA history. When his career is over, he will have many championships, have been the #1 scorer in the NBA, and would have been considered the best NBA player of all time.
Michael Jordan! LeBron James may be the best around at the moment, however, Jordan is arguably the greatest ever! I think to compare them today is hugely premature.
With all his potential, Lebron James may indeed become a player of Jordanesque stature in a few years; although, Istress, I is far too early to make such a debate.
The bottom line is Michael Jordan, Kobe Bryant and Lebron James are the 3 greatest players to ever live.
The main reason some people think this is (aside from the fact that they're extremely gullible) the ancient Mayan calendar essentially resets in December of 2012. Now, you might be asking yourself: "So what?" Congratulations, this is the sane response. There's no reason to believe that it will be any more significant than January 1, 2000 (in fact, since nobody still uses the Mayan calendar, there's good reason to believe it will be much less significant). After all, does a car fall apart the instant the odometer rolls over? Particularly if it's some weird aftermarket odometer that measures in furlongs or something that hardly anyone uses anymore? The Mayans themselves don't seem to have been particularly concerned by it, since there are inscriptions indicating that the anniversaries of certain events would occur on dates even further in the future than 2012: a bit odd if they really thought the world would end in 2012. If the Maya had predicted the end 300 years ago, that would have been a lot more impressive, since for their culture it more or less did. However, most predictions have to do with numbers. Writing the numbers out you get 12 21, 2012. If the world were to end as to someones prediction, it should make numerical sense. Writing it out 21 12 2112 would make more sense. It is very unlikely we will all die in 2012.
