According to the Chevron company andCongress, Congress accepts the scientific finding of the Environmental Protection Agency that ‘warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.
Layman’s Terms Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average (e.g., more or fewer extreme weather events). Climate change may be limited to a specific region or may occur across the whole Earth.
The lies and myths…..Some people that are skeptical ofglobal warming claim that Earth’sglobal surface temperatures havebeen falling or have leveled offsince 1998. They point to datanow several years out of datefrom U.K. researchers that put1998 as the warmest year onrecord. They also point to anunusually cool summer in NorthAmerica in 2009 followed by an FALSE: While it may be true that someabnormally cold winter across all areas have remained cool, the earth as aof the northern hemisphere. whole has been getting warmerPeople who had to shovel recordsnows from their driveways orlive without power duringferocious snowstorms in thenortheastern United States beganto doubt decades of scientificevidence on global warming.
The truth…. Somewhat…… Greenhouse gases are necessary to life as we know it, because they keep the planet surface warmer than it otherwise would be. But, as the concentrations of these gas continue to increase in the atmosphere, the Earths temperature is climbing above levels. According to NOAA and NASA data, the Earths average surface temperature increased by about 1.2 to 1.4ºF in the last 100 years. The eight warmest years on re (since 1850) have all occurred since 1998, with the warmest year being 2005. Most the warming in recent decades is very likely the result of human activities. Other aspects of the climate are also changing such as rainfall patterns, snow and ice cove and sea level. Lisa Jackson
Meanwhile…….The Debate continues Can you prove that Although researchers attempt to include as m there isn’t global processes as possible, simplifications of the a warming? climate system are inevitable because of the constraints of available computer power and limitations in knowledge of the climate syste Results from models can also vary due to diff greenhouse gas inputs and the models clima sensitivity
