Check out this animation. Notice that the heating our continent will experience is by far greatest in and from the north. (sorry for the horrible embedded ad)
Researchers at NASA's Goddard Space Flight Center teamed with scientists at the National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC) in Asheville, N.C., to create a new video, which compares two different climate change scenarios: One in which atmospheric carbon dioxide levels increase from today's level of 400 parts per million to 550 ppm, and a second in which carbon dioxide levels double to 800 ppm. (Parts per million means that, for example, for every million molecules of air, 400 of them are carbon dioxide.)
These carbon dioxide concentrations are based on high- and low-emissions scenarios proposed by the Intergovernmental Panel on Climate Change, and are based on a variety of factors, including potential world population growth, economic development and global commitment to sustainability. The first scenario would require some kind of mitigation and curtailment of greenhouse gas emissions, while the second would occur if emissions continued to increase.
Put another way, the 550 ppm projection is the "best case" scenario that we might hope for but only if we act to mitigate the damage by slashing our greenhouse gas emissions. Failing that, you've chosen Option "B". Your choice.
A report from the U.S. Energy Information Administration forecasts a 56% growth in energy consumption by 2040 with fossil fuels still dominating.
“Rising prosperity in China and India is a major factor in the outlook
for global energy demand. These two countries combined account for half
the world’s total increase in energy use through 2040,” said EIA
administrator Adam Sieminski in a press release. The EIA is the
Department of Energy’s statistical and analytical agency.
Energy use in developing countries, for example, is projected to
increase by 90 percent by 2040, while industrialized nations will see a
comparatively paltry increase of 17 percent. By 2040, China's energy
demand is expected to be twice that of the U.S., the report projected.
So, with that happy news you might want to reconsider the two scenarios presented by NASA to decide which you think the most likely.
