World scientists – we can’t raise the temperature by more than two degrees Celsius

The official position of planet Earth at the moment is that we can’t raise the temperature more than two degrees Celsius.

Some context: So far, we’ve raised the average temperature of the planet just under 0.8 degrees Celsius, and that has caused far more damage than most scientists expected. (A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)

Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees.

We’re not getting any free lunch from the world’s economies, either. With only a single year’s lull in 2009 at the height of the financial crisis, we’ve continued to pour record amounts of carbon into the atmosphere, year after year. In late May, the International Energy Agency published its latest figures – CO2 emissions last year rose to 31.6 gigatons, up 3.2 percent from the year before.

  • America had a warm winter and converted more coal-fired power plants to natural gas, so its emissions fell slightly
  • China kept booming, so its carbon output (which recently surpassed the U.S.) rose 9.3 percent
  • Japanese shut down their fleet of nukes post-Fukushima, so their emissions edged up 2.4 percent.

Coal power plants are going offline, in favor of Natural Gas plants

“In the past year, coal plants have been facing a perfect storm of falling natural gas prices, a continued trend of high coal prices and weak demand for electricity,” Susan Tierney wrote in the report.

Tierney wrote that those factors have combined to make coal a less desirable fuel source.

Coal-generated electricity has been waning over the past few years, dropping to its lowest level on record in March of this year, according to the U.S. Energy Information Administration.

At the same time, natural gas-powered plants are becoming increasingly popular as the price of the fuel falls to record prices and few emissions emitted by natural gas.

According to Doyle Trading Consultants, the trend is expected to continue as more than 41,000 megawatts from coal-fired power plants could be retired by 2020. If true, the coal-fired fleet would be cut by 17 percent in eight years.
