    Updated 2 May 2013 to correct typo on date of previous low tornado countThe 12-month period from May 2012 to April 2013 was remarkable for the absence of tornado activity and tornado impacts in the United States.We can start by looking at the number of EF1 and stronger tornadoes during that period. A final count is available through January 2013 and we have a pretty good estimate of how many occurred in February through April, although final numbers won’t be available until July. Although the 12 month total may change a little bit with the final data, it’s unlikely to...

    In the war of dumb ideas, both liberals and some corporatist conservatives have joined forces for a pincer movement on rational citizens by promoting the spending of large amounts of taxpayer dollars to deal with climate change. Mitigation, of course, is the concept that humans are altering the planet's climate through greenhouse gas (GHG) emissions, and funds should be spent to reduce emissions and minimize anthropogenic climate change. Adaptation is the acceptance that the Earth's climate is changing, either from natural or anthropogenic forces (or both), and that rather than spend money trying to reduce man-made GHG emissions, it is...
  • Study Warns of Rapid Rise In Earth's Temperature

    A study warns that the Earth's temperature is approaching a level not seen in a million years, implying that we are getting close to "dangerous" levels of human pollution. The study finds that, while the world warmed slowly during the century to 1975, it has warmed at a more rapid rate of about 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade thereafter. The researchers say the global mean temperature is now within one degree Celsius (1.8 degrees Fahrenheit) of the maximum mean temperature of the past million years. Based on a 0.2-degree-Celsius increase per decade, that high point could be...
  • Evidence linking climate change to extreme weather mounts (hot air “mounts”)

    The world’s scientists are now more than 90% sure that human-caused global warming will increase the length, frequency and intensity of extreme weather events such as heat waves, the most authoritative scientific report yet on the subject says. The Intergovernmental Panel on Climate Change (IPCC) report into extreme weather events found with “high confidence” that climate change has already made heat waves more severe in areas including southern Europe and the Mediterranean. By 2100, the financial cost of extreme weather conditions could be some €15 trillion, mostly borne by what is currently the developing world. The worst affected will be...
  • Reports link heat waves, deluges to climate change

    Scientists are increasingly confident that the uptick in heat waves and heavier rainfall is linked to human-caused greenhouse gas emissions, posing a heightened risk to the world’s population, according to two reports issued in the past week. On Wednesday, the U.N. Intergovernmental Panel on Climate Change released a 594-page study suggesting that when it comes to weather observations since 1950 there has been a “change in some extremes,” which stem in part from global warming. [text excerpted] But the IPCC team projects that there is a 90 to 100 percent probability that sea level rise “will contribute to upward trends...
  • Extreme weather: Better models are needed before exceptional events can be reliably linked to...

    Better models are needed before exceptional events can be reliably linked to global warming. As climate change proceeds — which the record summer melt of Arctic sea-ice suggests it is doing at a worrying pace — nations, communities and individual citizens may begin to seek compensation for losses and damage arising from global warming. Climate scientists should be prepared for their skills one day to be probed in court. Whether there is a legal basis for such claims, such as that brought against the energy company ExxonMobil by the remote Alaskan community of Kivalina, which is facing coastal erosion and...
  • Wild weather can send greenhouse gases spiralling (There's no increase in extreme weather events.)

    Researchers get to grips with effects of heat, drought and storms on carbon release. Climate change has a disconcerting tendency to amplify itself through feedback effects. Melting sea ice exposes dark water, allowing the ocean to soak up more heat. Arctic warming speeds the release of carbon dioxide from permafrost. And, as researchers discussed at a meeting last week in Seefeld, Austria, climate extremes — heatwaves, droughts and storms — can hamper plant growth, weakening a major buffer against the rise of CO2 in the atmosphere. “Heatwaves and droughts will very likely become more frequent in a warmer climate, and...

    Pollution during the 20th century appears to have suppressed North Atlantic hurricanes The Clean Air Act, which has benefited breathing in many American cities over the last few decades, may have worsened the weather in some places. New climate simulations suggest that reducing the level of atmospheric aerosol particles produced by human activity might have been the main cause of a recent increase in tropical storm frequency in the North Atlantic. Aerosol levels have increased since the industrial revolution began, but there have been periods when emissions stalled or fell, such as the Great Depression, World War II and after...
