Global Warming Expected to Intensify Hurricanes

DoraLives writes "Think this hurricane season was bad? Well according to the New York Times, a study was published online on Tuesday by The Journal of Climate indicating that warming ocean temperatures are going to make for stronger, wetter hurricanes in the coming years and decades. An abstract of the article concludes cheerfully enough that 'greenhouse gas-induced warming may lead to a gradually increasing risk in the occurrence of highly destructive category-5 storms.' Oh joy."

      CO2 emissions will likely increase over the next few decades, unless the countries that produce the most CO2 will start taking drastic action. That means the US, and to some extent, Europe and China. The 1% figure is about right.

      The ULEV vehicles you trash actually eliminate far worse greenhouse gases. Methane, for example, is 100x as potent a greenhouse gas as CO2, and the advanced catalysts do eliminate almost all the hydrocarbons (like methane) from the exhaust.

      CO2 concent rations in the atmosphere have increased by about 30 percent in the last 50 years, with most of the increase happening in the last few decades.

      The actual growth of CO2 varies from year to year, but has averaged about 0.5% per year for the last 15 years, with about 0.9% per year rates in the last four years (but these are probably related to El Nino cycles).

      China's rapid industrialization (fuelled mostly by coal---the fuel richest in carbon emissions) threatens to accelerate this growth rate for the next several decades, so 1% annual growth is quite a reasonable estimate.

      The key point is that they are less than 50% accurate for short term forcasts. The same rule applies to psychology for diagnosing a single patient (meaning that it isn't always particularly effective).

      This rule does not apply for large sums. Psychology, for example, is an extremely predictable science for sample sizes greater than 1000 or so. The same will apply to weather forcasts. And it makes complete sense since hurricanes are fueled by thermal energy. Increasing the overall thermal energy of the planet can only make them more probable.

In fact, when I saw this headline, I went looking for another story I saw just a few days ago that says that this may be part of a normal cycle of increasing and decreasing cyclone counts and intensities. It doesn't rule out global warming effects, but it does present an alternate theory.

      I have seen some other alternate theories to cover possible issues with global warming. Increases in geothermal activity under Greenland, for example, causing increased movement of the glaciers there. There's been the suggestion that increased energy output by the sun (a fraction of a percent, but at the level of the sun's output, that adds up pretty quickly) may be more at fault than man-made atmospheric releases. I don't mind research into man-made effects -- I'm all for getting off of oil dependency, and tech innovations are Very Good Things(TM) in general -- but alternate ideas do need to be suggested, considered, and explored.

    With the way people are blaming everything else in the world on Bush.. I'm surprised.

    Bush is getting part of the blame for it, and rightfully so. President Bush and his advisers maintain that reducing emissions through costly near-term measures is unjustified. The White House argues that forecasting climate change is too imprecise to agree to long-term, international, mandatory cuts in greenhouse gas emissions.

    In April of 2001, ten of the world's most prominent citizens wrote a letter (published in Time magazine) urging President George W. Bush to reduce the amount of greenhouse gas produced by the United States. Signatories included Stephen Hawking, Jimmy Carter, Mikhail Gorbachev, Senator John Glenn, Walter Cronkite, George Soros, and Jane Goodall. The letter was initiated by Charles Alexander, environment editor of "Time," while he was collaborating on the magazine's project to explore the scientific evidence for the existence and extent of global warming and the political furor over Bush's withdrawal of U.S. support for the Kyoto climate protocol after nine years of international negotiations.

Unfortunately, there are things we don't understand; our computer models don't explain all historical climate changes (even though every model has more C02 = climate change). And who knows, maybe the sun is hotter (even though the evidence for this is sketchier than any of the other data).
