美國聯邦政府氣候變遷研究中心, 提出嚴重警告,　氣候災難是人類迫切必須共同面對的議題.

Extreme Weather More Common500-year floods and microbursts have only recently entered my vocabulary. Extreme weather events have entered our national consciousness, altered our landscape, and are currently changing our thinking about global warming. The U.S. Climate Change Science Program and the Subcommittee on Global Change Research recently released a scientific analysis of the extreme weather changes we can expect in the future. The study focuses on the U.S. specifically, and the related NOAA release provided six projections for the near future.
(1) It's Getting Hotter in HereAbnormally hot days and nights, along with heat waves, are very likely to become more common. Cold nights are very likely to become less common.
(2) Amazing Vanishing Sea IceSea ice extent is expected to continue to decrease and may even disappear in the Arctic Ocean in summer in coming decades.
(3) When it Rains, it PoursPrecipitation, on average, is likely to be less frequent but more intense.
(4) Hot & Dry in the South & WestDroughts are likely to become more frequent and severe in some regions.
(5) Wetter and Stronger StormsHurricanes will likely have increased precipitation and wind.
(6) More Damaging Winds and WavesThe strongest cold-season storms in the Atlantic and Pacific are likely to produce stronger winds and higher extreme wave heights.
The full report, 'Weather and Climate Extremes in a Changing Climate' is available at the U.S. Climate Change Science Program website. The table below (high res available) provides another way to quickly look at the predictions found in the report that are likely to continue throughout this century.
