: 報告說，自50年代到2000年所觀察到的氣候變化是「前所未有的」。
: 過去30年中，每10年的地表溫度都在持續變暖，比1850年以來的任何時期溫度都更高，很
: 可能比過去1400年的任何時候都更溫暖。
: 政府間氣候變化專門委員會第一工作組聯合主席秦大河說， 工作小組的科學研究發現，
: 地球的大氣和海洋都在變暖。而地球的冰雪正在消失， 全球平均海平面也在上升。 同時

IPCC climate report: humans 'dominant cause' of warming

However, the report does alter a key figure from the 2007 study. The
temperature range given for a doubling of CO2 in the atmosphere, called
equilibrium climate sensitivity, was 2.0C to 4.5C in that report.
In the latest document, the range has been changed to 1.5C to 4.5C. The
scientists say this reflects improved understanding, better temperature
records and new estimates for the factors driving up temperatures.
In the summary for policymakers, the scientists say that sea level rise will
proceed at a faster rate than we have experienced over the past 40 years.
Waters are expected to rise, the document says, by between 26cm (at the low
end) and 82cm (at the high end), depending on the greenhouse emissions path
this century.
The scientists say ocean warming dominates the increase in energy stored in
the climate system, accounting for 90% of energy accumulated between 1971 and
2010.
For the future, the report states that warming is projected to continue under
all scenarios. Model simulations indicate that global surface temperature
change by the end of the 21st Century is likely to exceed 1.5 degrees
Celsius, relative to 1850.
如果把1.5度溫度變化集中在海洋這水體裡, 地球的循環會有何變化?
