A United Nations panel said it is more certain than ever humans are a dominant cause of global warming and predicted temperatures would continue to rise this century.

联合国政府间气候变化小组说，该组织比以往任何时候都更加确信人类活动是造成全球气候变暖的主要原因。该组织预测，全球气温将在本世纪继续上升。

The Intergovernmental Panel on Climate Change said Friday it is "extremely likely", its strongest words yet, that humans are largely responsible for global warming.

联合国政府间气候变化小组在星期五的报告中用迄今为止最强烈的措辞指出，人类活动“极有可能”造成了气候变暖。

In its last report in 2007, IPCC said it was "very likely" global warming was man-made.

在2007年的报告中，该小组曾表示气候暖化“很有可能”是人为因素造成的。

The co-chair of the group that wrote the new report said it has found that the atmosphere and ocean have warmed, snow and ice have diminished, the global mean sea level has risen and the concentration of greenhouse gases has increased.

报告的主要撰写人表示，报告发现全球大气和海洋温度仍在上升，地球冰雪消融，海平面持续升高，大气层温室气体浓度在增加。

The U.N. panel predicted that global average temperatures would rise by 0.3 to 4.8 degrees Celsius by 2100 with sea levels rising by 26 to 82 centimeters.

联合国政府间气候变化小组预计，2100年前，地球平均温度将升高0点3到4点8摄氏度，海平面将升高26至82厘米。
