Most of those planets are more massive than Saturn, which makes them unpromising from a habitability standpoint-such giants tend to be gaseous bodies without a surface to walk on.
汉森在报告中声称：“如果气温任像预期的那样攀升，温室气体继续增加，那么新的最高记录将会很快产生。”
Hansen states in the report, "if the warming trend continues, as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long."
像HFC-134a（化学名称为:1，1，1，2——四氟乙烷）之类的却非如此角色。这种各工业所使用的气体的排放物致使全球变暖的程度比起二氧化碳的要高出1000多倍，大量排出则造成大量污染。
The same is not true for, say, HFC-134a, a gas with various industrial uses that delivers more than 1,000 times more warming than carbon dioxide, mass for mass.
