But that effect was offset by warming-associated drought that limited growth in the Southern Hemisphere, resulting in a net global loss of land productivity.

但是，这种积极影响被气候变暖带来的干旱所抵消，限制了南半球的植物生长，导致全球土地生产力出现负增长。

Scambos explains that, although the Northern Hemisphere experienced significant snowfall in early 2010, spring melt was rapid, exposing land surfaces to sunlight sooner than usual.

Scambos解释说。 虽然2010年初北半球经历了一场罕见的降雪，但春雪消融还是十分迅速，使地表比往常更早地暴露在阳光之下。

Seventy-four percent of those islands are found in the northern hemisphere, though that is not necessarily a surprise because roughly two-thirds of the world's land mass lies north of the equator.

在北半球发现了其中74%的岛屿，但这不足为奇，因为世界上2/3的岛群都在赤道北部。

For a number of reasons, computer models with added atmospheric carbon dioxide preferentially warm the mid-and high-latitude land areas of the northern hemisphere that are ice-free, which also enhances summer melting of the relatively shallow ice in the Arctic Ocean.
