12-06-12 Although it's long been suspected that human activity has greatly contributed to environmental stress, it's only recently that science has begun to show just how great a role that activity is playing. In an article published in the journal Nature Cl...

12-06-12 The oceans have warmed in the past 50 years, but not by natural events alone. New research by a team of Lawrence Livermore National Laboratory scientists and international collaborators shows that the observed ocean warming over the last 50 years is...

12-06-07 Mexican President Felipe Calderon has signed a law introducing binding targets on climate change. 墨西哥总统费利佩卡尔德隆将一份气候变化约束力目标的法案签署生效。 Mr Calderon said on Twitter that the law would make Mexico the first developing countr...

12-06-07 A geoengineering solution to climate change could lead to significant rainfall reduction in Europe and North America, a team of European scientists concludes. The researchers studied how models of Earth in a warm, CO2-rich world respond to an artifi...

12-05-22 A clear change in salinity（盐度） has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation（蒸发，消失） cycle. In a paper just published in the journal Science, Australian scientists fro...

12-05-21 In the first study of its kind in Australasia, scientists have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1000 years. The study was led by researchers at the University of...

12-05-16 For the first time, researchers have been able to combine different climate models using spatial（空间的） statistics -- to project future seasonal temperature changes in regions across North America. They performed advanced statistical analysis on...

12-05-08 Sauropod（蜥脚类动物） dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when Earth was warm and wet. That's according to calculations reported in the May 8th is...

12-05-04 In classical mythology（神话） , the cypress（柏树） tree is associated with death, the underworld and eternity. Indeed, the family to which cypresses belong, is an ancient lineage of conifers（松柏类） , and a new study of their evolution affords a...

12-05-04 Experiments may dramatically underestimate how plants will respond to climate change in the future. That's the conclusion of an analysis of 50 plant studies on four continents, published this week in an advance online issue of the journal Nature, wh...
