Dalla rassegna quotidiana di Science Daily di giovedì scorso. Per dilettare il vostro week end, qualora mai aveste deciso di trascorrerlo senza un po’ di sana contrizione, di consapevolezza elle vostre colpe e di fiducia nei salvatori della patria.
New research indicates that Atlantic Ocean temperatures during the greenhouse climate of the Late Cretaceous Epoch were influenced by circulation in the deep ocean. These changes in circulation patterns 70 million years ago could help scientists understand the consequences of modern increases in greenhouse gases.
Governments around the world must be prepared for mass migrations caused by rising global temperatures or face the possibility of calamitous results, say scientists.
Climate scientists say the world’s target to stay below a global warming of 2 degrees, made at the United Nations conference in Copenhagen in 2009 and Cancun 2010 will require decisive action this decade.
A new analysis of climate change data and the effects of rising levels of the greenhouse gas carbon dioxides suggests that we are at the end of the period in Earth’s history during which icy glaciers form. The study further suggests that the effects of rising CO2 levels is delayed by as much as 50 years, but global average temperature might be as much as 5 degrees higher than it is today by the year 2100.
