Sentences with phrase «ice cores demonstrate»

Although ice cores demonstrate that climate, in the distant past, sometimes changed very abruptly, future temperatures resulting from our current emissions course will likely exceed anything ever experienced by humans.

This paper, cosignated by Bard as last author, seems to be the paper too much, too much, trop trop trop for him; it has a smell of pine tree (or coffin) as that of the «scientific» carrier of M.Mann It looks a bit bizarre to me that it would be revolutionnary that temperatures of Northern Atlantic and tropical environments do not lag that of polar environments and ice, while the sun irradiates more the poles to the detriment of tropical latitudes; really, as long, as they do not demonstrate that CO2 does not lag temperature in ice cores, there is nothing new; and if they do, we are waiting for the explanations of vice président Jouzel to find the source of CO2 before the deep polar oceans started to moove
