A leading US team of climate researchers on Friday released “the most compelling evidence yet” that human activities are responsible for global warming. They said their analysis should “wipe out” claims by sceptics that recent warming is due to non-human factors such as natural fluctuations in climate or variations in solar or volcanic activity.
Scientists from the Scripps Institution of Oceanography in California have been working for several years with colleagues at Lawrence Livermore National Laboratory to analyse the effects of global warming on the oceans. They combined computer modelling with millions of temperature and salinity readings, taken around the world at different depths over five decades.
