global warming news - Report: The Case for Global Warming Stronger Than Ever - TIME

By looking at a wide range of observations from all over the world, the Met Office study concludes that the fingerprint of human influence on climate is stronger than ever. Plenty of these climate effects had already been observed at the time of the 2007 IPCC report, including warming temperatures, shifts in rainfall (wet regions getting wetter, dry regions getting drier) and the increase in summer meltback of Arctic sea ice. Add the greenhouse gases that we know humans are generating (and which we've known since the 1800s tend to warm the Earth, all other things being equal), and the simulations finally come close to matching the real world. Secretary General Ban Ki-moon announced that an independent panel of scientists, representing national science academies from around the world, would review the IPCC's research procedures — an effort to account for the 2007 report's mistakes, for which the IPCC has come under hard criticism. The fact that climate change evidence that was "very likely" a few years ago has now been declared likelier still by the comprehensive Met Office report suggests that the evidence for human-caused climate change is getting better all the time.
