The latest IPCC report on climate change provides an assessment of the natural, ecological, social and economic impacts unfolding as global warming increases. It looks at the interrelationship between nature and human society, the certainty that human activity is responsible for global warming, and the consequences of inaction to date. Part 1 of 2 discusses our inadequate and insufficient response to addressing adaptation and how warming in the natural world has potential consequences that go beyond climate change's human impact.Â
