A long-awaited five-year United Nations climate report, to be released later this week, is expected to be the most dire yet, as well as the most conclusive about a human link to warming. The study reportedly cites a 90 percent probability that human activities are to blame for most of the warming trend of the past half-century.
But some top scientists are saying the report isn’t dire enough, and doesn’t take into account recent major melting events with arctic ice, which some think could mean flooded coastlines much earlier than previously thought.
