    The planet is warming at a pace not experienced within the past 1,000 years, at least, making it “very unlikely” that the world will stay within a crucial temperature limit agreed by nations just last year, according to Nasa’s top climate scientist.
    This year has already seen scorching heat around the world, with the average global temperature peaking at 1.38C above levels experienced in the 19th century, perilously close to the 1.5C limit agreed in the landmark Paris climate accord. July was the warmest month since modern record keeping began in 1880, with each month since October 2015 setting a new high mark for heat.
    But Nasa said that records of temperature that go back far further, taken via analysis of ice cores and sediments, suggest that the warming of recent decades is out of step with any period over the past millennium.
    Gavin Schmidt, director of Nasa’s Goddard Institute for Space Studies adds that maintaining temperatures below the 1.5C guardrail requires significant and very rapid cuts in carbon dioxide emissions or co-ordinated geo-engineering, which is very unlikely, because we are not even yet making emissions cuts commensurate with keeping warming below 2C.

    This is a bigger problem than most take seriously. I hear all the time comments about the weather wherever i go from locals that the weather was not like this before growing up, its getting more unpredictable, hotter etc.

    Where i am right now, the weather has changed just in the last few years due to pollution and enough people noticed it to not be imagination. The depletion of the ozone is a real threat too.
