“#Global warming is likely to blow past Paris limit<\/strong>”<\/p>\n

\n

Earth\u2019s climate is getting so hot that temperatures in about a decade will probably blow past a level of warming that world leaders have sought to prevent, according to a report released Monday that the United Nations calls a \u201ccode red for humanity.\u201d<\/p>\n

\u201cIt\u2019s just guaranteed that it\u2019s going to get worse,\u201d said report co-author Linda Mearns, a senior climate scientist at the U.S. National Center for Atmospheric Research. \u201cI don\u2019t see any area that is safe \u2026 Nowhere to run, nowhere to hide.\u201d<\/p>\n

But scientists also eased back a bit on the likelihood of the absolute worst climate catastrophes.<\/p>\n

The authoritative\u00a0Intergovernmental Panel on Climate Change (IPCC)<\/a>\u00a0report, which calls climate change clearly human-caused and \u201cunequivocal,\u201d makes more precise and warmer forecasts for the 21st century than it did last time it was issued\u00a0in 2013<\/a>.<\/p>\n

Each of five scenarios for the future, based on how much carbon emissions are cut, passes the more stringent of two thresholds set in the\u00a02015 Paris climate agreement<\/a>. World leaders agreed then to try to limit warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since the late 19th century because problems mount quickly after that. The limit is only a few tenths of a degree hotter than now because the world has already warmed nearly 1.1 degrees Celsius (2 degrees Fahrenheit) in the past century and a half.<\/p>\n

Under each scenario, the report said, the world will cross the 1.5 degrees Celsius warming mark in the 2030s, earlier than some past predictions. Warming\u00a0has ramped up<\/a>\u00a0in recent years, data shows.<\/p>\n

In three scenarios, the world will also likely exceed 2 degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial times \u2014 the other, less stringent Paris goal \u2014 with far worse heat waves, droughts and flood-inducing downpours \u201cunless deep reductions in carbon dioxide and other greenhouse gas emissions occur in the coming decades,\u201d the report said.<\/p>\n

\u201cThis report tells us that recent changes in the climate are widespread, rapid and intensifying, unprecedented in thousands of years,\u201d said IPCC Vice Chair Ko Barrett, senior climate adviser for the U.S. National Oceanic and Atmospheric Administration. \u201cThe changes we experience will increase with further warming.\u201d<\/p>\n

The 3,000-plus-page report\u00a0from 234 scientists\u00a0<\/a>said warming is already accelerating sea level rise, shrinking ice and worsening extremes such as heat waves, droughts, floods and storms. Tropical cyclones are getting stronger and wetter, while Arctic sea ice is dwindling in the summer and permafrost is thawing. All of these trends will get worse, the report said.<\/p>\n

For example, the kind of heat wave that used to happen only once every 50 years now happens once a decade, and if the world warms another degree Celsius (1.8 degrees Fahrenheit), it will happen twice every seven years, the report said.<\/p>\n

As the planet warms, places will get hit more not just by extreme weather but by multiple climate disasters that occur simultaneously, the report said. That\u2019s like what\u2019s now happening in the\u00a0Western U.S., where heat waves, drought and wildfires compound the damage, Mearns said.<\/p>\n

Some harm from climate change \u2014 dwindling ice sheets, rising sea levels and changes in the oceans as they lose oxygen and become more acidic \u2014 are \u201cirreversible for centuries to millennia,\u201d the report said.<\/p>\n

The world is \u201clocked in\u201d to 15 to 30 centimeters (6 to 12 inches) of sea level rise by mid-century, said report co-author Bob Kopp of Rutgers University.<\/p>\n

Nearly all of the warming that has happened on Earth can be blamed on emissions of heat-trapping gases such as carbon dioxide and methane. At most, natural forces like the sun or simple randomness can explain one- or two-tenths of a degree of warming, the report said.<\/p>\n

The report described five different future scenarios based on how much the world reduces carbon emissions. They are: a future with incredibly large and quick pollution cuts; another with intense pollution cuts but not quite as massive; a scenario with moderate emissions; a fourth scenario where current plans to make small pollution reductions continue; and a fifth possible future involving continued increases in carbon pollution.<\/p>\n

In five previous reports, the world was on that final hottest path, often nicknamed \u201cbusiness as usual.\u201d But this time, the world is somewhere between the moderate emissions path and the small pollution reductions scenario because of progress to curb climate change, said report co-author Claudia Tebaldi, a scientist at the U.S. Pacific Northwest National Lab.<\/p>\n

In a way, the world can stay at the 1.5-degree threshold with extreme and quick emission cuts, but even then, warming would hit 1.5 degrees in a decade, rise a tad and then come back down, said co-author Maisia Rojas Corrada, director of the Center for Climate and Resilience Research in Chile.<\/p>\n

While calling the report \u201ca code red for humanity,\u201d United Nations Secretary-General<\/a> Antonio Guterres kept a sliver of hope that world leaders could still somehow prevent 1.5 degrees of warming, which he said is \u201cperilously close.\u201d<\/p>\n

\u201cAnything we can do to limit, to slow down, is going to pay off,\u201d Tebaldi said. \u201cAnd if we cannot get to 1.5, it\u2019s probably going to be painful, but it\u2019s better not to give up.\u201d<\/p>\n

In the report\u2019s worst-case scenario, the world could be around 3.3 degrees Celsius (5.9 degrees Fahrenheit) hotter than now by the end of the century. But that scenario looks increasingly unlikely, said report co-author and climate scientist Zeke Hausfather, climate change director of the Breakthrough Institute. Both extremes are looking less likely, he said.<\/p>\n

\u201cWe are a lot less likely to get lucky and end up with less warming than we thought. We won\u2019t be able to meet Paris Agreement goals without rapid near-term reductions in our emissions,\u201d Hausfather said. \u201cAt the same time, the odds of ending up in a much worse place than we expected if we do reduce our emissions are notably lower.\u201d<\/p>\n

The report said ultra-catastrophic disasters, commonly called \u201ctipping points,\u201d like ice sheet collapses and the abrupt slowdown of ocean currents are \u201clow likelihood\u201d but cannot be ruled out. The much talked-about shutdown of Atlantic ocean currents, which would trigger massive weather shifts, is something that\u2019s unlikely to happen in this century, Kopp said.<\/p>\n

The report \u201cprovides a strong sense of urgency to do even more,\u201d said Jane Lubchenco, the White House deputy science<\/a> adviser.<\/p>\n

In a new move, scientists emphasized how cutting airborne levels of methane, a powerful but short-lived gas that has soared to record levels, could help curb short-term warming.<\/p>\n

More\u00a0than 100 countries\u00a0have made informal pledges to achieve \u201cnet zero\u201d human-caused carbon dioxide emissions sometime around mid-century, which will be a key part of climate negotiations this fall in Scotland. The report said those commitments are essential.<\/p>\n

\u201cIt is still possible to forestall many of the most dire impacts,\u201d Barrett said.\n <\/p><\/div>\n
