OSLO (Reuters) – Global warming is on track to breach the toughest limit set in the Paris climate agreement by the middle of this century unless governments make unprecedented economic shifts from fossil fuels, a draft U.N. report said.

The draft, of a report due for publication in October, said governments will also have to start sucking carbon dioxide from the air to achieve the ambition of limiting temperatures to 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial times.

“There is very high risk that … global warming will exceed 1.5 degrees Celsius above pre-industrial levels,” the U.N. panel of experts wrote, based on the current pace of warming and current national plans to limit their greenhouse gas emissions.

There were no historic precedents for the scale of changes required in energy use, to shift from fossil fuels to renewable energies, and in reforms ranging from agriculture to industry to stay below the 1.5C limit, it said.

The draft, by the U.N.’s Intergovernmental Panel on Climate Change (IPCC) of leading scientists and obtained by Reuters, says average surface temperatures are about 1C above pre-industrial times and that average temperatures are on track to reach 1.5C by the 2040s.

Curbing warming to 1.5C would help limit heat extremes, droughts, and floods, more migration of people, and even risks of conflict compared to higher rates of warming, according to the draft summary for policymakers.

But a 1.5C rise might not be enough to protect many coral reefs, already suffering from higher ocean temperatures, and ice stored in Greenland and West Antarctica whose melt is raising sea levels. [more]

Warming set to breach Paris accord's toughest limit by mid century: draft

    Sorry, but these kinds of disingenuous stories and articles are misleading and inaccurate. There are already plenty of places on the planet where warming has already exceeded 1.5C. The associated disruptions have been well documented.

    Yes, it did say "global" but taking the world's "average temperature" misses the massive heat buildup that is occurring (especially in the world's oceans).

    Moreover, mankind's ability to "suck the C02" out of the atmosphere is vaporware - it does not exist. Maybe it will in 2050 - or maybe it won't, but it's very likely that by then, it will be much too late anyway. It has been demonstrated several times that we lack the resources, energy and infrastructure to do this too.

    The problem is actually considered physically impossible now - I can't imagine that 30 more years would magically make it feasible.

    Wow, that is one of the worst articles I have seen this great site post. Even the oil giants admit that 5C is baked in by mid century.
