Global Warming to Exceed 1.5°C Threshold by 2040, UN Draft Report Warns
A final draft report from the United Nations' Intergovernmental Panel on Climate Change (IPCC) says only "rapid and far-reaching" changes in the world economy can keep global warming below the internationally agreed target barrier.
"If emissions continue at their present rate, human-induced warming will exceed 1.5°C by around 2040," the draft states, according to Reuters, which obtained a copy of the report.
The report, dated June 4, is due for publication in October at the 48th Session of the IPCC in South Korea after revisions and approval by governments. The document will be the main scientific guide to stave off disastrous climate change.
The 2015 Paris agreement, signed by 197 countries, sets a warming limit of "well below 2°C" over pre-Industrial Revolution levels with an aspirational 1.5°C target to avoid dangerous climate effects such as sea level rise, extreme weather and droughts.
In January, a leak of an earlier draft suggested a "very high risk" the 1.5°C target will be surpassed by mid-century. The current draft reaffirms the findings of the earlier draft, but also includes 25,000 comments from experts and a wider pool of scientific literature, Reuters noted.
The latest news further cements worldwide failure to meet the goals struck in Paris. Last year's Emissions Gap Report from the UN's environment program found that greenhouse gas emissions are set to overshoot the climate accord by about 30 percent. National pledges only covered a third of the cuts needed by 2030 to avoid the worst impacts of climate change.
Annual emissions are likely to hit 53.0-55.5 billion tonnes of carbon dioxide equivalent, which greatly exceeds the 42 billion ton threshold for avoiding the 2°C temperature rise, the report found. Notably, even if the national pledges are fully implemented, it is "very likely" global average temperature increase will be at least 3°C by 2100.
"Should the United States follow through with its stated intention to leave the Paris Agreement in 2020, the picture could become even bleaker," the Emissions Gap Report pointed out, referring to President Donald Trump's controversial withdrawal from the Paris agreement. The U.S. is one of the world's largest single emitters of greenhouse gases.

Ethics investigations have been opened into the conduct of senior Trump appointees at the nation's top environmental agencies.
The two investigations focus on Environmental Protection Agency (EPA) Administrator Andrew Wheeler and six high-ranking officials in the Department of Interior (DOI), The Hill reported Tuesday. Both of them involve the officials' former clients or employers.
"This is demonstrative of the failures at the very top of this administration to set an ethical tone," Campaign Legal Center Ethics Counsel Delaney Marsco told The Washington Post of the DOI investigation. "When people come to work for government, they're supposed to work on behalf of the public. It's a betrayal of the public trust when senior political appointees seem to give privileged access to their former employers or former clients."

We've known for more than 50 years that smoking cigarettes comes with health hazards, but it turns out those discarded butts are harmful for the environment, too. Filtered cigarette butts, although small, contain dozens of chemicals, including arsenic and benzene. These toxins can leach into the ground or water, creating a potentially deadly situation for nearby birds, fish and other wildlife.

Five years ago this week, an emergency manager appointed by then-Michigan Gov. Rick Snyder made the devastating decision to save money by switching Flint's water supply over from Detroit's water system to the Flint River. Seen as a temporary fix, the new water supply was not properly treated. High levels of lead leached from the old pipes, poisoning a generation of Flint's children, and bacteria responsible for an outbreak of Legionnaires' Disease killed more than a dozen residents.
Did you know that more than a third of food is wasted or thrown away every year? And that only 25 percent of it would be enough to feed the 795 million undernourished people in the world? That's why today is Stop Food Waste Day, a chance to reflect on what you can do to waste less of the food you buy.
