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.
The move comes after regional authorities declared a state of emergency over the weekend after sightings of more than 50 bears in the town of Belushya Guba since December.
This year's letter from Bill and Melinda Gates focused on nine things that surprised them. For the Microsoft-cofounder, one thing he was surprised to learn was the massive amount of new buildings the planet should expect in the coming decades due to urban population growth.
"The number of buildings in the world is going to double by 2060. It's like we're going to build a new New York City every month for the next 40 years," he said.

After a dearth of action on climate change and a record year of extreme events in 2017, the inclusion of climate change policies within the annual legislation Congress considers to outline its defense spending priorities (the National Defense Authorization Act) for fiscal year 2018 was welcome progress. House and Senate leaders pushed to include language that mandated that the Department of Defense (DoD) incorporate climate change in their facility planning (see more on what this section of the bill does here and here) as well as issue a report on the impacts of climate change on military installations. Unfortunately, what DoD produced fell far short of what was mandated.
Trump is losing his rallying cry to save coal. The Tennessee Valley Authority (TVA) voted on Thursday to retire two coal-fired power plants in the next few years despite a plea from the president to keep one of the plants open.
Earlier this week, the president posted an oddly specific tweet that urged the government-owned utility to save the 49-year-old Paradise 3 plant in Kentucky. It so happens that the facility burns coal supplied by Murray Energy Corporation, whose CEO is Robert Murray, is a major Trump donor.
