Greenhouse gas emissions from methane, which largely originates from natural gas production and agriculture, have been underestimated by 25% to 40% compared to recent gauges, per a new study in the peer-reviewed journal Nature.

Why it matters: Methane gas is more potent than CO2 at trapping heat on a pound-for-pound basis in the short-term, which makes it an important factor to weigh as countries tackle global warming.

What they found: Ancient samples of air from Greenland's ice sheets contained "very little of the oldest type of methane — multimillion-year-old fossil methane gas," the Washington Post reports. This suggests that the Earth's current methane-addled atmosphere is caused by humans exploiting fossil fuels.

What they're saying: Harvard atmospheric scientist and methane expert Daniel Jacob told the Post that the study represented an “important result, because the current estimates for the methane geological source were widely considered too high by atmospheric modelers such as myself.”

  • Yes, but: Jacob told the Post that he disagreed with the study's inference that smaller fossil methane sources means that humans should increase emissions from another source.

Hiroshima mayor warns of rise of nationalism on 75th anniversary

Hiroshima's Mayor Kazumi Matsui on Thursday urged the international community to work together to defeat the coronavirus pandemic and warned against an increase in "self-centered nationalism," per the Washington Post.

Why it matters: He said at a remembrance service on the atomic bombing of the Japanese city that the 1918 flu pandemic killed millions as countries fighting in World War I were unable to overcome the threat together, per DPR. "A subsequent upsurge in nationalism led to World War II," he added. The U.S. bombing of Hiroshima on Aug. 6, 1945 and Nagasaki three days later contributed to the end of World War II, but tens of thousands of people died. At the service, Prime Minister Shinzo Abe lamented nuclear weapons' "inhumanity," but he didn't mention Japan's wartime past, WashPost noted.

LeBron James on Trump NBA protest remarks: "We could care less"

LeBron James responded on Wednesday night to President Trump's comments calling NBA players "disgraceful" for kneeling during the national anthem to protest racism and that he won't watch games because of the action.

The big picture: Trump has repeatedly criticized sports players for taking the knee since 2016. But James said during a news conference, "I really don’t think the basketball community are sad about losing his viewership, him viewing the game." November's elections marked "a big moment for us as Americans," he said. "If we continue to talk about, 'We want better, we want change,' we have an opportunity to do that," he added. NBA Commissioner Adam Silver has said the league will "respect peaceful protest."
