Carbon dioxide emissions are on track to rise in 2018 for the second straight year following a plateau in 2014-2016, according to the International Energy Agency.

Why it matters: IEA's finding arrived as a United Nations science panel unveiled a major report concluding that large emissions cuts are needed in coming years to hold global warming to 1.5 degrees Celsius above preindustrial levels.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

By the numbers: According to the UN's analysis, staying within the 1.5°C target — a benchmark for avoiding far more severe consequences than are already occurring — means human-induced CO2 emissions must fall by 45% by 2030 and reach "net zero" by mid-century.

  • The 45% cut is relative to 2010 levels, which in effect means even deeper reductions are needed.

The big picture: Separate analyses in recent months have shown that energy-related CO2 emissions — that is, the vast majority of global CO2 — ticked up again in 2017 after a multi-year plateau.

IEA's new 2018 projection underscores how the global energy system is far, far off track from the gigantic and rapid transformation that the UN's deeply researched analysis calls needed to stay within the 1.5°C target.

  • "The world is not moving towards Paris Agreement goals requiring emissions to peak as soon as possible, but away from them," IEA Executive Director Fatih Birol said via Twitter.

The bottom line: As Axios' Andrew Freedman wrote, global warming will have far more severe consequences if temperatures are allowed to creep past 1.5°C, or 2.7°F, of warming, scientists concluded in the UN analysis.

They noted that there are already deadly impacts from the 1°C, or 1.8°F, of warming so far — including more severe and longer lasting heat waves, more heavy precipitation events, and ocean warming that is killing many of the planet's coral reefs.

Omicron pushes COVID deaths toward 2,000 per day

The U.S. Omicron wave may be peaking, but now COVID deaths are climbing as cases continue to soar in most of the country.

The big picture: Omicron’s stranglehold in the U.S. started about a month ago. Its death toll — while almost certain to be smaller than previous waves of the pandemic — is only now starting to take hold, and deaths will likely continue to rise for several weeks.

Tax season nightmare ahead for understaffed IRS

The IRS will start accepting 2021 tax returns in less than a week, and the filing delays and administrative headaches to come might eclipse last year — which was “one of the worst filing seasons," according to an independent advocacy agency within the IRS.

Why it matters: For taxpayers, especially with complex or paper filings, this means headaches, delayed refunds, and mistakes.

Reports: CIA finds "Havana Syndrome" unlikely caused by foreign campaign

A preliminary CIA report rules out a foreign global campaign as the cause of a mysterious illness known as "Havana syndrome" that's afflicted American and Canadian diplomats around the world, per multiple reports.

Why it matters: Some lawmakers had suggested the sometimes debilitating illness was due to directed energy attacks. But CIA officials told the New York Times that most of the 1,000 cases reported to the government could be "explained by environmental causes, undiagnosed medical conditions or stress." This finding has angered some victims, per the NYT.
