The World Will Overshoot 1.5°C and Must Now Remove Carbon, United Nations Says

Humanity is certain to exceed the warming limit set by the Paris Agreement, a legally binding treaty meant to cap the world’s carbon emissions, according to a new report from the United Nations Environment Programme (UNEP).

Now, to reduce severe threats to human health, food security, water supplies, and more, societies will need to reach net-negative greenhouse gas emissions by not only cutting those emissions, but expanding carbon dioxide removal projects, a pathway called “overshoot, peak and decline.”

Arctic Report Card Will Move Ahead Without NOAA

The Arctic Report Card, an annual, peer-reviewed evaluation of the state of our warming Arctic, will still be published this year despite a lack of financial or logistical support from NOAA. 

On 10 August, editors of the Arctic Report Card were informed that NOAA will no longer support its publication, meaning the agency will not provide the report with coordinating editors, coordinate its external peer review, or fund the report’s web presence, publicity, graphics, or summary video.

We’re Getting Better at Knowing When Climate Change Is to Blame, National Academies Report Says

Scientists have gotten much better at parsing how severe events are linked to climate change, a long-awaited report from the National Academies of Sciences, Engineering and Medicine has found.

The report was developed by 14 experts (including climatologists, meteorologists, and atmospheric scientists) and updates a 2016 report on the same subject. That report found that climate change was partly responsible for worsening heat waves, cold events, droughts, and heavy precipitation events, but that improvements to attribution science—a branch of climate science that aims to determine the extent to which individual extreme weather events are caused by climate change—were needed.
