The share of Americans who see solid evidence of global warming is at a 10-year high, and the acceptance of human impact has also trended upward, new polling data shows.

Expand chart
Data: Issues in Energy and Environmental Policy, July 2018; Chart: Harry Stevens/Axios

Why it matters: The latest from the ongoing series of University of Michigan and Muhlenberg College polls shows the public, as a whole, is getting slightly closer to endorsing consensus science on human-caused warming, but still remains far, far from full acceptance.

By the numbers: 73% of people polled in April and May see "solid evidence" of warming, a slight uptick from recent years.

  • That's about where it was a decade ago, but in twice-yearly polls between the fall of 2009 and spring of 2015, the total percentages bounced around from the low-50s to the mid-60s.

Check out the chart above: 60% — a record in their joint polling — see some level of human influence, including 34% who see direct causation. The consensus scientific view is that human activities, notably burning fossil fuels, have been the dominant driver of warming since the mid-20th century.

Yes, but: The political chasm is immense. Per the report:

"The divide between Democrats and Republicans on the existence of anthropogenic induced global warming is also at record levels with 78% of Democrats now holding the view that humans are at least partially responsible for warming on the planet compared to only 35% of Republicans."

Go deeper: The political divide over climate science.

Johnson & Johnson said in a press release Tuesday a global study showed that the protection offered by its coronavirus vaccine was strengthened by a booster shot.

Why it matters: While J&J has not formally applied for authorization to offer booster shots to the general public, it said it has shared the results of the study with the Food and Drug Administration and plans to share it with the World Health Organization and other health regulators.

U.K. prosecutors said they had enough evidence to charge Denis Sergeev, a member of the Russian military intelligence service, in the 2018 Salisbury nerve agent attack against a former Russian spy, according to AP.

Why it matters: Sergeev is the third person to face charges for the nerve agent attack against Sergei Skripal and his daughter, Yulia, both of whom survived.
