A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.
Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.
It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.

. . . The increasing visibility of climate change, combined with bleak scientific reports and rising carbon dioxide emissions, is taking a toll on mental health, especially among young people, who are increasingly losing hope for their future. Experts call it “climate grief,” depression, anxiety and mourning over climate change.

In a little over a month, the so-called Green New Deal has won endorsements from more than three dozen sitting or incoming federal lawmakers as Rep.-elect Alexandria Ocasio-Cortez (D-N.Y.) makes a high-profile bid to shift debate over climate change toward policy on the scale of the crisis.
On Friday, the effort got a boost from 311 state and local officials.
Forty-four mayors, 63 county and state legislators and 116 city council members were among the officials from 40 states ― including some top oil and gas producers ― who signed an open letter issuing a sweeping, full-throated call for the phaseout of fossil fuels and adoption of Green New Deal-style climate policies.

. . . One Concern is launching a machine learning platform that provides cities with specialized maps to help emergency crews decide where to focus their efforts in a flood. The maps update in real-time based on data about where water is flowing to estimate where people need help the most. It’s the latest in a wave of AI-powered tools aimed at helping cities prepare for an era of severe, and increasingly frequent, disasters.

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.
The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.
Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.
Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Britain’s gone nine days with almost no wind generation, and forecasts show the calm conditions persisting for another two weeks.
The wind drought has pushed up day-ahead power prices to the highest level for the time of year for at least a decade. Apart from a surge expected around June 14, wind levels are forecast to stay low for the next fortnight, according to The Weather Company.

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.
Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .
. . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.
