Tu BiShvat, the Jewish new year of the trees, barely registers on most Jewish calendars, except as an occasion to plant trees or eat fruit and nuts.

But the one-day holiday, which begins Sunday (Jan. 16), has gotten a boost these past few years as environmentalists have reimagined it as the Jewish Earth Day. This year, Tu Bishvat started early with the Big Bold Jewish Climate Fest, a five-day online event (Jan. 10 -14) that has drawn hundreds of Jews to reexamine ways to make climate action a central priority of the Jewish community.

Their state budgets flush with cash, U.S. Democratic and Republican governors alike want to spend some of the windfall on projects aimed at slowing climate change and guarding against its consequences, from floods and wildfires to dirty air.

Democratic governors such as California's Gavin Newsom and Washington's Jay Inslee have been clear about their plans to boost spending on climate-related projects, including expanding access to electric vehicles and creating more storage for clean energies such as solar. Newsom deemed climate change one of five "existential threats" facing the nation's most populous state when he rolled out his proposed state budget this past week.

The tsunami threat around the Pacific from a huge undersea volcanic eruption began to recede Sunday, while the extent of damage to Tonga remained unclear.

An unprecedented, experimental attempt to feed manatees facing starvation in Florida has started slowly but wildlife officials expressed optimism that it will work as cold weather drives the marine mammals toward warmer waters.

A feeding station established along the state's east coast has yet to entice wild manatees with romaine lettuce even though the animals will eat it in captivity, officials said on a news conference held remotely.

The ashes of Winter the dolphin were returned to the sea, about two months after the beloved marine mammal of movie fame died at a Florida aquarium.

On a gusty mountain crest, the Jama brothers weave between wind turbines that stretch as far as the eye can see, on what used to be their animals' winter pasture. Climate emergency or not -- for these reindeer herders, the turbines have to go.

"Before, the area was perfect for our reindeer. The place was pristine, unspoiled by human activity. Now, everything has been ruined for years to come," laments Leif Arne, the younger of the brothers, at the wheel of his 4x4.
