“We can measure that distance of each individual photon traveling inside the snow,” says Hu, a researcher at NASA’s Langley Research Center.Just as an ant wanders around its underground colony, a photon shot from a space laser takes a random route through the snow.

The Tesla Model 3 (which Hu himself drives) uses nickel-free LFP, which is typically cheaper and safer, with a long battery life: “Hundreds of thousands of miles,” he says.

To further confuse matters, Europeans have had a tendency to label just about any game bird they encountered a “partridge.” several North and South American species are often called partridges, even though they are not.The long-tailed tree quail looks quite partridge-like.

Today, only one glacier remains in Venezuela: on the second highest peak, Pico Humboldt.“It’s an era that is [almost] completely finished now,” says Melfo, a particle physicist at the University of the Andes, who has recently been working on projects involving biology and ecology, including research on this last glacier.

To find out, Sheldon and his colleagues hauled buckets of seawater up to the Hudson’s laboratory and used a plankton-counting machine to total up the size and number of creatures they found.

Squirrels are also capable of changing course mid-jump and making split-second decisions about how far to leap depending on the strength of a branch.At least, that’s what former University of California Berkeley researcher Nathaniel Hunt and a team found after years of studying fox squirrels near campus.

“So you get kind of this baking-in factor over the course of multiple days of heat,” says Portland State University climate adaptation scientist Vivek Shandas, who has studied the heat island effect in Portland, New Orleans, and dozens of other cities.

Those repeated disasters mean that utilities have a recovery playbook for storms like Ida. But knowing what order to run those plays in depends entirely on the unique conditions left behind by each hurricane—which regions remain inaccessible for days due to flooding, and which specific components of the system need extensive repairs.

That’s a significant update from a previous IPCC report that predicted that the planet would hit the 1.5 milestone at around the year 2040, says Zeke Hausfather, a climate scientist and the director of climate and energy at the Breakthrough Institute, who wasn’t involved in the report.
