POV FOOTAGE SHOWS POLAR BEARS STRUGGLING TO FIND FOOD

Millions have seen the heart-wrenching video of a polar bear clinging to life, its white hair limply covering its thin, bony frame. Shot by Paul Nicklen and Cristin

a Mittermeier of the nonprofit group Sea Legacy, and published on National Geographic in early December, the video ignited a firestorm of debate about what scientists know, and don’t know, about the impacts of global warming on polar bears. Without examining the bear in the video—thought to have died—it’s impossible to know for sure what ailed that individual, but now scientists have published new findings that shed more light on the risk to the species overall.

Reef protection, despite official advice recommending against the projects, or repeatedly finding them to be failing.

The contracts include millions of dollars for tourism operators to cull out-of-control coral-eating crown of thorns starfish. Funds continue to be distributed, despite researchers employed to evaluate the program repeatedly finding it to have failed, and potentially having made the problem worse.

It also includes $2.2m spent on an unusual project involving giant fans installed on a small part of the reef to cool water down to prevent bleaching. Documents obtained by the G

Scientists have a new, narrower estimate of "climate sensitivity," a measure of how much the climate could warm in response to the release of greenhouse gases.

The new study, published in Nature, refines this estimate to 2.8°C, with a corresponding range of 2.2 to 3.4°C. If correct, the new estimates could reduce the uncertainty surrounding climate sensitivity by 60 percent.

The narrower range suggests that global temperature rise is "going to shoot over 1.5°C" above pre-industrial levels, the lead author told Carbon Brief, but "we might be able to avoid 2°C." Meeting either limit will l

A team of divers in eastern Mexico have discovered what’s believed to be the longest underwater cave in the world, just three miles west of the white sand beaches of Tulum.

The findings confirm that the vast, 164-mile-long Sistema Sac Actun, a waterlogged system of natural sinkholes, or cenotes, is actually connected to the nearby 52-mile-long Dos Ojos system, bringing the total length of the caves to a winding 216 miles. That’s more than the combined height of 24 Mount Everests stacked on top of one another. The warren of caves also stretches downward, to a depth of more than 332 feet, mak

The utility in question is Xcel Energy, Colorado’s biggest, which serves 3.3 million electricity customers in the upper Midwest, Colorado, and New Mexico.

In 2016, Xcel released its Colorado Energy Proposal, which was news in itself. The utility proposed to shut down two coal plants in the state and replace their output with roughly 700 MW of solar, 1 GW of wind, and 700 MW of natural gas by 2023. That would put Xcel’s Colorado energy mix at roughly 55 percent renewables.

We are destroying the world’s biodiversity. Yet debate has erupted over just what this means for the planet – and us.

Just over 250 million years ago, the planet suffered what may be described as its greatest holocaust: ninety-six percent of marine genera (plural of genus) and seventy percent of land vertebrate vanished for good. Even insects suffered a mass extinction – the only time before or since. Entire classes of animals – like trilobites – went out like a match in the wind.

In a study published this weekend in the journal Environmental International, a team of researchers from the University of Exeter found that regular surfers and bodyboarders are four times as likely as normal beach-goers to harbor bacteria with high likelihoods of antibiotic resistance. This is because surfers typically swallow ten times more seawater during a surf session than sea swimmers.

The pollution-beleaguered country plans to increase forest coverage to 23 percent of its total landmass by the end of the decade.

In addition to the abundance of trees, the government has enacted an “ecological red line” program, reports Stanway, a plan that will require provinces and regions to restrict “irrational development” and limit building near rivers, forests and national parks. Fifteen provinces have already created plans, with the other 16 provinces to follow suit this year.
