Can Frogs Survive Being Frozen?

Posted by in category: climatology

Warm weather brings thoughts of spring peepers and leaping bull frogs. But what happens to frogs in the winter? If they can’t dig down far enough into the soil to avoid the ice or aren’t lucky enough to live in warmer climates, some actually freeze.

Fortunately for them, they don’t freeze to death: Most survive to mate another spring.

There are five known species of freeze-tolerant frogs in North America, including the well-studied wood frog, as well as Cope’s gray tree frog, the eastern gray tree frog, spring peepers and the western chorus frog. In the fall, these frogs bury themselves under the leaves on the forest floor — but not deeply enough to escape the icy fingers of Jack Frost.

‘Exceptionally rare’ lightning storm stuns Puget Sound

Posted by in category: climatology

SEATTLE, Wash. — There were 2,275 bolts of lightning in Saturday’s lightning storm that shocked Puget Sound, according to the National Weather Service on Sunday.

“To have this much lightning in the lowlands is exceptionally rare,” said Reid Wolcott, Warning Coordination Meteorologist for the National Weather Service.

SpaceX says more Starlink orbits will speed service, reduce launch needs

Posted by in categories: climatology, satellites

WASHINGTON — SpaceX is asking federal regulators to allow it to spread out satellites in more rings around the Earth, saying the tweak to its orbital plans could bring coverage to the southern United States in time for next year’s hurricane season.

In a filing to the U.S. Federal Communications Commission, SpaceX said it wants to triple the number of orbital planes at 550 kilometers, the altitude where its lowest layer of Ku- and Ka-band Starlink satellites are to operate.

SpaceX launched its first 60 Starlink satellites May 23 on a Falcon 9 rocket. The company needs another six Starlink launches before it will have enough satellites to start partial service, but by splitting satellites into 72 rings instead of 24 as originally envisioned, Starlink will be more spread out, enabling greater launch efficiency, SpaceX said.

Hurricane Dorian Now a ‘Catastrophic Category 5’ Storm

Posted by in category: climatology

Hurricane Dorian is now a “catastrophic Category 5” storm and the strongest on modern record as it approaches the northwestern Bahamas in the Caribbean, according to a National Hurricane Center update today (Sept. 1).

As of 11 a.m. EDT (1300 GMT), Dorian has maximum wind speeds of 180 mph (285 km/h) as the storm churns about 20 miles (30 km) east of Great Abaco Island, the NHC wrote in the update. The storm is about 205 miles (330 km) east of West Palm Beach, Florida.

“Devastating hurricane conditions are expected in the Abacos Islands very soon and these conditions will spread across Grand Bahama Island later today,” NASA officials said today in a morning update.

Can We Capture Energy From a Hurricane?

Posted by in category: climatology

As destructive natural phenomena go, hurricanes are among the heavyweights. If not for the gale-force winds and resulting projectile debris, then for the massive flooding that results when one makes landfall and stalls out, a hurricane is a nasty piece of work. Just ask the residents of the coastal Carolinas and Georgia this week as they wring themselves out from Hurricane Matthew’s weekend deluge.

This Hurricane Proof House Made From 612,000 Recycled Plastic Bottles Can Withstand 326 MPH Winds

Posted by in categories: climatology, habitats

If you’re looking to build a new home on coastal waters where hurricanes are known to roam, you might want to skip the two-by-fours and cement and instead start drinking bottled soda. A Canadian company has recently completed construction of a home with exterior walls made from recycled plastic, and it’s claimed to be able to withstand winds gusting at over 300 miles per hour.

Built by JD Composites, the three bedroom home is situated near the Meteghan River in Nova Scotia. Aside from a distinct lack of trees, gardens, and neighbors, the house looks like any other dwelling with a clean modern design and a minimalist facade. Inside it’s fully furnished and finished with drywall covered lumber walls, but the exterior is what makes the house appealing as a new, and seemingly much improved, approach to construction.

How Cheap Must Batteries Get for Renewables to Compete With Fossil Fuels?

Posted by in categories: climatology, finance, sustainability

While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can’t provide the 24/7 power we’ve become used to. At present, that’s not big a problem because the grid still features plenty of fossil fuel plants that can provide constant baseload or ramp up to meet surges in demand.

But there’s broad agreement that we need to dramatically decarbonize our energy supplies if we’re going to avoid irreversible damage to the climate. That will mean getting rid of the bulk of on-demand, carbon-intensive power plants we currently rely on to manage our grid.

Alternatives include expanding transmission infrastructure to shuttle power from areas where the wind is blowing to areas where it isn’t, or managing demand using financial incentive to get people to use less energy during peak hours. But most promising is pairing renewable energy with energy storage to build up reserves for when the sun stops shining.
