No, HVDC offers closer to 50% reduction in line loss versus AC.

UHVDC loses even less, and is now the standard for long-haul lines in China, the world leader in this. And few of these lines are buried.

A pity that we can no longer burn them.

Tell that to my gas company. They're talking up hydrogen nonstop -- while fighting rooftop solar, which says something about motives.

Biofuels can eliminate only half of aviation climate harms, so they are unacceptable as solutions. We must simply fly less or not at all until electric aviation arrives.

That depends entirely on where you live and which heat pump you choose. The latest high-HSPF models rarely resort to backup even in USDA zone 4. Still, I think we'll see many owners of existing homes there replacing older central AC units with heat pumps while keeping gas for security, much as many Canadians do. This will change over time as cold weather heat pumps keep improving.

"Madman who blames immigrants for his failures makes futile gesture before he offs himself."

So sad in a dozen different ways.

We are already in an extinction event, with 70% of wildlife along with many plant and insect species already gone.

However, we are far from committed to making ourselves extinct. There is still time to save a habitable planet for our kids, but only if we get a move on.

No. Current pledges and forecasts have us on a 2-3C by 2100 trajectory.

However, the range of possibilities above 2C is very wide, and the ensemble models ignore a number of potential feedbacks that could change outcomes.

China is in an economic downturn, and it has turned the country back towards coal power to some degree.

This plus the fact that the eye is surrounded by a giant thermal, so birds can dodge in and out of it for hours to stay aloft.

I've been told that among the oddities one sometimes sees in a hurricane eye are seabirds cruising around.

Yes, but what evidence is there that this will lead to mass famine in five years?

The issue this article raises is adaptability to aridity, which comes from plants having to "breathe" less.

And those will continue. However, there is no evidence that "large scale famine" is in the cards within 5 years. Saying there is merely discredits science.

The US NW has a dozen distinctly different climate zones, so which one? And how much water will you provide?

True, but wells do often stink.

Methane lasts for 9 years before becoming CO2, so why isn't its effect measured on a 9-year span rather than 20 or 100 years?

Hint: the world's most powerful industry doesn't want anyone saying methane is actually 140x worse than CO2.

5 years? No. 30-60 years is more likely. This is far faster than former IPCC forecasts.

Methane is far more than 25 times as potent as CO2 as a greenhouse gas. It's all relative to the time that methane exists before oxidizing to CO2. The 25x figure is measured over a century but methane only lasts for about 9 years, during which its greenhouse warming effect is around 140x CO2.

There is much industry pressure to stretch the time window by which methane's greenhouse warming potential is measured, because the longer the period the less harmful methane looks.

Go for the gross. Secretly drop some milk duds on the trail, then taste them to "identify the deer species". Or lick a worm or a slug, then dare her to do the same. Kids love it.

Then, at night, be sure to watch meteors, ask her to count the stars in The Pleiades, and look at the Andromeda galaxy with binoculars.

You were forgiven, believe me.

Shorelines. Water views.

(Many editors struggle with headlines.)

Second word: snakes. Third: sharks.

Still, I love swimming in Florida's crystal clear rivers.

Nothing in the universe is permanent, but it appears these droughts are unlikely to end for centuries. If anything, they are likely to continue growing worse.

Another article on this: https://www.newscientist.com/article/2340790-megadrought-could-become-the-new-normal-in-the-south-western-us/

It's right there in the abstract:

>Anthropogenic climate change has intensified ongoing megadroughts in
south-western North America and across Chile and Argentina. Future
megadroughts will be substantially warmer than past events, with this
warming driving projected increases in megadrought risk and severity
across many regions, including western North America, Central America,
Europe and the Mediterranean, extratropical South America, and
Australia.
