Fantastic resource for anyone interested in energy efficiency πŸ’‘πŸ§ͺπŸ”Œ

Interesting, yes. But somehow you'd think 2.2 meters in 2300 is least of our problems... given that the climate change may render several countries uninhabitable in this century.

Well it would be quite strange if he was against voluntary migration because that would mean that he would try to stop them from leaving!

So, you are basically telling that the virus can go to liver? Quite something.

Thought it over, and to me it seems that this is kind of an 'animal spirits' panic. The EU exports to US amount to 2.7% of EU's GDP. The firms shouldn't loose much of their substance value if the Transatlantic trade is eliminated. (Don't know the situation in Asia.)

Is there a rational reason for panic? Exports to US amount to some 3% of EU's GDP. If that trade is eliminated, the first order effect on Eurpean firms' values should be 3% #EconSky

Two obvious sectors which won't stop growing are health care and defence. In a zero-growth future, we're faced with a tough choice: Either we let these sectors to swallow up a larger and larger chunk of the economy or we accept that we can't deliver the modern standards.

Eyeballing S&P, the IT bubble burst took well over 1/3 of the market's value and the finance crisis, almost half! But can FED let that happen again!??!

β€˜An exciting moment’: England’s urban and rural trees mapped for first time β€˜Groundbreaking’ tool aims to help tree-planting efforts and identify areas to create nature-rich habitats

As someone always on the look out for spatial data layers, this looks pretty exciting!

Must be extreme fun for the teacher to mark those. I mean, it's very difficult to gauge the right amount of points out of 66.

Of course you Sir know all of this but I was referring to a general reader.

I'd say learn to know the general pattern first. Classical constellations may not be the best place to start, you might want to look for asterisms and individual bright stars first. Navigation star maps are quite good. Typical astronomical maps have quite a lot of detail.

One Bird Nest, 30 Years of Human Trash (Gift Article) A coot’s nest reveals that what humans throw away doesn’t really go away.

"It’s...a physical embodiment of how profoundly humans are reshaping the environment...and how long-lasting the effects can be..."Just one meal from one person β€” the packaging is still here,” Mr. Hiemstra said. β€œA bird has been breeding on it for 30 years.”"

Have had that feeling a million times. But what's good, is that when you to look at the paper in google scholar 10 years later, you often learn that you've got cited. Then, on the other hand, it's a bit sad that you never got to know these people.

Can you elaborate what's the usefulness over CRP + clinical exam? (I guess there's one, but want to here from an expert.)

Perhaps they're a bit more progressive than the Finns, in this respect. As in Japan, the majority of forests are privately owned and that creates a certain friction. People see it as an inter-generational investment.

That's a very good point. That kind of OLS analyses could convince economists, they use them a lot. I think the obvious argument from the MAGA cultists would be: 'Hey, but the timeseries have been trigged!'
