This is a plan for a wind turbine hub in the North Sea on Dogger Bank, that could up to 180GW by 2045 in time to help Europe achieve net zero emissions. The “Dogger Bank”, is the sunken Doggerland, a region of the North Sea that used to be above the sea in the last ice age. It is far from land, so winds would be much more steady.

The shallowest parts are only 15 meters below sea level making it an ideal place to build artificial islands (a bit like the Chinese artificial islands in the South China sea) and build sea turbines like this. The turbines could be towed into place as is already done for offshore wind. This video briefly describes it:

These "Living Planet Index" population figures are potentially confusing if you don't know how to read them and they have lead to many mistaken media stories.It does not mean that there are 88% less total numbers of large animals in our rivers and streams. We do not risk a world without salmon, hippos, beavers or crocodiles. Many outlets also ran it as a story about a greatly increased extinction risk for these animals. They did not even assess extinction risks and nothing in this report overrides the work of the IUCN red list.

You can always find bad news if you look for it.With the internet and social media we learn about every bad thing that happens throughout the entire world almost instantly. However the good news doesn't get shared so much. For instance how many of you are aware of the vast amount of work being done worldwide to restore eroded damaged landscapes (see below). How many people share them? Hardly anyone.

While working on my posts for the Debunking Doomsday blog, I come across a lot of good news that never gets into the mainstream media. Sharing some of them may help those of you who get depressed and scared by the journalist exaggerations and pessimism.

With the greenland ice melt in the news, what can we do to adapt to a rising sea level, and how much will it actually be? First, the melting this summer was nothing unexpected. Last year Greenland had so much snow in 2017–8 that it actually gained ice rather than lost ice. So, now we have a warmer summer and it loses more than usual - not a big deal. This of course is the northern hemisphere summer which is why this news is about Greenland rather than Western Antarctica.

Mark Serreze, Director of the National Snow and Ice Data Center, interviewed by Discovery blog put it like this:

Short summary. The 0.5 mm sea level rise due to ice melting in July is dramatic but you need to compare it with the rest of the year. July is usually the top month for ice loss. In the winter the Greenland ice sheet gains ice through snowfall, so you need to look at the balance between losses and gains.

Also you need to compare it with previous years. It’s actually not quite enough of a melt so far to beat the 2012 record. The Arctic sea ice minimum this year is also not expected to be as low as the 2012 minimum. .

This is nothing to be scared of. Just an unsurprising increased melt, after a previous year when there was so much snow that Greenland actually gained ice due to heavy winter snowfall in 2017–8

This is surely going to be one of the 93% of bills that never make it to law. First there is his op. ed. and surely this is not serious:

First his “maybe we’d be better off if Facebook disappeared.” is part of an argument. He is saying we need to be tough on social media and not let ourselves be shoved around by them.

Confront the industry, we’re told, and you might accidentally kill it — and with it, all the innovation it has (supposedly) brought to our society.

Maybe. But maybe social media’s innovations do our country more harm than good. Maybe social media is best understood as a parasite on productive investment, on meaningful relationships, on a healthy society.
