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.

Short summary - the Arctic is always on fire in summer, and it’s a natural part of the ecosystem, to the extent that moose, bears, bison, voles, foxes, owls, birds of prey, …, they are all dependent on the fires directly or indirectly. It would be a very different ecosystem without them. Part of the Arctic burns every year but other areas recently burned grow new growth such as birches, berries, herbs, willow, grassland, others then are turning into mature forests of spruce, which burn when they become very dry, others are peat banks that again burn when they are very dry and it cycles round and round.

Articles that warn about the effects on global warming are a bit premature. You need to look at all the effects over multi-year periods.

Ethiopia has just planted 353 million trees in 12 hours. It is part of the national “green legacy” initiative to encourage all its citizens to plant 40 seedlings each for a total of 4 billion trees over this summer.

Dr Getahun Mekuria, their minister of technology and innovation tweeted estimates through the day:

China is currently targeting a 20% non fossil share by 2030, and there were reports that it is expected to target 35% of electricity from renewables by 2030 according to drafts for its next plan, the “Renewable Portfolio Standard”.

This is a new study that makes the dramatic claim that as the ice melts in summer in the Arctic, then because ice reflects away more sunlight than water, this will have a dramatic warming effect on the whole planet, equivalent to 25 years of anthropogenic emissions. It's been scaring many people but there is nothing here to worry about. Short summary: The study did not take account of the way the melting ice causes cloud to increase (because of all the extra water vapour it puts into the atmosphere). They assumed constant cover. But the paper they cite for that only found constant cloud cover as the ice melts in mid summer. Minimum sea ice extent is in September.
