Positive Side Of Climate Change Facts - After Two Years Of Climate Change Action, Heading For 3°C With 1.5°C Well Within Reach

Almost nobody seems to report the positive side of our recent climate change action. It’s...

First this site has never been used for missile launching. It has only been used for satellites as part of North Korea’s ambitious civilian space program. They want to become one of the few countries able to launch satellites to geostationary orbit.

Although it could be used for a missile test, this seems unlikely. One suggestion is that it is to have more things to offer to demolish as part of future negotiations. Other suggestions include signaling impatience with the pace of negotiations, and a chess move to ratchet up pressure on Washington. It is not an attempt to do anything in secret as they know the world watches everything they do here. Whatever their reasons, they are doing it intentionally for show.

Short summary. The journalist stories often don't even mention that studies are not agreed on whether it is carbon positive or even perhaps carbon negative. The amount in the worst case is around an extra quarter of a degree rise by 2100, a slow burner through to the next three or four centuries. That is for “business as usual”.

For 3°C which we are close to already and easily achievable, then it is possible that it remains carbon negative and removes the equivalent of CO2 a fifth of a degree by 2299, and at most it is a fifth of a degree increase by 2299.

It is reasonably good news. Kim wanted the US to drop all sanctions in response for dismantling the publicly disclosed plant to make nuclear weapons materials. They weren't ready to do that. The US were willing to drop all sanctions in response to him completely denuclearizing but he wasn't ready to do that. He has a vision but not the same as the US vision but closer than it was a year ago.

Trump talked about them knowing the country very well (including nuclear facilities that NK has not disclosed). And that he wasn't willing to do enough.

Not a big disagreement. More that they were on the point of a big agreement but it fell through. And as Trump said he is not afraid to walk away from a deal.

Short summary - NASA did not warn about this - it’s only at warning level 0 and has to be 5 or above to be of public concern. The best fit projected orbit takes it to somewhere out beyond Mars's orbit in December, and what's more, at the opposite side of the sun from Earth on that date. But based on only three and a third days of orbit. If it was going to hit then our telescopes should have spotted it by now. In particular, the new ATLAS early warning system has a warning time of a year for one kilometer or larger asteroids with 100% confidence. So I think we are pretty safe from this one.

It is at warning level

This UN Report is not saying we are going to be unable to feed everyone. But we need to be careful to maintain the biodiversity of the wild relatives of our crops and also of our ecosystems to be most resilient. We don’t risk mass famine, they say that specifically in the interview with the BBC but we need the biodiversity to deal with future issues such as for instance pests and diseases of our crops. On this the situation is rather encouraging, especially if you read the report itself.

Please don’t be scared by this, it is just the journalists hyping things up again. It does not mean what it seems to mean from the headlines. Insects can’t vanish and we will continue to be able to grow our crops and do agriculture. The study itself involves a lot of extrapolation on inadequate data, not their fault, it is just that there hasn’t been that much research done on insect populations for them to draw on.
