Yes there is much we need to do and can do. As we ramp up on pledges quickly we reduce future impacts of droughts, wild fires, hurricanes and other climate related local disasters. We will reduce the effects of sea level rise, and avert warming levels likely to lead to millions of climate migrants (chapter 3, section 3.4. 12 and Figure 3.4 page 246). These actions are also good for our economy and better for biodiversity. By staying within 1.5°C, we can save coral reefs from near extinction, and reduce the amount of adaptation needed for many ecosystems.

This is an internet joke event. Lots of people saying they will go just for the fun of it. Out of those 2 million or more, it would be a surprise if 50 actually turn up. This is what they plan to do, a Naruto run

UPDATE - THE EVENT GOT CANCELLED

The music festival event got canceled, and the original organizers say to stay away saying:

This may help with this and other fake asteroid news. It's a no hazard asteroid.

There is no NASA warning at all. They have already removed 88 "no hazard" asteroids from their table so far this year.

It’s a 11 million to one against, and it's like rolling 9 or 10 dice and getting a six every time. An object this size hits only every 94,000 years.

They search for them so that they can warn us if they are going to hit. With a warning then we can either deflect it or evacuate the impact zone. There is no warning for this one.

This is being reported in a way that scares some people But this is not new climate research, and changes nothing about the 2018 IPCC report. It is just a public education paper, helping people to understand the consequences of climate change, and evaluate environmental policies. It could have been written any time in the last decade and would have been essentially the same with minor tweaks.

This paper in Nature shows that if the world including China and India gradually ramp up their commitments to become 1.5°C compatible, then the new coal fired power plants they built recently or are building right now will need to be used at low capacity or for a shorter than usual lifetime than the industrial average of 53% capacity for 40 years.
