I’m jumping between two different topics rather than doing separate posts.
Firstly, global temperatures. As per usual, I’m looking at the satellite data set from UAH, not because it’s the best but because it avoids a couple of bad faith arguments about the data:
La Niña slowing things down right now, making for a relatively wet summer in Australia. Not wet enough to avoid bushfires though https://www.theguardian.com/australia-news/2021/feb/02/fierce-bushfire-in-perth-hills-is-a-threat-to-lives-and-homes-warns-wa-premier
Jumping to the pandemic, a question I was asked is when we will see vaccinations make an impact on Covid cases? I haven’t found an article on that but it is a good question. The short answer is “not yet” looking at the graphs and it might not ever.
Here is the cumulative case numbers relative to population size for the top three countries for vaccination roll out. It’s way too early to see any impact.
Vaccines may not impact these numbers at all (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)32318-7/fulltext ) but should impact mortality and other impacts (i.e. covid might well stick around but do less damage).
