Temperatures rose from January to March but dropped right back in April, from March's 0.566°C to 0.34°C. That makes it the coldest month since the 2016 El Nino, behind December's 0.391°C. But even so, it was warmer than the annual averages of both 2014 and 2015, each a record in its time.
The main cool places were Canada, N Europe and Antarctica. China, E Siberia and the Arctic Ocean were warms was even most of the US.
Update - slightly OT, but you may notice that the TempLS report for March has a strange number (0.653°C) for that month. The main table above it has the correct number. The reason seems to be that in GHCN in the last few days, a whole lot of March data has gone missing, as you can see in the station map of the report. I hope they fix it soon. Fortunately, the lack of data prevents it updating the main table.
Update 2 - I wrote to GHCN but no response so far. Meanwhile, the pattern has changed - no longer whole countries missing, but more stations overall, so that now TempLS won't report at all.
Update 3. I got a response from GHCN saying that it was an ingest problem, now fixed. And it does seem OK now.
Quite a dip. Looks like May could be a lot warmer than April, so this episode of Global Cooling may disappoint the political types.ReplyDelete
Do you know why the daily anomaly number for May 1 is showing such a glitchy and impossible number? Hope the bug can be fixed soon :) Thank you for all your information on this site! :) Best regards!ReplyDelete
It's in the data - Walter has an explanation here. I'll fix the code so it doesn't wreck everything.Delete
There was an unusually large drop in TSI during April. Now that TSI has recovered the daily re-analysis temps are rebounding.ReplyDelete
According to daily LASP TSI data, which only goes up to 4/28/17, April's TSI at 1 AU is actually +0.03 W/m2 more than March's.Delete
