Can verify this. South of Portugal here. Just got home and there was 43°C outside an hour ago when I looked at a thermometer. I feel like I cannot think or process information in days like these. Awful to exist like this.

CO2 is at 425ppm. We're going to have a shit time.
That was yesterday. It's about 428 now. The line goes straight up, as capitalism demands.
427/8 was the February maximum. Today its 425.

Ah, of course, plant growth season makes the line squiggle.
I'll also note that land in general has warmed much more than sea surface temperatures. Unless you're living on a not-too-big island in a temperate location (eg: where The Guardian writers live) you're encountering this.
Land will heat faster than water, but will also lose that heat faster than water. That part makes the warming ocean a real big issue, as those warmer oceans will allow more destructive weather and eventually reshape climates. As well as the melting of polar ice raising sea level, humans better buckle up as we seem to have chosen the rough route to self extinction.
Can confirm.
