This chart shows the actual temperature, not the anomaly (that is, not the difference in temperature from the long-term average for that day.) It's falling because of the season. Even though it's spring moving into summer in the southern hemisphere, at first sight offsetting the reverse process in the NH, because a larger proportion of the NH is land, it cools faster than the SH heats up, since much more of the SH is water. So you get an annual cycle of actual temperatures for the world as a whole, as opposed to the situation with temperature anomalies. In other words, the declining temperatures shown in the chart are not secular, but seasonal. It's not the end of global heating, just a temporary respite.
The short-dash line shows the average temperature for these dates for 1979-2000; the medium-dash 1981-2010; and the long dash, 1991-2020. Each one is higher than the previous one. The orange line shows the temperatures for 2023, for these dates, and the red line for 2024.
The conclusions are obvious. As is the inaction by our politicians and CEOs.
