Better hope it changes, and fast, or we're absolutely fucked. That upwards incline of temperature is terrifying.
Also? Solar irradiance variance is about 0.07%. Temperature variance appears to be about 0.35%, or 5 times as strong (average temperature of the Earth is about 14.5 degrees Celsius, or 288 Kelvin). That's... not something you'd see under normal circumstances if irradiance was the only factor, and if it was a result of 'store and release received solar energy' with no meaningful changes in atmospheric composition you'd see a delay and a damping effect in temperature's response to solar irradiance. Something that you can actually spot in the 1880 to 1920 segment of the graph.
