The increase in carbon dioxide concentration warms more than anticipated

I have previously followed with great interest the progress of climate change. In doing so, I have personally observed how ground-level measurement data has been retrospectively altered in such a way that there may not be reality-based justifications, such as changes in the location of thermometer or adjustments for temperature changes due to urbanization.

Therefore, my interest has shifted mainly to monitoring the surface area of the Arctic sea ice because I find its distortion quite challenging or downright impossible. To my satisfaction, I have also noted that there have been no significant changes to these statistics.

Today I read a recent study that measured the impact of atmospheric carbon dioxide concentration on the lower atmosphere's temperature. Increasing it (CO₂) has so far been thought to have a direct effect on the global average surface air temperature.

However, this is not the case, as Haozhe He et al. found that doubling the atmospheric CO₂ concentration increases the impact of CO₂-induced growth by about a quarter. In other words, the more anthropogenic CO₂ emissions accumulate in the atmosphere, the more serious the consequences.

In essence, He et al. presented a prediction - or hypothesis - that the lower atmosphere's temperature should rise more rapidly as the climate warms. Therefore, I plan to monitor how this is reflected in the fluctuations of the Arctic sea ice area - above all, whether it begins to melt again after statistically remaining the same size for over a decade despite the increase in CO₂ concentration.
