DID THE CLIMATE EXPERIENCE A REGIME CHANGE IN 2023?
The astonishing rise in temperatures makes one wonder whether a Regime Change did take place in 2023.
As the first image shows, the February 2024 temperature was 1.76°C above 1885-1915, potentially 2.75°C above pre-industrial (bright yellow inset right). The red line (6 months Lowess smoothing) highlights the Regime Change that may have occurred in 2023.
…The temperature rise since pre-industrial could be as large as 2.75°C. Such a rise corresponds with almost ⅕ more water vapor in the atmosphere.
The second image shows world daily sea surface temperatures (60°S-60°N) through April 8, 2024. For more than a year, sea surface temperatures have been much higher than in any previous year on record, as if temperatures suddenly shifted into another gear and the climate experienced a Regime Change in 2023.
There is no single feedback behind such a Regime Change, instead there are numerous non-linear feedbacks that may have all started to interact and kick in with greater ferocity, amplifying and accelerating the rise.
Such feedbacks may include more water vapor (as mentioned above), stronger storms, increased stratification of oceans, loss of sea ice, loss of reflectivity of clouds and increased freshwater accumulating at the surface of oceans, due to stronger ice melting, due to heavier runoff from land and rivers and due to changes in wind patterns and ocean currents and circulation.
