The above image, created with Climate Reanalyzer content, shows that June 2024 was substantially hotter than June 2023, which is significant since we're not in an El Niño anymore. Moreover, monthly temperatures are also rising.
According to Copernicus, the global-average temperature for the past 12 months (July 2023 – June 2024) has been more than 1.5°C above the 1850-1900 average. Carlo Buontempo, Director of the Copernicus Climate Change Service (C3S), adds: "June marks the 13th consecutive month of record-breaking global temperatures, and the 12th in a row above 1.5°C with respect to pre-industrial. This is more than a statistical oddity and it highlights a large and continuing shift in our climate." Note that, as discussed in earlier posts, anomalies from a genuinely pre-industrial base could be much higher. 

Arctic sea ice
The danger is that feedbacks and further developments will accelerate the temperature rise even more. Critical in this respect is the condition of Arctic sea ice. The image below, adapted from the Danish Metereological Institute, indicates that Arctic sea ice volume is at a record low for the time of year, as it has been for most of the year. At the same time, sea ice extent is still relatively large; Arctic sea ice extent was 3% below average in June 2024, close to the values observed most years since 2010, according to Copernicus. The implication is that sea ice must be very thin.

The amount of energy absorbed by melting ice is as much as it takes to heat an equivalent mass of water from zero to 80°C. Loss of the latent heat buffer threatens to strongly heat up the Arctic Ocean, and this increases the danger that further heat will reach methane hydrates at the seafloor of the Arctic Ocean, causing them to get destabilized resulting in eruption of methane from these hydrates and from free gas underneath that was previously sealed by the hydrates. 
DJ, The less ice remains the warmer it will get...stronger storms may transport even more warmth/rain to Polar regions=more melt...

Climate collapse = Pandemics !
