Scientists and researchers have reported record-breaking temperatures in the Northern Hemisphere, with major warm anomalies observed. Additionally, the ozone hole over Antarctica has been described as 'remarkably massive' and not recovering as expected due to factors such as fires and volcanic eruptions. The Arctic has also experienced consistent temperature anomalies well above the 1981-2010 average, particularly in previously sea-ice covered locations. Furthermore, a decline in Arctic sea ice thickness and volume over the past four decades has been noted. Data from various sources, including GISTEMPv4 and CopernicusECMWF ERA5 reanalysis, has been used to analyze these trends and anomalies.

Last month observed below average air temperatures around the Antarctic. Elsewhere, the largest warm anomalies were found in the Northern Hemisphere.

Temperature anomalies over the last month (left), 3 months (center), and 12 months (right) in the Arctic. They have consistently been well above the 1981-2010 average, especially over previously sea-ice covered locations. Data from https://t.co/e7aUafgc7S https://t.co/lmKznNwX95

Conflicting Reports On Antarctic Ozone Hole: Size Discrepancy Raises Questions About Recovery Efforts https://t.co/Nj7UPLWvb2
Antarctica's ozone hole may not be recovering as well as we thought. Major fires and volcanic eruptions have contributed to larger-than-usual "ozone holes" over Antarctica in recent years. https://t.co/eL8WIWKgE2 https://t.co/eYEQl4cVDX
This paper by Kessenich et al. shows that the #ozone concentrations over the #Antarctic have been steadily declining in mid-spring in the recent years due to changes in descending air at the core of the #OzoneHole. https://t.co/V7RjS0waov https://t.co/ARUaUzpV3O

Ozone Hole has been 'remarkably massive' over the past four years: Scientists warn gap over Antarctica is larger and deeper than ever - and say CFCs aren't the only things to blame https://t.co/zpOhh1eaZ6 https://t.co/HCct7rKJd9
