ALT Line graph time series of 2024's daily global sea ice extent in red shading compared to each year from 1979 to 2022 using shades of purple to white for each line. 2023 is annotated in yellow, which was a record low in the boreal summer months. There is substantial interannual and daily variability. Seasonal cycles are visible. A disclaimer is shown, which states: Trends/variability in Arctic and Antarctic sea ice are affected by very different atmospheric/oceanic processes and opposite seasonality!

ALT Green line graph time series of average sea surface temperature anomalies for each June from 1850 through 2024 for only the North Atlantic. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2024 is easily the warmest on record.

ALT Line graph time series of global mean surface temperature anomalies for every June from 1880 through 2024. A red 30-year lowess smoothing line is also shown. Anomalies are computed relative to a 1951-1980 baseline. The global mean surface temperature anomaly in June 2024 was +1.21°C. There is large interannual variability and a recent long-term warming trend.
