2024 was the hottest year in NASA’s record, which starts in 1880. Global temperatures were around 1.28 degrees Celsius (2.30 degrees Fahrenheit) higher in 2024 than the 1951-1980 average, the baseline period used in GISTEMP.

They found decreasing groundwater reservoirs, shifts in the timing of seasons, and more frequent extreme events by analyzing @NASA satellite data from 2003-2020.

Blue puddles of water were visible on the East Antarctic ice shelf after periods of record melting that took place at the end of 2024. These melt ponds are areas where the snow has melted and pooled in low spots on the shelf. Details:

NISAR will observe our planet like no mission before, helping us understand Earth’s changing land and ice surfaces.

@UnseenNight @NASA @NOAA According to NASA's GISTEMP analysis, 2024 (1.28°C; 1.23-1.33°C) was ~0.11°C warmer than 2023 (1.17°C; 1.12-1.22°C) a difference greater than the combined years' uncertainties, making 2024 an unambiguous new record.

@RandomSAguy @NASA @NOAA NASA's record starts in 1880, not because that’s when it was last this hot, but because 1880 is when we feel it becomes possible to calculate consistent, reliable measurements of surface temperatures globally.

@MaryleeUSA @NASA @NOAA Our record goes back to 1880, however that doesn't mean that temperatures prior to 1880 were hotter than present. Our current warming is unprecedented in many thousands of years, something we know from looking at data from tree rings, corals, ice cores, and ocean sediments.

RT @NASA: 2024 was the warmest year on record. Our experts work with @NOAA scientists to track Earth’s average temperature, relying on mill…

@Rob4B1 @NASA @NOAA Although climate comprises weather patterns over a long time, short-term or regional deviations in weather do not disprove climate change. Just because one month or one location is cooler than usual does not mean the planet’s temperature isn’t warming overall.

@AddysShout @NASA @NOAA NASA’s surface temperature analysis takes in millions of observations from thousands of weather stations including many rural stations, ships and ocean buoys, and Antarctic research stations.

We choose to start our record in 1880, which is when we feel it becomes possible to calculate consistent, reliable measurements of surface temperatures globally. Instrumental data from earlier decades are more sparse and uncertain, and so uncertainties increase markedly before 1880. But, using data from other sources like tree rings, ice cores, and ocean sediment, we can reconstruct a much longer record of Earth's climate, which confirms that the current warming is unprecedented for many thousands of years.

Our record goes back to 1880, however that doesn't mean that temperatures prior to 1880 were hotter than present. Our current warming is unprecedented in many thousands of years, something we know from looking at data from proxies like tree rings, corals, ice cores, and ocean sediments.

@daytoday111 @MacJMacLeod @NASA @NOAA This information comes from NASA climate scientists with decades of experience and data at their fingertips, in agreement with thousands of climate scientists around the world.

Increasing greenhouse gases and resulting warming will not cause glaciation. There is active scientific research about the potential impact of warming on the Atlantic Meridional Overturning Circulation (AMOC), a ‘conveyor belt’ of heat in the ocean. If the AMOC is significantly slowed or stalled out by melting ice, it might result in less warming in the North Atlantic region than would otherwise occur. However, the region would still warm overall and there would be little impact on the amount of warming averaged worldwide.

While the climate can and does change naturally, NASA researchers and scientists around the world have concluded that the long-term observed warming is due to human activity by identifying “fingerprints” in climate observations specific to warming caused by our increased greenhouse gas emissions, as well as studying and ruling out natural causes of climate change, such as changes in solar energy, volcanic activity, or ocean circulation. Only the patterns from changes in greenhouse gases match the long-term changes we see.
