1Government science groups say that 2022 did not quite set a record for heat.
2But it was in the top five or six warmest years on record.
3The exact placement depends on who was doing the measuring.
4The U.S. National Oceanic and Atmospheric Administration (NOAA) measured 2022's worldwide average temperature as 14.76 degrees Celsius.
5That ranks as the sixth-hottest year on record.
6Four other scientific agencies or science groups around the world put the year as either fifth or sixth hottest.
7NOAA and NASA records go back to 1880.
8Bill Nelson is the NASA Administrator.
9He said the worldwide temperature is alarming.
10"What we're seeing is our warming climate, it's warning all of us... Extreme weather patterns threaten our well-being across this planet."
11Berkeley Earth is a nonprofit group of independent scientists.
12It said 2022 was the fifth-warmest year on record around the world.
13It noted that for 28 countries it was the hottest year on record.
14Since 2015, each year has been more than 1 degree Celsius warmer than pre-industrial times, NOAA and NASA said.
15Last year was 1.1 degrees Celsius warmer than the middle of the 19th century, NASA said.
16The possibility of Earth warming beyond the 1.5 degree Celsius limit that world leaders set in 2015 is increasing with every year, said the World Meteorological Organization.
17Russ Vose from NOAA said there is a 50 percent chance of hitting 1.5 degrees Celsius temporarily in the 2020s.
18La Nina, a natural process that changes weather worldwide, is in its third straight year.
19It is an event that reduces temperatures around the world.
20Gavin Schmidt is director of the NASA Goddard Institute of Space Studies.
21Schmidt found that last year La Nina cooled the overall temperature by about .06 degrees Celsius and that last year was the hottest La Nina year on record.
22Kathie Dello is the North Carolina state climatologist.
23She said that historically, La Nina would reduce worldwide temperatures.
24"Now, heat-trapping gases are keeping the temperature cranked up and handing us another top-10 warmest year on record."
25La Nina is likely weakening.
26But there is a possible El Nino on the way, which warms overall temperatures.
27Schmidt said this year will likely be warmer than 2022.
28And next year, he said, an El Nino "would suggest that 2024 would be the record warmest year by quite a large amount."
29Scientists say about 90 percent of the heat trapped by greenhouse gases goes into the upper 2,000 meters of the ocean.
30Data released Wednesday show that 2022 was another record year for ocean heat.
31John Abraham of the University of St. Thomas wrote a study on ocean temperatures.
32He said, "There's a real good connection between the patterns of ocean warming, the stratification, and then the weather that we experience in our daily lives on land," including stronger storms and rising seas.
33In the United States, global warming first received attention in 1988.
34That year would go on to be the record warmest at the time.
35Now, 1988 is the 28th hottest year on record.
36The last year that the Earth was cooler than the 20th century average was 1976, NOAA says.
