Globally-averaged temperatures in 2016 were 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. Second, there will be more extreme heat events somewhere on Earth this year, because our influence on the climate has greatly increased the odds of record-breaking heatwaves occurring.Įven if we start acting on climate change with more urgency, we will experience more frequent and intense heatwaves in coming years. Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). This figure topped the previous record of 38.5☌ recorded in. To have an individual year as cool as those we experienced as recently as the 1990s is exceptionally unlikely due to our high greenhouse gas emissions. The current record high temperature in the UK is 38.7☌, which was reached at Cambridge University Botanic Garden on 25 July 2019. We can’t forecast the weather beyond about ten days, but we can make a couple of forecasts for 2022 with confidence.įirst, while 2022 may experience a slight cooling influence from the ongoing La Niña, it will still be among our warmest years. AAP Image/Stuart Walmsley What’s in store for 2022 and beyond The last six years were the six hottest on record in Mexico and climate change is to blame, according to the heads. Related: The Harshest Environments on Earth. The hottest year in the last when the average temperature was 22.6 C. Hundreds of people were evacuated in Forbes, NSW after a local river exceeded major flood levels in November, 2021. On July 10, 1913, the weather station measured a record high of 134 F (57 C), a temperature that has not been beat anywhere in the United States since. Last year, average temperatures in Japan reached the highest level since records began in 1898, and were almost a degree warmer than a typical year, according to the JMA. While La Niña is a natural phenomenon (it’s not the result of human activities), human-caused climate change remains a constant underlying influence that sets a long-term warming trend. This happens when wind strength increases at the equator, which pushes warmer water to the west and allows more cool water to rise off the coast of South America.Įssentially, the net transfer of energy from the surface to the deeper ocean brings the average global surface temperature down. So how does it work?īack so soon, La Niña? Here's why we're copping two soggy summers in a rowĭuring La Niña we see cool water from deep in the Pacific Ocean rise to the surface. In La Niña years, we see the global average temperature decrease by about 0.1-0.2℃. Summer 2019 brought some serious heat to the world breaking the record for the hottest summer on record for the Northern Hemisphere ever recorded. While it’s unusual for this climate phenomenon to occur two years in a row, it’s not unheard of. La Niña dampens the heat, but not enoughĢ021 started and ended with La Niña events. 2021 was one of the seven warmest years on record, WMO consolidated data shows.
