The northern hemisphere (including Greece), which accounts for about 90% of the world’s population, has experienced the hottest summer in meteorological weather since 1880, “leveling” at record temperatures in summer 2016, according to the National Oceanic Service. and Atmosphere (NOAA) of the United States.
The summer of 2019 (June-August) was the second warmest in the world, and this year August has been the second warmest in the modern meteorological history of the last 140 years. The five hottest summers in the northern hemisphere have all been in place over the past five years, and all five of the hottest Augusts have occurred after 2014, according to NOAA.
The Arctic’s ice-covered area was 30% below its historic average in August and the second smallest after 2012, while the Antarctic sea ice in August was the fifth smallest.
Temperatures in summer 2019 soar
It is noteworthy that this summer the temperatures got “uphill”, something that was particularly noticeable in Europe in July ( Paris set an all-time temperature record ), although – despite the also hot 2016 – there was no strong El Niño, which traditionally boosts global temperatures.
Scientists say that because of the rising levels of anthropogenic “greenhouse gases”, it is now easier to break new meteorological records even without El Nino’s help.
2019 is the third hottest year after 2016
Using slightly different methods, the US space agency (NASA) also found that the northern hemisphere in summer 2019 was the hottest in meteorological time, but marginally hotter than in 2016. On an annual basis, 2019 is by far the third warmer year after 2016 and 2017 and NOAA estimates it will eventually be second to fourth warmest (certainly in the top five).
