Why is hot season 2019 unusually hot?

Since the beginning of the year, Berkeley Earth Research Organization (USA) has predicted the possibility of 50% in 2019 will be the second hot year in history since 1850. Why is that?

In the middle of 2/2019, Thailand Meteorological Agency warned people about the next months of summer this year it will be very hot and dry, some places up to 44 degrees Celsius, last at least until those the first rains appear in May.

In fact, since the beginning of the year, the world's leading climate scientists have predicted that the Earth will experience an unusual heat wave, the probability of 2019 breaking last year's record to become the second hot year in history is 50% (since 1850).

And that happened in the past March.

According to the National Oceanic and Atmospheric Administration (NOAA), abnormal temperatures are recorded in many areas in Australia, northern peninsula of Alaska, northwest Canada, southern Brazil, Barents Sea, Tasman Sea and East China, and more areas scattered in the southern seas.

Meanwhile, a wave of hot air also swept across Europe during Easter. In Sweden, the forest caught fire because it was too dry, and in England and Russia . the people suddenly enjoyed the summer atmosphere (25-26 degrees Celsius) while this time was only . spring (different 10 degree deviation from normal).

Meteorologists explain the strange weather in the Asia-Pacific region this summer partly due to the effects of the El Nino phenomenon , which makes the western Pacific region hotter and drier.

Climate change also partly affects the weather this summer . Berkeley Earth - a research organization based in California (USA), accurately predicted the current heat wave since the beginning of the year by observing global temperatures.

In February, the US Aerospace Agency (NASA) and NOAA officially announced 2018 as the fourth warm year in history since 1880, only after 2015, 2016 and 2017. So, 5 years back This is the warmest period in the history of modern meteorology.

NASA scientist Gavin Schmidt stressed that the current climate is primarily caused by human emissions of CO2 and other greenhouse gases.

"The long-term impact of climate change can be felt - flooding in coastal areas, heat waves, rainfall and a highly variable ecosystem" - Mr. Schmidt warned.
