Mudança climática pode duplicar furacões em 2020

By Ninian Carter

August 18, 2020 - Com previsões de uma época de furacões no Atlântico acima do normal
em 2020, o Kyle ultrapassou o Katrina como 11ª tempestade mais precoce.

The latest Atlantic storm is the earliest date, since record keeping began in 1851, for a storm with a “K” name – storms are named alphabetically throughout the season, K being the 11th letter of the English alphabet.

So far in 2020, five storms have hit the United States, eclipsing the pace in 2005 when a record 27 named storms formed, including the devastating Hurricane Katrina that killed 1,200 people and caused $125 billion of damage.

Although storm season technical runs from June 1 to November 30 each year, observers know that the trouble really begins from around August 20 to September 30 – when the Main Development Region (the stretch of ocean from the Caribbean to Cabo Verde off the African coast) becomes supercharged.

As a result of climate change, global temperatures have risen by around 1°C. The warmer Atlantic Ocean combined with a decreased wind shear, is leadsing meteorologists to believe more storms are coming in 2020.

Earlier this month, the National Oceanic and Atmospheric Administration (NOAA) increased its May prediction of 13 to 19 storms, to 19 to 25. Government forecasters have never called for 25 storms in a single season before – more than double the annual average of 12.
