THE WARMEST YEAR IN THIS DECADE
2019 is going to be a warmest year of this decade. because of El Nino and Global pollution.
Basically El Nino comes 3 to 5 years gapping. In the 2019 el nino is coming.
The past three years, from 2015 to 2017, were the warmest ever recorded. And although the current year started off with a moderate La Niña phenomenon—which generally has a cooling effect on global climate—it is going to end up being the fourth warmest year, clearly showing a warming trend.
In fact, the 20 warmest years on record have occurred in the last 22 years. This trend also sits in perfectly with the emission rates of greenhouse gases (GHGs), which were at a record high in 2018 according to the World Meteorological Organisation (WMO).
The combination of human-caused warming and a natural upswing in temperatures increases the odds that any new El Niño year will be the warmest ever,” climate scientist Michael Mann from Pennsylvania State University
One of the impacts of warmer surface temperatures and more ocean heat will be greater occurrence of extreme weather events such as tropical cyclones, heat waves, floods and droughts. In 2018, there were 70 tropical cyclones all over the world, while the long term average is 53. The world lost more than 5 lakh people to such events in the last 20 years along with an economic loss of US$ 3.47 trillion, according to the latest Global Climate Risk Index 2019 report.
By all indications, 2019 will also be a year of extreme weather which will add to these losses
