Climate-induced disasters will continue

Climate-induced disasters will continue

The increasing trend and greater intensity of climate-related disasters observed in 2015 will continue this year, and there have already been `` new records of monthly maximum temperatures in January and February, according to the World Meteorological Organization (WMO ).

The heat was particularly intense in very northern latitudes, and concentrations of the gases responsible for climate change crossed the symbolic threshold of 400 parts per million in the first two months of the year.

In that same period, the extent of sea ice in the Arctic was the smallest ever recorded by satellite, according to NASA and the United States' National Oceanic and Atmospheric Administration (NOAA).

"The temperature of the Earth is currently 1 degree Celsius higher than at the beginning of the 20th century. We are halfway to the critical threshold of 2 degrees and it is possible that national plans on climate change will not be enough to prevent a 3 degree increase, ”warned WMO Secretary General Petteri Taalas, offering this data.

Urgent measures

He considered that the most serious situations could still be avoided with urgent and far-reaching measures to reduce carbon dioxide emissions.

For his part, David Carlson, the director of the World Climate Research Program, co-sponsored by the WMO, said that "the surprisingly high temperatures that have been recorded so far in 2016 are causing a stir in the climate scientific community."

2015, unprecedented temperatures: repercussions

Already the year 2015 made history with unprecedented high temperatures, intense heat waves, abundant rainfall, severe droughts and exceptional activity from tropical cyclones.

As for heat waves, the most serious occurred in India and Pakistan, and related to this Asia and South America had the warmest year on record, while in Europe there were prolonged events of this type.

On the other hand, the droughts had a disastrous effect on the northeast of Brazil, Colombia and Venezuela, where they also affected agriculture and the water and energy sectors.

Certain areas of the Caribbean and Central America were also severely affected, while southern Africa had the worst drought since 1932-1933.

The number of tropical storms, cyclones, and typhoons was close to average, but several of these events were rare, such as Hurricane “Patricia,” which hit Mexico in October.

It was the most powerful for which data are available in the Atlantic basin and the eastern North Pacific basin, with maximum wind speeds of 346 kilometers per hour.

In relation to the increase in temperature, records were reached both at the level of the land and sea surface, which caused the sea level to continue rising and the reduction of sea ice.

93% of the excess heat on the planet is trapped in the oceans to a depth of 2,000 meters.
