*EXTREMELY HOT DAYS*  are all in the works; extremely hot days are expected to become much more frequent.......

Here then is the Trajectory for a world of sweltering days.

PARIS : DEVASTATING OCEAN HEATWAVES ON THE RISE : Yes, ocean heatwaves which can have ''devastating and long-term impacts'' -

On Ecosystems have become longer and more frequent over the past century, according to an international study published this very Tuesday.

From 1925 to 2016, the number of annual marine heatwave days globally jumped by 54 percent, with a noticeable acceleration over the last three decades, a paper in the Journal Nature Communications said.

Similar to an atmospheric heatwave, a marine heatwave is a prolonged period of unusually warm water.

''While some of us may enjoy the warmer waters when we go swimming, these heatwaves have significant impacts on ecosystems, biodiversity, fisheries, tourism and aquaculture,'' said the study's lead author Eric Oliver from Dalhousie University, Canada.

''There are often profound economic consequences that go hand in hand with these events.''

The heatwaves are linked to an overall rise in average sea surface temperatures consistent with climate change effects, the study found.

Extremely hot days, when temperatures soar to 95 degrees Fahrenheit or higher, can be miserable.

Crops wilt in the fields. Electric grids strain to keep pace with demand. People are at greater risk of dying. And those hot temperatures are expected to be much more frequent in the coming decades.

One map, based on a new analysis from from the Climate impact Lab, shows how 95-degrees days [35 degrees Celsius] are expected to multiply this century if countries take only moderate climate action.

In this scenario, countries would take some measures, but not drastic ones, to curb emissions - roughly the trajectory of the pledges under the Paris climate agreement.

Despite the measures, global warming could significant shifts for many cities. In Washington, from 1986 to 2005,  an average of seven days each year had temperatures of at least 95 degrees.

By the end of the century, the city can expect 29 of these extremely hot days per year., on average, {The range is 14 to 46 hot days per year}.

Phoenix is used to the heat, averaging 124 days per year with 95-degree weather.

At the end of the century, that's expected to increase to around 155 days - an extra month of extreme temperatures each year. Madrid would go from eight severely hot days per year to 43 -

Beijing from 9 to 35.

The swings are even greater closer to the Equator. New Delhi, India's capital city, has historically averaged 105 days with temperatures of at least 95 degrees each year.

If the world's nations took no action on global warming, and emissions continued to rise at the same pace they did in the first decade of this century - with total global warming of 7.2 degrees Fahrenheit or more by the end of the century -

Extremely hot days would become much more commonplace.

By 2100, Washington could swelter in 95-degrees weather about 74 days, on average.

Large swaths of  Brazil and sub Saharan Africa would experience these temperatures for most of the year.

The worst-case for global warming now appears less likely as global coal use declines and nations slowly move toward cleaner energy.

In the United States, electricity use soars as temperatures rise and more households use air-conditioning more frequently.

One recent report found that the United States electric grid would have to handle a 7.2 percent increase in peak demand this century under a moderate warming scenario.

The  Honor and Serving of the latest Operational Research on *climate changes* continues. And the World students Society thanks researchers and authors Brad Plumer and Nadja Popvich.
