Hurricanes blew away Puerto Rico's power grid. Now solar power is rising to fill the void.

More than three months after Hurricanes Maria and Irma slammed their island, over a million Puerto Ricans are still without reliable power. But one recent day, Rosa López and José Quiñones finally left those ranks.

It happened when four technicians installed a Tesla Powerwall solar battery pack onto a wall in their suburban San Juan home — a 275-pound white metal beast that can store enough electricity to keep a house running from sunset to sunrise.

Summary: Climate scientists say that killer heat waves will become increasingly prevalent in many regions as climate warms. However, most projections leave out a major factor that could worsen things: humidity, which can greatly magnify the effects of heat alone. Now, a new global study projects that in coming decades the effects of high humidity in many areas will dramatically increase.

Climate change made the torrential rains that flooded Houston after Hurricane Harvey last summer much worse, scientists reported Wednesday.

Two research groups found that the record rainfall as Harvey stalled over Texas in late August, which totaled more than 50 inches in some areas, was as much as 38 percent higher than would be expected in a world that was not warming.

While many scientists had said at the time that Harvey was probably affected by climate change, because warmer air holds more moisture, the size of the increase surprised some.

theatlantic.com - Marina Koren - September 18th 2017

The Caribbean is preparing for another “dangerous” major hurricane less than two weeks after Irma struck the region, devastating entire islands, flattening homes and buildings, and killing more than 30 people.

The National Hurricane Center on Monday upgraded Hurricane Maria to a Category 3 storm packing 120-mile-per-hour winds with stronger gusts. “Additional rapid strengthening is forecast during the next 48 hours, and Maria is expected to be a dangerous major hurricane as it moves through the Leeward Islands and the northeastern Caribbean Sea,” the center said in its latest advisory.

At least 60 people have been killed in huge forest fires in central Portugal, many dying in their cars as they tried to flee the flames . . .

 . . . Several hundred firefighters and 160 vehicles were dispatched late on Saturday to tackle the fire, which broke out in the municipality of Pedrógão Grande before spreading fast . . . 

 . . . The Iberian peninsular is sweltering under a severe heatwave, with temperatures exceeding 40C (104F) in some regions.

About 60 forest fires took hold across Portugal on Saturday night, with 1,700 firefighters battling to put them out.

Weather Disasters Can Fuel War in Volatile Countries

            

African countries like Uganda are among the world's most ethnically diverse, and they are also vulnerable to climate change. New findings suggest peace will be harder to achieve and maintain in places like Uganda as the climate changes.

Droughts and other extremes can cause dangerous economic shocks

scientificamerican.com - by John Upton - July 26, 2016

Following the warmest two years on record and spikes in violence that fueled a global refugee crisis, climate scientists on Monday reported that armed fighting is prone to follow droughts, heatwaves and other weather-related calamities in turbulent countries. . . 

. . . Donges and three other European researchers detected the pattern after analyzing extreme weather events that inflicted heavy economic damages, and outbreaks of fighting that left at least 25 dead in a year. The results were published in Proceedings of the National Academy of Sciences.

Climate Change Accelerating At 'Unprecedented' Rate

A new report from the World Meteorological Organization (WMO) suggests global climate change is advancing at an alarming and "unprecedented" rate.

Last year's extreme weather broke a series of records, including global temperatures, exceptional rainfall, devastating droughts, unusual cyclone activity and intense heat waves. And while 2015 proved to be the warmest year worldwide, 2016 is expected to far exceed those records.

After severe flooding and shock tornadoes, now is time get serious about precautionary steps to counter climate impacts says UN disaster chief

climatechangenews.com - by Alex Pashley - December 30, 2015

Governments have been told to face a “new abnormal” of extreme weather after a wave of natural disasters wrought death and economic damage around the world in recent days.

Heavy flooding in Britain and South America, and devastating tornadoes in the US has laid bare the lack of official preventative measures, Margareta Wahlstrom, head of the UN’s disaster risk reduction agency said on Tuesday.

They highlighted how climate change-linked events were becoming harder to predict as the planet overheats, she said.

Implementing an UN-backed framework to protect people against climate impacts agreed by 187 states earlier this year was “critical”, the official at the Geneva-based agency said.

El Niño Strengthens Amid Warning Millions Could Face Hunger and Disease

             

Sea surface temperatures in October -- orange-red colors are above normal.

cnn.com - by Brandon Miller and Nick Thompson - December 30, 2015

If you're wondering why your white Christmas didn't arrive as scheduled this year, meteorologists have a two-word answer: El Niño.

This year's El Niño weather event -- characterized by warming waters in the eastern Pacific Ocean -- is already one of the three strongest ever recorded. NASA says El Niño conditions are still strengthening, and it could even rival the intensity of the record 1997 event that wreaked worldwide weather havoc.
