Opinion | Heat and Humidity Are a Killer Combination – By Ethan Coffel, Radley Horton and Colin Raymond – NYT

I am sorry to report that there is some very bad news for Vietnam and Southeast Asia in this science report from the NYT.

I predicted in 2014, that in the next five years, the US would get serious and wake up about climate change. Unfortunately, this scientific news will help the prediction. It also explains yesterday. Connecticut had high humidity and high temperature, which explains why playing tennis in the late afternoon and then morris dancing made me feel severly exhausted.

The authors are climate scientists at Dartmouth College and Columbia University.

“After enduring another scorching summer — the fourth-hottest on record for the contiguous United States — it may be hard to imagine conditions getting much worse. But as a new report from the United Nations’ panel on climate change warns, we are locked in to additional warming and other changes like sea level rise. And we are running out of time to avert potentially catastrophic outcomes.

One critically important and underreported fact is that as temperatures rise, absolute humidity, the total amount of moisture in the air, will also increase. That may create combinations of heat and humidity so extreme that the evaporation of human sweat won’t sufficiently cool our bodies, leaving even healthy adults at risk of death from overheating.

Our research suggests that in about 50 years, these deadly conditions — almost unknown on the planet today — could occur once per decade in parts of the world. Millions of people could be exposed to these extreme conditions if greenhouse gas emissions continue to rise following historical trends.”

Why the Wilder Storms? It’s a ‘Loaded Dice’ Problem – By Somini Sengupta -NYT

“Torrential rainfall lashed Japan in July. A cloudburst in August submerged entire villages in south India. In September, Hurricane Florence burst dams and lagoons, with coal ash and pig waste spilling into the waterways of North Carolina. On the other side of the planet, a typhoon walloped the Philippines and ravaged the country’s staple crop, rice.

Climate scientists can’t say where or when the next big storm will hit, but all the evidence points to this: Global warming is bringing the planet into an era of wilder, more dangerous rains with ruinous and long-lasting consequences.

“Where it rains, it’s raining heavier,” said Raghu Murtugudde, a professor of Earth systems science at the University of Maryland who edited a recent book on extreme weather in the tropics. “It’s the classic loaded-dice analogy.”

The dice, he said, are “throwing up some numbers more often” in the form of extreme weather. How? The greenhouse gases humans have already injected into the atmosphere have heated up the planet and now pack so much moisture into the air that they heighten the risk of more extreme precipitation.”

David Lindsay:   Bravo Somini Sengupta. Based on her article above,  please join environmentalists like myself in funding a Blue wave to clean the Augean Stables, which in now represented by the Republican controlled U S Congress and Presidency. The easiest way to support science based progressives is to donate to the DSCC.org, the DCCC.org, or political funding groups like Emily’s List.

Deadly Tensions Rise as India’s Water Supply Runs Dangerously Low – The New York Times

By Maria Abi-Habib and Hari Kumar

“SHIMLA, India — The people of Shimla haven’t agreed on much lately. A drought in the Himalayan resort has had residents blaming farmers, the tourism industry and one another for depleting the strained water supplies.

And everyone’s been angry at the key men.

Shimla’s decrepit network of water pipes, built under British colonial rule more than 70 years ago, depends on the civil servants known as key men to open and close the valves that supply each neighborhood. The current shortage, which in May left some homes without water for 20 days, has led to such fury toward the key men — accused, in just about every neighborhood, of depriving it of its fair share — that a court ordered police protection for them.

“I was getting angry phone calls calling me everything — stupid, worthless — at one or two in the morning,” said Inder Singh, 44, who has been a key man for 24 years. “I would be mobbed by dozens as I was trying to leave my home for work,” he said, inserting his key — a meter-long metal contraption — into the ground to open a valve.

Tourism is the mainstay of the economy in this mountain city, which the British colonial authorities made their summer capital so they could escape the brutal heat of New Delhi. But the drought — accompanied by unusually high temperatures, above 90 degrees Fahrenheit — has been so severe that in May, some residents took to Twitter to ask tourists to stay away and leave the water for local residents. Many in Shimla call it the worst shortage they can remember.”

Yes, thank you  Maria Abi-Habib and Hari Kumar and the NYT for excellent reporting. Here are some of the NYT comments I recommeded:

Mr. Reeee

This is ALL about overpopulation.

Here is a prime example of overpopulation creating conditions where dwindling resources are strained to the breaking point.

About the only solutions are massive desalinization projects or cutting the population.

Meanwhile, the US government has been cutting funding for programs that encourage and enable easy access to birth control across the globe.

Here’s the result. Get ready for more and more stories of similar situations involving arable land, water and food shortages and spiraling death tolls as a direct result.

Drought and climate change set the teeth of displacement in motion in Syria. Mass migration to cities like Aleppo occurred which put extreme pressure on the existing infrastructure and jobs economy. This current wave of war and atrocity in places like Syria and Sudan are initiated by drought and famine. The oil wars were bad. The water wars will be so much worse.

It’s about over population AND increasingly inappropriate and/or arcane institutional arrangements for using water. Sections of North America and the US will come to similar situations as global warming intensifies. How sad that we “intelligent” humans can know what is happening and project what will happen, but seem incapable of acting effectively to avoid the collapse of not only civilization but the biodiversity of our beautiful and unique planet.

Greed triumphs all.

Finite resource, poor climate awareness, inadequate storage, poor meteorological forecasting but the main reason is

OVERPOPULATION

They are boxed in. Expect more loss of life and livelihood, social unrest, international conflict (no transboundary river and storage management) as Kali takes her toll.

This is only the beginning. The entire region is at fault. My sympathy is running as low as their decreasing per capita water supply.

The Uninhabitable Village – by Geeta Anand and Vikram Singh – NYT Oct 26 2017

Beautiful photography, heartbreaking story:

Each sentence below has a photo video clip:

“This is S. Periyanayaki in the rice field in southern India where her husband died.

The worst drought in more than a century killed his rice crop, and he blamed himself.

A farmer found Periyanayaki’s husband, K. Suresh, lying in the barren field. He had drunk pesticide.

Hundreds of thousands of Indian farmers have killed themselves in the past 30 years, and some climate researchers believe hotter weather has driven crop failure and made the problem worse.”

Feature: Heat and drought drive south India’s farmers from fields to cities – April 2017 Reuters.com

NAGAPATTINAM, India (Thomson Reuters Foundation) – Vinod Kumar remembers a time, not so long ago, when the fields in his village in the southern state of Tamil Nadu were green all year round.

His family lived comfortably from its farmland of just over 2 acres (0.8 hectares), growing vegetables, coconuts and millet irrigated by the Cauvery river and the rain.

Kumar grew up believing the farm would be his life.

But today, the 30-year-old drives a car for a living in the city of Chennai, 250 km (155 miles) away. His family joined him two years ago, abandoning what had been for generations their home and their land.

On a recent journey back to the area where he grew up, he said he was far from the only migrant.

“At this time of year, these fields should be green with paddy shoots – but no one seems to be farming,” said Kumar, as he drove past arid fields overgrown with scrub and thorns one sweltering July afternoon.

“We haven’t had enough water for many years. It has become impossible to make a living from farming, and a lot of people have moved to cities to do other jobs.”

India drought: ‘330 million people affected’ – BBC News 20 April 2016

I am looking for evidence to support the report in the NYT last month, that 100,000 Indian farmers had committed suicide because of the drought in Southeast India.  This old article in the BBC sheds some background light on the disaster.

“At least 330 million people are affected by drought in India, the government has told the Supreme CourtAuthorities say this number is likely to rise further given that some states with water shortages have not yet submitted status reports.The drought is taking place as a heat wave extends across much of India with temperatures crossing 40C for days now.An 11-year-old girl died of heatstroke while collecting water from a village pump in the western Maharashtra state.

Yogita Desai had spent close to four hours in 42C temperatures gathering water from the pump on Sunday, local journalist Manoj Sapte told the BBC.She began vomiting after returning home and was rushed to hospital, but died early on Monday.Yogita’s death certificate says she died of heatstroke and dehydration.

The pump was a mere 500m from her house, but a typical wait for water stretches into hours.India is heavily dependant on monsoon rains, which have been poor for two years in a row.The government said that nearly 256 districts across India, home to nearly a quarter of the population were impacted by the drought.Schools have been shut in the eastern state of Orissa and more than 100 deaths due to heatstroke have been reported from across the country, including from the southern states of Telangana and Andhra Pradesh which saw more than 2,000 deaths last summer.”

A Tesla Too Pricey? E-Bikes Offer Entry-Level Electric Transportation – The New York Times

“Electric cars remain something of a novelty, commanding premium prices and presenting charging challenges, but another kind of electric vehicle has been gaining momentum: the e-bike. Globally, electric cars — battery and plug-in hybrids — account for only about 1 percent of all vehicle sales, with about 1.15 million expected to be sold worldwide this year, according to EV-volumes.com. Compare that with the 35 million e-bikes expected to be purchased this year, according to Navigant, with countries like Ger. . . “

Why China Wants to Lead on Climate- but Clings to Coal (for Now) – The New York Times

“In any event, China’s climate agenda is not so straightforward.

The country is the world’s largest coal consumer. Even as it is phasing out coal plants at home, it is building coal plants abroad as part of an ambitious “One Belt, One Road” initiative, designed to expand Chinese global influence. At the same time, China has embraced renewables: It is the largest producer of electric cars, and it has proposed to set up what would become the world’s largest carbon market.

Li Shuo, of Greenpeace China, said the projected rise in emissions would not affect China’s overall trajectory toward slowing emissions at home and stepping up diplomatically.

“China can continue to play a leading role in the global climate debate, despite this short-term increase of emissions, which is temporary,” he said.

One thing still lost in the fog of global climate negotiations is whether the Chinese leader really wants to be the global leader on climate. In his speech to the Communist Party conclave in October, Mr. Xi took a swipe at the United States by criticizing what he called “self-isolation.” But he said nothing about how his country would step up to fill the gap.

Mr. Xi has said only that China will stick to its pledges. But even if every country meets its Paris pledges, the planet is expected to heat up 3 degrees Celsius or more. That would not be enough to stave off the most catastrophic effects of climate change.”

Vulnerability- Risk Reduction- and Adaptation to Climate Change in Vietnam. World Bank .pdf

“Vietnam’slong coastline, geographic location, and diverse topography and climates contribute to its being one of the most hazard-prone countries of the Asia-Pacific region, with storms and flooding, in particular, responsible for economic and human losses.Given that a high proportion of the country’s population and economic assets (including irrigated agriculture) are located in coastal lowlands and deltas, Vietnam has been ranked among the five countries likely to be most affected by climate change. 6

You Fix It: Can You Stay Within the World’s Carbon Budget? – The New York Times

“We need to stay within our carbon budget.To prevent the worst effects of global warming, we have to keep temperatures from increasing by more than 3.6 degrees Fahrenheit (2.0 degrees Celsius) above the preindustrial level — the upper limit agreed to in the 2015 Paris climate accord.That means we can’t send more than 2,900 gigatons of CO2 into the atmosphere. This is our carbon budget.We’ve already used about 73% of our budget.

The world has emitted 2,100 gigatons of CO2 since 1870, mostly from . . .
