Rendered Uninhabitable by Heat

Rendered Uninhabitable by Heat — It’s Not Just Sudan, Parts From North Africa to the Middle East are Under the Gun

“North Africa is already hot and is strongly increasing in temperature. At some point in this century, part of the region will become uninhabitable.” — Dr. Johannes Lilieveld
“The number of climate refugees could increase dramatically in future. Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised.” — The Max Planck Institute

Heatwaves so hot that it’s impossible to perform any activity outdoors without threat of injury or worse. Raging dust storms that make the very air unbreathable. Massive droughts that wreck agricultural productivity and biodiversity altogether. Sections of Africa and the Middle East are currently getting a taste of these new, dangerous climate conditions. But their frequency could increase by five fold or more over the next 30-40 years — threatening harm, government collapse, and the forced dislocation of millions.
Sudan Could be Made Uninhabitable by Climate Change
Due to human-caused warming, these kinds of events are already happening in places like Sudan with increasing frequency. And a recent report by CNN shows that this North African state is under threat of becoming uninhabitable to human beings due to climate change.

Drought has impacted agriculture to the extent that 1.9 million people in this nation of 40 million could face hunger over the next couple of years. A further 3.2 million face water shortages. And in the ironic juxtaposition that often comes with climate change — since 2013 about 600,000 people have been displaced due to the deluges that have more and more often come at the end of the long, dry periods.
For Sudan, the problems are just beginning. By mid-Century surface temperatures in the region could warm by between 1.1 and 3.1 degrees Celsius. And so much additional warming will multiply the occurrence of the kinds of harmful heatwaves, droughts, and dust storms that are happening today many times over. In the end, Sudan is at risk of being abandoned as its lands are taken in by a climate unfit for human habitation.
500 Million People Under Extreme Heat and Drought in Africa and Middle East by mid-Century
But it’s not just Sudan that’s facing a flip into nation-wrecking climate conditions. By 2050, extreme heat related events will be happening five times more frequently as the Earth warms up along a desiccating crescent in Africa and onward throughout a good chunk of the Middle East. During summers, by mid Century, temperatures throughout this vulnerable zone could be as much as 5 degrees Celsius hotter than they are today.

Including Sudan, more than 500 million people live in this region. And according to the Max-Planck Institute, extremely hot days — of which there were 16 each year within this vulnerable area from 1986 to 2005 — will increase five-fold to 80 by 2050 and up to 118 to 200 by 2100.
Added extraordinary and persistent heat will bake moisture out of soils, ruin forests, and advance deserts. It will produce days when wet bulb temperatures approach or exceed the limit of human endurance (35 C) time and time again. Such a high prevalence and intensity of adverse conditions will make the current problems faced by the region seem mild and moderate by comparison. In the end, numerous places are likely to become basically unlivable.
Call For Action
Given the coming hardship and what is likely to be a preventable mass migration, scientists and environmentalists are calling for action. CNN and others have highlighted a need for aid to Africa and the Middle East. But as helpful as aid is to those desperate and struggling to survive, the primary driver of the whole problem is human-based fossil fuel emissions. And unless that stops, this region and its highly vulnerable peoples, among others around the world, will be very hard hit.
Michelle Yonetani, a senior advisor on disasters from the Internal Displacement Monitoring Center noted that encouraging governments to increase commitments to act on climate is “perhaps one of the most indirect ways [to help], but [it is] globally the most important. Now really is the time to push governments to act…” Otherwise, vast regions within Africa and the Middle East face destabilization, collapse, and mass migration over rather short time horizons.

Geert Mak Pleit Nu Voor Vriendschap met Rusland

Ik kwam zojuist mijn oude vriend, de bestseller-auteur en mainstream-opiniemaker Geert Mak in de regen op straat tegen. Na elkaar te hebben begroet, vertelde Geert mij dat hij van oordeel is dat Europa zo snel mogelijk met Rusland om de tafel moet gaan zitten, om de opgelopen spanningen te deëscaleren. De VS heeft heel andere belangen dan 'wij,' aldus Mak, die benadrukte dat de macht van 'onze' Atlantische bondgenoot ingrijpend aan het afnemen is. Kortom, ik hoorde wat ikzelf al enige jaren op mijn weblog schrijf. Opvallend hoe een Nederlandse opiniemaker binnen zo'n betrekkelijk korte tijd zo wezenlijk van oordeel kan veranderen.  Immers, Mak’s gevaarlijke anti-Rusland hetze was een treffend voorbeeld van zijn opportunisme. Mei 2014 beweerde op de Hilversumse televisie de zogeheten ‘chroniqueur van Amsterdam, Nederland, Europa en de VS,’ dat er sprake was van een 'Russische gevaar,’ aangezien ‘meneer Poetin’ aan ‘landjepik’ deed en dat de Russische president d…

Native American Rape Survivors

A sign marks the entrance to White Earth Indian Reservation in Mahnomen County, Minn. (J. Stephen Conn / CC 2.0) WHITE EARTH RESERVATION, Minn.—Candice (not her real name) awoke with a start. Someone was pulling down her sweatpants. It was a male friend. “Stop!” she shouted. He kept groping her. She kicked him and he fell off the bed. She dashed out of the bedroom, tripping and tumbling down the stairs. Gripped with fear, she heard his footsteps behind her in the dark and forced herself to stand upright as she staggered out to the porch. Candice was still intoxicated. She got into her car and drove into a ditch. A white police officer pulled up. She struggled to hold back tears as she told him about the attempted rape. All the officer saw was a drunk and disorderly Native American woman. He dismissed Candice’s report of sexual assault as a lie she had made up to avoid getting a DUI. He did not take her to the hospital for a forensic exam. The sexual assault was not recorded in his pol…
