This junk again? ‘Hotter temperatures will accelerate migration of asylum-seekers to Europe’

Don’t these people ever learn from past mistakes? Apparently not. from COLUMBIA UNIVERSITY and the “50 million climate refugees by 2010 that never happened so they had to disappear it” department.

Hotter temperatures will accelerate migration of asylum-seekers to Europe, says study

EU could face a massive influx by 2100 if carbon emissions hold steady

New research predicts that migrants applying for asylum in the European Union will nearly triple over the average of the last 15 years by 2100 if carbon emissions continue on their current path. The study suggests that cutting emissions could partially stem the tide, but even under an optimistic scenario, Europe could see asylum applications rise by at least a quarter. The study appears today in the journal Science.

“Europe is already conflicted about how many refugees to admit,” said the study’s senior author, Wolfram Schlenker, an economist at Columbia University’s School of International and Public Affairs (SIPA) and a professor at the university’s Earth Institute. “Though poorer countries in hotter regions are most vulnerable to climate change, our findings highlight the extent to which countries are interlinked, and Europe will see increasing numbers of desperate people fleeing their home countries.”

Schlenker and study coauthor Anouch Missirian, a Ph.D. candidate at SIPA, compared asylum applications to the EU filed from 103 countries between 2000 and 2014, with temperature variations in the applicants’ home countries. They found that the more temperatures over each country’s agricultural region deviated from 20 degrees Celsius (68 degrees Fahrenheit) during its growing season, the more likely people were to seek refuge abroad. Crops grow best at an average temperature of 20 degrees C, and so not surprisingly, hotter than normal temperatures increased asylum applications in hotter places, such as Iraq and Pakistan, and lowered them in colder places such as Serbia and Peru.

Combining the asylum-application data with projections of future warming, the researchers found that an increase of average global temperatures of 1.8 °C — an optimistic scenario in which carbon emissions flatten globally in the next few decades and then decline — would increase applications by 28 percent by 2100, translating into 98,000 extra applications to the EU each year. If carbon emissions continue on their current trajectory, with global temperatures rising by 2.6 C to 4.8°C by 2100, applications could increase by 188 percent, leading to an extra 660,000 applications filed each year.

Under the landmark climate deal struck in Paris in 2015, most of the world’s nations agreed to cut carbon emissions to limit warming by 2100 to 2°C above pre-industrial levels. President Trump’s recent decision to withdraw the United States, the world’s second largest carbon emitter, from the accord now jeopardizes that goal.

In a further setback to reducing U.S. carbon emissions, the U.S Environmental Protection Agency has proposed lowering the U.S. government’s “social cost” of carbon, or the estimated cost of sea-level rise, lower crop yields, and other climate-change related economic damages, from $42 per ton by 2020 to a low of $1 per ton. The EPA partly arrived at the lower figure by excluding the cost of U.S. emissions on other countries, yet as the study shows, effects in developing countries have clear spillovers on developed countries. “In the end, a failure to plan adequately for climate change by taking the full cost of carbon dioxide emissions into account will prove far more costly,” said Missirian, a fourth-year sustainable development major.

The research adds to a growing body of evidence that weather shocks can destabilize societies, stoke conflict and force people to flee their home countries. In a widely-cited 2011 study in Nature, a team of researchers led by Solomon Hsiang, then a graduate student at SIPA, linked modern El Niño drought cycles to increased violence and war globally.

More recently, researchers have highlighted the connection between the drying of the Middle East and ongoing conflict there. In a 2015 study in the Proceedings of the National Academy of Sciences, another team of Columbia researchers made the case that climate change made Syria’s 2006-2010 drought two to three times more likely, and that the drought was a catalyst for Syria’s 2011 uprising. The civil war that followed has so far claimed 500,000 lives, by one estimate, and forced 5.4 million Syrians to flee the country.

Germany has taken in the largest share of asylum-seekers from Syria and elsewhere, but increasingly faces a backlash from German voters worried about assimilation and loss of jobs. A wave of anti-immigrant sentiment elsewhere in Europe has led to Hungary building a wall to keep refugees out and influenced Great Britain’s decision to leave the European Union. In the United States, President Trump was elected in part on his promise to build a wall to block Mexican immigrants from entering the country illegally.

Hsiang, now an economics professor at the University of California, Berkeley, who was not involved in the research, called the study an “incredibly important” wakeup call. “We will need to build new institutions and systems to manage this steady flow of asylum seekers,” he said. “As we have seen from recent experience in Europe, there are tremendous costs, both for refugees and their hosts, when we are caught flat footed. We should plan ahead and prepare.”

Colin Kelley, a climate scientist at Columbia’s International Research Institute for Climate and Society who linked climate change to Syria’s ongoing conflict, also praised the research. “It’s unclear how much more warming will occur between now and the end of the century, but the study clearly demonstrates just how much climate change acts as a threat multiplier. Wealthier countries can expect to feel the direct and indirect effects of weather shocks from manmade climate change in poorer, less resilient countries.”

The research was initiated at the request of the European Commission’s Joint Research Centre (JRC), which also provided funding. “These findings will be especially important to policymakers since they show that climate impacts can go beyond the borders of a single country by possibly driving higher migration flows,” said Juan-Carlos Ciscar, a senior expert at the JRC’s Economics of Climate Change, Energy and Transport Unit. “Further research should look at ways for developing countries to adapt their agricultural practices to climate change.”

There’s already a huge influx of Muslims into the EU, which has nothing to do with climate change, but I’m sure they will count them anyway.

Here is the study, if you want to waste your time reading it: http://science.sciencemag.org/content/358/6370/1610

Statistican William Briggs has already called out the paper for it’s statistical stupidity. He writes:

It is the dumbest, most idiotic use of statistics I have seen in over a decade. (And I have seen a lot.)

You have to possess a near-miraculous view of statistics, and a complete ignorance of politics, to have suggested or believe in this model. How come asylum applications aren’t swelling in chilly Chili [sic!]? They had, say, 6,000 years of history to draw upon yet they chose only the last fifteen? And they believe the hideously complex political relationship between Europe and (largely) the Levant can be described by quantifying each country’s “corruption index”? I despair.

…

Physically the study makes no sense, either. A handful of minor temperature changes is not what is driving asylum applications, as even a cursory reading of the daily headlines shows. To claim one has found a “non-linear” *causative* relationship in so short of record is absurd. These fellows ought to crack open a history book or two (written before this century).
