Europe is already struggling to absorb an influx of refugees from war-torn Syria, Afghanistan, Iraq, and Africa. Germany alone has taken in more than a million people since 2015. This wave of immigration has led to political upheaval, with the rise of right-wing political parties in Germany, Poland, Austria, and Hungary, among others. Now a new study, published in the journal Science, shows that the current surge in refugees may just be a preview of what's to come due in large part to global warming. From a report: At an average growing season temperature of about 68 Fahrenheit, which is the optimum one for agriculture, the number of applications for asylum was lowest. As the average temperature rose, so did the number of people from Somalia, Bangladesh and other warmer climate countries seeking asylum. But when cooler countries -- such as Serbia and Peru -- got warmer, fewer applications were received. The acceptance rate for asylum application to the EU is less than 10%. But when there was a spike in applications tied to weather fluctuations, the admittance rate rose to about 30%, suggesting agencies who evaluate the applicants find their cause worthy.
