Climate change is man-made shows arctic research
New research shows that the temperature of the arctic region fell steadily from over 2000 years ago all the way up to a 100 years ago. The cooling was caused by less solar radiation during the summer and the cold temperatures would have continued undisturbed. But around the year 1900 there occured a dramatic increase in temperature and the new research results therefore provide further evidence of man’s influence on the climate. The results are published in the scientific journal, Science.
