In true global warming, the whole worlds warms up. A common argument against global warming is that the climate has always varied in any particular place or time. For this argument to be true if it warms up one place, some place it cools down on average. However, Svante Björck, a climate researcher at Lund University in Sweden, has now shown that global warming, i.e. simultaneous warming events in the northern and southern hemispheres, have not occurred in the past 20,000 years, which is as far back as it is possible to analyze with sufficient precision to compare with modern developments. Svante Björck’s study thus goes 14,000 years further back in time than previous studies have done. He eventually claims that the current global warming trend is unique in this time frame.
