A common argument against global warming is that the climate has always varied. Temperatures rise sometimes and this is perfectly natural is the usual line. However, a climate researcher 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.
