Well, the coldest March on record was in 1962, when the mean temperature staggered to just 1.9C.
Global mean temperature varied within a range of one degree Celsius during the Holocene.
That record will not be broken this year, but the more recent cold March of 1987 looks under threat - its mean temperature was 3.3C.
The mean temperature by 2070, perhaps earlier, will be higher than it has been since the human species evolved, according to the Nature article.
The Met Office said that from 1 March to 26 March the UK mean temperature was 2.5C, which is three degrees below the long-term average.
The main reason for the low temperatures in spring was a colder than usual March, which had a mean temperature of 2.2C to 3.3C below the long-term average.
Arrhenius predicted that if the carbon dioxide concentration increased, the mean temperature of the surface of the earth would increase, in pretty much the way he said it would.
FORBES: NASA Data Pit Scientific Method Against Climate Astrology
As it currently stands, the UN Framework Convention on Climate Change has set a target of limiting the rise in global mean temperature to 2C (3.6F) above pre-industrial levels.
Since then, the concentration of carbon dioxide has in fact increased and the mean temperature of the surface of the earth has increased in pretty much the way Dr. Arrhenius said it would.
FORBES: NASA Data Pit Scientific Method Against Climate Astrology
Writing in the Journal Nature in April, researchers said pledges made at December's UN summit in Copenhagen are unlikely to keep the rise in the global mean temperature to 2C (3.6F) above pre-industrial levels.
It presupposes that there is such a thing in a chaotic system as a "global climate" from which a global mean temperature can be calculated and that it can in any way measurable with any accuracy.
In The Wall Street Journal opinions section, a group of 16 scientists, including former professors and chiefs of several atmospheric research institutes, have argued boldly that global warming is no cause for panic, claiming that the mean temperature of the Earth has not changed for more than a decade.
Plant ecologists know that the northern limit of the forest is determined by the mean July temperature.
FORBES: Global Warming: Hotheads, Flatliners and Lukewarmers, Part One
The five-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow down in the growth rate of net climate forcing.
FORBES: Yes! We Should Defund The U.N.'s Intergovernmental Panel On Climate Change
Cynics might note that this would mean the temperature changing more dramatically in the next 100 years than it has done in any such period over the past 20, 000 years, though the scientists say that is precisely the point.
The cold waters mean a large temperature contrast between the land and ocean -- conditions that favor the formation of a strong inversion layer that traps smog over cities, such as the Los Angeles, Calif.
Some cars get hotter than 150 degrees inside when parked in the sun, so reducing the temperature could mean Toyota could use a smaller AC unit, he added.
But keeping the temperature rise below 2C will mean adopting a wide range of measures - as the committee puts it, there is "no magic bullet".

Dipping a toe in market waters however pleasant the temperature might be doesn't mean these two countries can count on private investors to keep them fully financed the day after they exit their bailouts.
One model which materialists use for their reductive view of consciousness is from physics: for instance, in the reduction of thermodynamics to statistical mechanics, the temperature of a gas is explained in terms of the mean kinetic energy of its constituent molecules.
