The Heat Age

This April was the hottest April on record, globally, for at least 130 years, and the past twelve months was the hottest 12-month period since measurements began. Those who oppose the science of global warming should recognize that there is nothing to oppose: for the past 35 years, global warming has unfolded as predicted by science.

BERLIN – This April was the hottest April on record, globally, for at least 130 years, according to the worldwide temperature records maintained by NASA and the US National Oceanic and Atmospheric Administration (NOAA). The past twelve months was the hottest 12-month period since measurements began.

That is what the data from weather stations and ships show. But if you prefer satellite data, the picture is similar. Satellite data have this March the hottest March on record, with April ranking second-hottest; the surface data have it the other way round, with March the second-hottest and April the hottest.

Of course, more important, scientifically, are the long-term trends. For the past 30 years – that’s how long the satellite measurements have been taken – the trend is clearly upward and similar in magnitude in all the available data sets.
