Climate change records remind us thermostat is steadily pushing up


N

ew climate change records have come along to remind us that Earth’s thermostat is steadily pushing upward.

More exactly, there are two global high temperature records and a smattering of climate change low points.

March 2015 was the warmest March since record-keeping began in 1880, says the National Oceanic and Atmospheric Administration. And the first quarter of 2015 was the warmest first quarter on record in those same 136 years.

That gives 2015 a stab at trumping the hottest year on record — which was 2014.

The uninterrupted continuation of the warming trend is no surprise. The 10 warmest years on record have occurred in the past 17 years.

And though the rise in the last 10 years has been gentle by comparison, since 1910, the clear trend has been up, according to NASA’s Global Land-Ocean Temperature Index.
