Another month, another global heat record that has left climate scientists scratching their heads and hoping this is an El Niño-related hangover rather than a symptom of worse-than-expected planetary health.
Global surface temperatures in March were 0.1C higher than the previous record for the month, set in 2016, and 1.68C higher than the pre-industrial average, according to data released on Tuesday by the Copernicus Climate Change Service.
This is the 10th consecutive monthly record in a warming phase that has shattered all previous records. Over the past 12 months, average global temperatures have been 1.58C above pre-industrial levels.
This, at least temporarily, exceeds the 1.5C benchmark set as a target in the Paris climate agreement but that landmark deal will not be considered breached unless this trend continues on a decadal scale.
The UK Met Office previously predicted the 1.5C goal could be surpassed over the period of a year and other leading climate monitoring organisations said the current levels of heating remain within the bounds anticipated by computer models.
However the sharp increase in temperatures over the past year has surprised many scientists, and prompted concerns about a possible acceleration of heating.
Diana Ürge-Vorsatz, one of the vice-chairs of the UN’s Intergovernmental Panel on Climate Change (IPCC), noted the planet has been warming at a pace of 0.3C per decade over the past 15 years, almost double the 0.18C per decade trend since the 1970s. “Is this within the range of climate variability or signal of accelerated warming? My concern is it might be too late if we just wait to see,” she tweeted.

If we discover this trend of rising temperatures is an acceleration rather than a natural fluctuation, would it change your view on the urgency of addressing climate change?

How would you feel about the future of our planet if we continue to break global heat records every month?

True science is the ability to replicate something over and over getting the same result. Climate ‘science’ isn’t that.
It’s a bunch of predictions based on sketchy models that have never come true. Science is about proof, not belief.. ie people believe the earth is flat.

Knowing that we've temporarily exceeded the 1.5C global warming target set by the Paris climate agreement, how do you think countries should respond?
