A year of record global heat has pushed Earth closer to dangerous threshold
Temperatures surpassed the 1.5-degree Celsius warming threshold over the past year, and scientists warn they will again soon.
The data released by European climate scientists showed May was the 12th consecutive month during which average global temperatures surpassed all observations since 1850, and probably any extended period for more than 100,000 years. Over the past year, according to the European Union’s Copernicus Climate Change Service, global temperatures averaged 1.6 degrees Celsius (2.9 degrees Fahrenheit) above preindustrial levels. Under the landmark 2015 Paris agreement, the world’s leaders pledged to hold Earth’s temperature rise “to well below” 2 degrees C (3.6 degrees F) above pre-industrial levels and pursue efforts “to limit the temperature increase” to 1.5 degrees C above pre-industrial levels, to avert some of the worst effects of global warming. The fact that the planet surpassed 1.5 degrees C for one year does not amount to a permanent shift, but it comes as scientists are warning that it is likely to happen again — within a few years. The World Meteorological Organization said that it is highly likely that, for at least one calendar year in the next five, temperatures will exceed 1.5 degrees C above preindustrial levels once more.
