The WMO's Provisional Statement on the State of the Global Climate in 2019 was released Tuesday on the second day of the COP25 UN climate change conference in Madrid. The report found that the mean temperatures for January through October 2019 were around 1.1 degrees Celsius above pre-industrial levels, and that 2019 would likely be the second or third warmest year on record, meaning the past five years "are now almost certain" to be the five warmest years on the books.
"It's shocking how much climate change in 2019 has already led to lives lost, poor health, food insecurity and displaced populations," Dr. Joanna House of the University of Bristol told BBC News, in response to the report's release. "Even as a climate scientist who knows the evidence and the projections, I find this deeply upsetting. What is more shocking is how long very little has been done about this. We have the information, the solutions, what we need now is urgent action."
Since the 1980s, every decade has been warmer than the one before, but just reciting average temperature increases doesn't give a true sense of the impact of global warming, University of Manchester atmospheric physics professor Grant Allen told The Guardian.
"This [temperature rise] does not simply mean slightly warmer summers, it means an increased frequency of extreme weather globally - droughts, heatwaves, flooding and changing patterns in the frequency and intensity of tropical cyclones," Allen said. "These impacts are real and happening now and place huge pressures on communities and countries - put simply, these impacts make for a more unstable world, and are already having profound impacts on our ecosystems and biodiversity."
