The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures towards increasingly dangerous levels, according to a new report from the World Meteorological Organization.
The WMO Statement on the State of the Global Climate in 2018, its 25th anniversary edition, highlights record sea level rise, as well as exceptionally high land and ocean temperatures over the past four years. This warming trend has lasted since the start of this century and is expected to continue.
“The data released in this report give cause for great concern. The past four years were the warmest on record, with the global average surface temperature in 2018 approximately 1°C above the pre-industrial baseline,” notes UN Secretary General António Guterres.
“These data confirm the urgency of climate action. This was also emphasized by the recent Intergovernmental Panel on Climate Change (IPCC) special report on the impacts of global warming of 1.5°C. The IPCC found that limiting global warming to 1.5°C will require rapid and far reaching transitions in land, energy, industry, buildings, transport and cities and that global net human-caused emissions of carbon dioxide need to fall by about 45% from 2010 levels by 2030, reaching net zero around 2050,” Guterres wrote in the report.
“There is no longer any time for delay.”
