CEM REPORT, ENVIRONMENT | Global temperatures are likely to surge to record levels in the next five years, fuelled by heat-trapping greenhouse gases and a naturally occurring El Niño weather pattern, according to a new update issued by the World Meteorological Organization (WMO) on Wednesday.
There is a 66 per cent likelihood that the annual average near-surface global temperature between 2023 and 2027, will be more than 1.5°C above pre-industrial levels for at least one year.
And there is a 98 per cent likelihood that at least one of the next five years, and the five-year period, will be the warmest on record.
“A warming El Niño is expected to develop in the coming months and this will combine with human-induced climate change to push global temperatures into uncharted territory,” he said.
“This will have far-reaching repercussions for health, food security, water management and the environment. We need to be prepared,” said Petteri Taalas.
In addition to increasing global temperatures, human-induced greenhouse gases are leading to more ocean heating and acidification, sea ice and glacier melt, sea level rise and more extreme weather.
The Paris Agreement sets long-term goals to guide all nations to substantially reduce global greenhouse gas emissions to limit the global temperature increase in this century to 2°C while pursuing efforts to limit the increase even further to 1.5°C, to avoid or reduce adverse impacts and related losses and damages.
The Intergovernmental Panel on Climate Change says that climate-related risks for global warming are higher than 1.5 °C but lower than 2 °C.
The new report was released ahead of the World Meteorological Congress (22 May to 2 June) which will discuss how to strengthen weather and climate services to support climate change adaptation.
Priorities for discussion at Congress include the UN’s Early Warnings for All initiative to protect people from increasingly extreme weather and a new Greenhouse Gas Monitoring Infrastructure to inform climate mitigation.
