Nairobi, Feb 8 – In the wake of data released by the United Nations World Meteorological Organization (WMO), showing the past four years were officially the ‘four warmest on record,’ UN Secretary-General António Guterres has called for urgent climate action and increased ambition, ahead of his climate summit in September.
His reaction on February 6 came after WMO issued a report confirming that 2015, 2016, 2017 and 2018 were the four warmest years recorded to date. The analysis, based on the monitoring performed by five leading international organisations, also shows that the global average surface temperature in 2018 was approximately 1° Celsius above the pre-industrial (1850-1900) baseline.
“The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one,” said WMO Secretary-General Petteri Taalas. “The 20 warmest years on record have been in the past 22 years. The degree of warming during the past four years has been exceptional, both on land and in the ocean.”
“Temperatures are only part of the story. Extreme and high impact weather affected many countries and millions of people, with devastating repercussions for economies and ecosystems in 2018,” he said.
“Many of the extreme weather events are consistent with what we expect from a changing climate. This is a reality we need to face up to. Greenhouse gas emission reduction and climate adaptation measures should be a top global priority,” said Mr. Taalas.
Noting “with concern” this data, which was first released in November 2018, UN Secretary-General Guterres said it confirms “the urgency of addressing climate action”, and echoes the science presented by the Intergovernmental Panel on Climate Change (IPCC) in its October 2018 special report on the impacts of a global warming of 1.5°C.
The IPCC report 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 emissions of carbon dioxide, attributable to human activity, would need to fall by about 45 per cent from 2010 levels by 2030, reaching ‘net zero’ around 2050.
The Secretary-General stated that, “to make these transformations, we need to significantly increase the global level of climate action and ambition.”
Guterres will convene a Climate Summit on 23 September this year with the aim to mobilize political will to raise ambition for the achievement of the goals of the Paris Agreement and it will also demonstrate trans-formative action in all the areas where it is needed.
The Summit will focus on nine key areas — mitigation ambition; energy transition; industry transition; nature-based solutions; infrastructure, cities and local action; climate finance and carbon pricing; resilience and adaptation; social and political drivers; and mobilization.
