<div style="text-align: justify; "><b style="font-size: 1rem;">The past eight years were the hottest since records began, the United Nations confirmed Thursday, despite the cooling influence of a drawn-out La Nina weather pattern.</b><br></div><div style="text-align: justify; "><br></div><div style="text-align: justify;">Last year, as the world faced a cascade of unprecedented natural disasters made more likely and deadly by climate change, the average global temperature was about 1.15 degrees Celsius above pre-industrial levels, the World Meteorological Organization said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The US National Oceanic and Atmospheric Administration and NASA released similar 2022 global temperature figures on Thursday and Bill Nelson, head of the US space agency, described them as "alarming."</div><div style="text-align: justify;">"Forest fires are intensifying, hurricanes are getting stronger, droughts are wreaking havoc, sea levels are rising," Nelson said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"Extreme weather patterns threaten our well-being across this planet," he said. "And we need some bold action."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The WMO, a UN agency, said the past eight years "were the warmest on record globally, fuelled by ever-rising greenhouse gas concentrations and accumulated heat."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The hottest year on record was 2016, followed by 2019 and 2020, it found.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Last year marked the eighth consecutive year that annual global temperatures were at least one degree over the pre-industrial levels seen between 1850 and 1900.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The Paris Agreement, agreed by nearly all the world's nations in 2015, called for capping global warming at 1.5C, which scientists say would limit climate impacts to manageable levels.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">But the WMO warned Thursday that "the likelihood of -- temporarily -- breaching the 1.5C limit... is increasing with time."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Russell Vose, NOAA's chief of climate monitoring, said there is a 50-50 chance that there will be a year in the 2020s above 1.5C, although a sustained average of 1.5C warming is not projected to occur until the late 2030s or 2040s.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The WMO reached its conclusions by consolidating six leading international datasets, including those of NOAA and the European Union's Copernicus climate monitor (C3S).</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">- La Nina effect 'short-lived' -</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The UN agency highlighted that the warmest eight years on record had all been since 2015, despite consecutive La Nina events since 2020.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The weather phenomenon has a cooling effect on global temperatures.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Last year was therefore "just" the fifth or sixth hottest year ever recorded, the WMO said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The situation last year was more extreme in some places.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Copernicus said in its annual report Tuesday that the planet's polar regions experienced record temperatures last year, as did large swathes of the Middle East, China, central Asia and northern Africa.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Europe endured its second-hottest year ever as France, Britain, Spain and Italy set new average temperature records and heatwaves across the continent were compounded by severe drought conditions, it said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">For the planet as a whole, the WMO said the impact of La Nina, which is expected to end within months, would be "short-lived."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The weather pattern, it said, "will not reverse the long-term warming trend caused by record levels of heat-trapping greenhouse gases in our atmosphere."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">- Extreme weather events -</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The WMO said the trend was clear.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"Since the 1980s, each decade has been warmer than the previous one," it said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The average temperature for the period 2013-2022 was 1.14C above the pre-industrial baseline.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">It stood at 1.09C between 2011 and 2020, according to estimates by the UN's climate science advisory panel, the IPCC.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">This, WMO said, "indicates that long-term warming continues," with the world "already approaching the lower limit of temperature increase the Paris Agreement seeks to avert."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Like NASA's Nelson, the WMO chief Petteri Taalas highlighted extreme weather events in 2020, pointing to floods that submerged a third of Pakistan, record-breaking heatwaves in China, Europe and the Americas, and a drawn-out drought in the Horn of Africa.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">At the COP27 climate summit in November, UN chief Antonio Guterres unveiled a five-year, $3-billion plan to build a global early warning system for deadly and costly extreme weather events amplified by climate change.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">So far, only half of the 193 UN member states have such systems, Taalas said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, said collective action is needed now but "it's never going to be too late to make better decisions.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"Future warming is a function of future emissions of carbon dioxide," Schmidt said. "At any point in the future, we can decide to do something that will reduce the emissions and reduce the temperatures in the future."
