Multiple
agencies concurred this week that 2022 was among the hottest years on record—a
continuation of a dangerous trend that experts say underscores the need to move
rapidly away from fossil fuels, the primary source of planet-heating pollution.
The
World Meteorological Organization confirmed Thursday
that last year was one of the hottest since record-keeping began. Citing its
analysis of six international datasets, the WMO said that the average global
temperature in 2022 was roughly 1.15°C above preindustrial (1850-1900) levels.
"The
persistence of a cooling La Niña event" prevented 2022 from being even
hotter, but "this cooling impact will be short-lived and will not reverse
the long-term warming trend caused by record levels of heat-trapping greenhouse
gases in our atmosphere," said the United Nations weather agency.
According to the U.S. government's National Aeronautics
and Space Administration (NASA), last year was the fifth-warmest on record,
while the National Oceanic and Atmospheric Administration (NOAA) labeled it the
sixth-warmest.
More
important than ranks, scientists say, is the fact that the
past eight years were the hottest ever. As the WMO explained, "2022 is the
eighth consecutive year (2015-2022) that annual global temperatures have
reached at least 1°C above preindustrial levels."
Furthermore,
each of the past four decades has been hotter than the one preceding it.
"The 10-year average temperature for the period 2013-2022 is 1.14 [1.02 to
1.27]°C above the 1850-1900 preindustrial baseline," the WMO noted.
"This compares with 1.09°C from 2011 to 2020, as estimated by the
Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment report."
Rachel
Licker, a principal climate scientist with the Climate & Energy Program at
the Union of Concerned Scientists, said in a statement
that "these latest data are in line with long-term global warming trends
that will continue to worsen unless heat-trapping emissions are slashed
drastically—far more than what the United States and other major emitters are
currently doing."
"People
in the United States and around the world experienced heart-breaking
devastation from the climate crisis over the last year as a result of
record-breaking heatwaves, drought, storms, and wildfires," said Licker.
"Should
U.S. and global policymakers fail to significantly ratchet up the ambition of
existing climate policies they will all but guarantee irreversible tipping
points will be exceeded," Licker continued. "In addition, more needs
to be done to ensure people, economies, and ecosystems on the frontlines of the
climate crisis receive adequate investments to shore up their resilience."
Roughly
1.1°C of warming to date relative to the late 1800s has already unleashed
increasingly frequent and intense extreme weather disasters across the globe.
Ahead
of last November's COP27 climate summit—which ended, like the 26
meetings before it, with no concrete plan to rapidly move away from
planet-wrecking fossil fuels—the U.N. warned that existing
emissions reductions targets and policies are so inadequate that there is
"no credible path" currently in place to achieve the Paris
agreement's goal of limiting global warming to 1.5°C, beyond which impacts will
grow increasingly deadly, particularly for the poorest members of humanity who
bear the least responsibility for the climate crisis.
The
U.N. made clear that only
"urgent system-wide transformation" can prevent cataclysmic
temperature rise of up to 2.9°C by 2100, but oil and gas corporations—bolstered by
trillions of dollars in annual public subsidies—are still planning to expand
fossil fuel production in the coming years, prioritizing profits over the lives
of those who will be harmed by the ensuing climate chaos.
"Instead
of caving to fossil fuel industry interests aimed at growing their profits, we
need strong leaders willing to implement bold climate policies for the
betterment of people and the planet," Licker said.
"Policymakers
reluctant to move beyond incrementalism and companies engaging in greenwashing
are—quite frankly—stealing the future that rightfully belongs to our
children," she added. "The science is clear: Large-scale,
transformative action is the only path forward."
Licker's
message was echoed by Cherelle Blazer, senior director of the Sierra Club's
International Climate and Policy Campaign.
"Again
and again, the world's foremost scientists and experts are telling us that our
planet is warming at an unprecedented rate and that the threat to our communities,
homes, and lives will worsen without immediate action," said Blazer.
"Yearslong droughts, deadly heatwaves, historic floods, superstorms,
increased food insecurity, and record displacement are the daily reality for
billions of people around the world."
"We have the tools and the scientific evidence we need to halt climate catastrophe, yet all too often we're still seeing business continuing as usual," Blazer added. "We are at a point in the climate crisis where we must do the hard but necessary work to secure a livable planet for all. Anything less is risking the lives and livelihoods of billions of people around the world."
