UN: Wildfires and rising temperatures threaten forests in the northern hemisphere

A new U.N. study said that record wildfires in combination with rising temperatures could turn vital carbon sinks like forests into carbon emitters.

According to a report released by the U.N. Economic Commission for Europe ahead of the COP30 Climate Conference in Brazil, forests in Europe, North America and Central Asia have slowed their ability absorb carbon dioxide.

It warned that if current trends continue these forests may reach a tipping-point where they start releasing more CO2 than they can absorb.

The Paris Agreement targets a reduction of CO2 emissions in order to limit global warming to 1.5 degrees Celsius. These forests offset a large portion of the human-produced emissions of CO2 from fossil fuels, and deforestation.

About half of the carbon stored in the world is found in forests located in the northern hemisphere.

ARCTIC BOREAL WOODS VULNERABLE

In a press release, UNECE Executive Secretary Tatiana Molcean stated that "the message is clear": what we have achieved in the past three decades now faces serious risks from the climate crisis.

The report highlights the vulnerability and large amount of carbon stored in the Arctic boreal forest, which contains nearly half the world's old-growth, primary woodland. The forests are under threat from wildfires and rising temperatures.

According to the report, the northern hemisphere is home to nearly half of the world's primary woodland and over 42 percent of the forest. However, it is becoming increasingly vulnerable to pests, fires, and drought.

A study by the Joint Research Centre of the European Union found that forests in Europe will absorb nearly a third less CO2 per year between 2020-22 and 2010-14.

Molcean stated, "We can't afford to lose our planet's strongest natural defense." The rising tide of fires and drought is pushing the forests to a critical point.

The Brazilian government is launching the Tropical Forests Forever Fund at COP30 to help countries who commit to preserving forests. (Reporting and editing by Mark Heinrich; Additional reporting by Ali Withers, Olivia Le Poidevin).
