- Top nature and climate stories: Humans could use 60% more natural resources by 2060; US 'warming hole' cooled by reforestation; Study reveals how the ocean's largest whales produce their songs.
1. US 'warming hole' cooled by reforestation, study shows
A vast area of reforested land across the Eastern US is producing a "warming hole" where temperatures have stabilized or cooled rather than warmed, according to new research.
While the intensifying climate crisis continues to break temperature records around the world, reforestation conducted during the last century in many southeastern US states has helped stall its warming effects. The reforestation programmes were conducted to replace tree cover destroyed by early settlers.
Trees draw water through roots to the leaves in a process known as transpiration, which is then released as vapour that helps cool the surrounding atmosphere.
“The reforestation has been remarkable and we have shown this has translated into the surrounding air temperature,” study lead Mallory Barnes of Indiana University environment told The Guardian.
“The ‘warming hole’ has been a real mystery and while this doesn’t explain all of it, this research shows there is a really important link to the trees coming back,” she said.
2. Humans could use 60% more natural resources by 2060, says UN
Humans consumption of the planet's natural resources is set to see a 60% increase by 2060, according to the United Nations Environment Programme's flagship Global Resources Outlook report 2024.
Urbanization, industrialization and runaway population growth are increasing resource intensity for sectors like food, mobility, housing and energy.
The UN estimates the global population will expand from around 8 billion currently to 9.7 billion by 2050, reaching nearly 10.4 billion by 2080. This would put an unprecedented strain on the Earth's natural resources.
As the chart shows, the total amount of raw materials extracted to meet final consumption demand (material footprint) has been increasing over time, consistent with population growth and output.
The report outlines the need to switch to more sustainable and responsible resource use to avoid exhausting the planet's finite resources, in line with the UN Sustainable Development Goals.
