A warmer Arctic fuels Siberian wildfires

,
Global warming, says a Chinese study, promotes wildfires which, in turn, reduce the frequency of rainfall leading to a vicious cycle
Climate change and increasing pressure from human activities generate an increased release of metals from coasts to oceans. Pickpik Royalty-Free photo

Climate change enhances metal release in coastal areas

,
Events such as rising sea levels, increasing temperatures and changes in precipitation affect metal sequestration conditions in underground estuaries, explains a Swedish study

‘Stop land degradation or we will face health risks,’ say activists ahead of COP29

,
Land degradation poses a global threat to human health, activists recall as the UN Climate Convention in Baku approaches. In the US, 95 per cent of land at risk
Pollution by heavy metals, pesticides, microplastics and nanoplastics causes cardiovascular damage by interacting with protein-bound thiols, inducing oxidative stress and inflammation and altering circadian rhythms.

Soil pollution causes the spread of cardiovascular diseases

,
Contamination of soil, water and air causes around 9 million premature deaths per year, a German study says. More than half are of cardiovascular origin

For soil invertebrates, pollution is a worse threat than climate

,
A meta-analysis of more than 600 studies shows that pollution is the most critical factor for the conservation of soil invertebrate biodiversity

Sea level rises threatening wetland carbon

,
L'ascesa del livello del mare mette a rischio la capacità di stoccaggio del carbonio alterando la presenza dei microbi e la vegetazione, osservano i ricercatori americani

Heat and drought drive carbon loss in tropical forests

,
A warmer and drier climate will impact the carbon balance of forests in the future, says a US study. The phenomenon will accelerate the loss of the oldest element and reduce the supply of the new one

Soil bacteria survive by cooperating with each other

,
With gene sequencing, researchers at Ohio State University have shown how bacteria cooperate to thrive in environments characterised by different pH levels
In California the rate of erosion after post-fire floods increased between 3.5 and 4.6 times. Photo: Tomwsulcer CC0 1.0 Universal CC0 1.0 DeedTomwsulcer CC0 1.0 Universal CC0 1.0 Deed

In California, fires and subsequent floods accelerate erosion

,
According to a study by the US Geological Survey, erosion on California coasts is closely linked to extreme weather events enhanced by progressive climate change
