How databases anticipate the impact of climate on ecosystems

,
Despite incomplete data, some models can effectively predict the impact of climate on biodiversity and the spread of plant species in a natural area
In acidic soils such as red clay soils, the use of rock dust for CO2 capture produces disappointing results.

Rock dust helps capture CO2 but not in acidic soils

,
The dispersion of rock dust in the soil is generally an effective way of storing carbon. But in acidic soils, according to an Australian study, this mechanism does not work

Desertification halves soil functionality in Brazil

,
The calculation is contained in research conducted by two universities in the country, which analysed degraded areas in the north-east of Brazil. A confirmation of the impact of desertification on the soil's ability to sequester carbon

Climate change may decrease methane sequestration in the Amazon by 70%

,
A study reveals how methane uptake by forest soil in the Amazon decreases sharply under hot and dry conditions. While production of the same gas increases following heavy rains

Only one-third of water bodies in Europe is in good condition

,
According to the latest report of the EU Environment Agency, the use of pesticides in agriculture continues to impact water quality in Europe. That's why we need to improve the management of aquatic ecosystems to increase resilience

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
