The adaptation measures taken in the world do not reduce the risk that climate change poses to humanity7 de November 2021Anna Ramon Revilla
A recent study shows that the measures taken are fragmented, local and not transformative. CREAF calls for more integrated and coordinated measures capable of reducing the risk that climate change poses to people.
More than 4,400 terrestrial and freshwater species are threatened by changes in the fire regime. While many species are at risk by the increased frequency and intensity of fire, its suppression can be harmful to some life forms and ecosystems.
Evolution leads to an increasing number of species, and that's why it is so difficult for us to know how many of them inhabit the Earth. Should we spend efforts to conserve all of them or would it be enough with just a few?
An extensive review of studies and databases reveals that drought and an increase in temperature are already causing species substitutions, greater aridity, higher forest fire risk, lower soil fertility, and lower water availability, among other negative impacts.
Freshwater ecosystems near densely populated areas have levels of phosphorus which are very high and out of balance with nitrogen levels. This has resulted in altered ecosystem functioning, lower water quality, and has made water conservation more difficult.
The worst scenario occurs when NAO and EA are in opposite phases. This ocurred in the first few years of the previous decade and during this period, the CO2 uptake was below average. Recently, NAO and EA were in the same phase and ecosystems have been able to remove more carbon from the atmosphere.
