“75% of Earth’s ice-free land is directly altered as a result of human activity, with nearly 90% of terrestrial net primary production and 80% of global tree cover under direct human influence.”
“A blueprint for sustainable and integrated farming and crofting activity in the hills and uplands of Scotland”
“Agricultural support payments should be targeting agricultural activity aimed at food production, and should therefore not be accessible for alternative land uses or towards the production of crops not intended for the food chain.”
Burkina Faso, in West Africa, has been fighting with desertification and climate change, and has seen a progressive degradation of its forested landscapes due to the expansion of agriculture.
“Our study shows that Greenland is much more sensitive to natural climate warming than we used to think–and we already know that humanity’s out-of-control warming of the planet hugely exceeds the natural rate,” says Andrew Christ.
” it’s a really important ecosystem to study, especially given how little research takes place in Africa compared to other tropical locales.””
“Combined with the highly precise growth-ring dating, the climatic changes over the 1700 year lifetime of the kauri tree can be linked to other records of environmental change. “
Researchers from the Chinese Academy of Sciences and Cardiff University followed tagged 56 Arctic peregrine falcons and tracked their journeys by satellite.
“In the course of analysing deep-sea cores from the floors of the Arctic Ocean and the northernmost part of the North Atlantic, Walter Geibert and colleagues at the Alfred Wegener Institute in Bremerhaven, and the University of Bremen, Germany revealed a series of sediment layers that were devoid of excess 230Th. “
Rising temperatures could reduce the efficiency of food chains and threaten the survival of larger animals, new research shows.
“Getting an idea of natural climate change through the 11.65 thousand years since the end of the last period of extensive glaciation depends on a variety of indirect measurements or proxies for temperature. “
