Climate Change & Anthropocene Extinction 20: Amazon tree transpiration crucial to keep rainforest wet

The individual trees in the Amazon rainforest play a crucial role in keeping the rainforest intact. Not just because the trees together create the forest, but also because – together – they create the climate (through something called the shallow … Continue reading

Climate Change & Anthropocene Extinction 19: Earth has 60,065 tree species, almost half threatened

When we think of the Holocene-Anthropocene Mass Extinction we may think of coral reefs, birds, amphibians and iconic mammal species – essentially following the IUCN Red List. But it really is time we started to take a closer look at … Continue reading

Climate Change & Anthropocene Extinction 16: Land use & warming exert same stress on tropical biodiversity

Anthropogenic climate change and land use change in the form of agricultural expansion (‘habitat conversion’ – a sweet description for deforestation) act as synergistic drivers of biodiversity loss – in a Costa Rican environmental experiment – literally drying out the … Continue reading

This is what carbon climate feedbacks look like! Atmospheric monitoring shows dramatic 2015 CO2 emissions record unfolding

Welcome to the future. 2015: The hottest year on record. With a likely coral bleaching record. And sadly also the year with a likely extreme CO2 emissions record. Because, using satellites, we can see the very positive carbon climate feedbacks … Continue reading

World food demand could double by 2050 – if so agricultural intensification could save 2 billion tonnes of CO2 per year

A new projection by the University of Minnesota and the University of California Santa Barbara shows global food demand could rise by 100-110 percent between 2005 and 2050, which would pose a grave threat to remaining tropical rainforests and would … Continue reading

Study shows binary switches between forest, savanna, desert: macro-scale climate-biodiversity tipping points

Researchers of Wageningen University find in South America, Africa and Australia under climatic change forest, savanna and treeless systems don’t gradually phase across, but rather tip over.

Tropical forest CO2 fertilisation: self-mitigation of emissions possibly around 15 percent

In which case increased tropical forest density would sort of average out emissions of tropical deforestation. [Is it just us or do you share the feeling something is uncomfortably unsustainable about that comparison?] A couple of days ago we reported … Continue reading

The forest fire feedback, Yellowstone’s case: ecosystem shift by 2050

Climate change could cause the forests of the world’s oldest national park, Yellowstone, in the Eastern Rocky Mountains, to shift to a gras and shrub ecosystem, US scientists warn. It could happen in four decades, and will likely not be … Continue reading
