Climate Change & Anthropocene Extinction 33: ‘Temperate biodiversity’ faces specific challenges

The response of endemic biodiversity to climate change in Earth’s temperate climate zones is complex. A new study suggests that species that have evolved in regions with relatively high natural climate variability may at the same time be more resilient … Continue reading

Climate Change & Anthropocene Extinction 29: Last straw Madagascar bamboo lemur drying out

When you’re looking at the effects of climate change on the forests of Africa, you may be inclined to overlook Madagascar, the continent’s largest island. But especially when biodiversity is your concern, it deserves special attention. In fact Madagascar has … Continue reading

Climate Change & Anthropocene Extinction 24: Insects Germany declined 76% in just 27 years(!)

The numbers of flying insects in nature reserves throughout Germany show a staggering decline. Taken on average over the months of April to October between 1989 and 2016 insect numbers declined 76%. In mid-summer measurements show an even more rapid … Continue reading

Climate Change & Anthropocene Extinction 23: Amazon ‘tipping point’ is a sliding process, from +1C

In this article we try to quantify the Amazon rainforest climate tipping point, based on available scientific literature. We conclude there’s no real basin-wide threshold temperature to activate the forest-killing biome switch. Rather it seems to be a sliding process, … 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 17: These 6 killers still bigger drivers than warming – IUCN study

An analysis of IUCN’s Red List of endangered species places 10 drivers of the Holocene-Anthropocene Mass Extinction in order of severity. It concludes that classical environmental threats like deforestation, hunting and overfishing – in 2016 – still top the list … Continue reading

Climate Change & Anthropocene Extinction 15: On 65% Earth surface biodiversity is beyond safe limit

Again, the use of a geographical approach (and here defining biodiversity as ‘biotic intactness’) shows the Holocene-Anthropocene Mass Extinction is progressing faster then generally thought – and ‘biodiversity safe limits’, however arbitrarily defined, have already been passed on most of … Continue reading

Climate Change & Anthropocene Extinction 14: Vertebrates in general decline, mass extinction underestimated

Whether you focus on mammals, birds, reptiles or amphibians – land vertebrates are in rapid decline everywhere around us, illustrating a general decline of Life on Earth – and a prelude to the Holocene-Anthropocene Mass Extinction, that is being underestimated … Continue reading

Climate Change & Anthropocene Extinction 9: Cascading extinctions speed up biodiversity loss – and warming

Yes, we found yet another publication that is critical of one-dimensional biodiversity loss projections of climate change – and again it is a component of interspecies interaction that may be underestimated. We’ve previously looked at species competition and at evolutionary … Continue reading

Climate Change & Anthropocene Extinction 8: Locally biodiversity might increase, kick-starting (global) decline

As species migrate in response to climate change and do so at different rates and dispersal directions, extra ecosystem disturbances might arise, leading to temporary local biodiversity increases – fuelling a net (global) downward trend.
