Climate Change & Anthropocene Extinction 43: Expert explains biodiversity graph Royal Society report

It’s the end of the year so a good time to evaluate where we’re standing. Our climate-biodiversity series has progressed to episode 43. If you’ve missed it, we highly recommend you start at part 1, preferably under a Christmas tree … Continue reading

Climate Change & Anthropocene Extinction 35: 9 megatrend graphs show little base for optimism

Over 15,000 scientists have endorsed a newly published paper titled ‘World Scientists’ Warning to Humanity: A Second Notice’ that’s set to quickly become a landmark publication. Essentially it’s an overview update (and very digestible, just a thousand words) on the … Continue reading

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 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 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 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

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 11: New climate-biodiversity models better; now need more data

Predictive models that can forecast biodiversity decline under anthropogenic climate change used to be too simplistic, as these ignored crucial biological mechanisms such as demography, dispersal, evolution, and species interactions (for instance species competition and ecosystem dependence). Fortunately these climate-biodiversity … Continue reading

Climate Change & Anthropocene Extinction 10: Biodiversity loss accelerates under warming, metastudy shows

Climate change leads to species extinctions and exponentially so: the loss of biodiversity is set to accelerate under continuation of global average temperature rise.

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
