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 34: ‘Sahel greening’ unlikely to benefit African biodiversity

The below graph comes from a new global temperature trend study that compares different established datasets for land and ocean temperature. The results emphasize an often-overlooked phenomenon: geographically ‘skewed warming’ – leading to planet-wide precipitation shifts. Possible effects not only … 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 31: ‘New’ great ape species – directly at risk of extinction

Say hello to Pongo tapanuliensis, or ‘the Tapanuli orangutan’ – a close relative of yourself who had been hiding in plane sight on the Indonesian island of Sumatra. Sadly, unless hunting and deforestation are halted, you can also immediately say … 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 25: Congo rainforest shows drying trend – and degradation

The climate over the Congolese rainforests (in the central tropics of Africa) seems to show a drying trend over the last four decades. And although this deviation is smaller than multi-annual variation, the average decline in precipitation does lead to … 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 22: Central American rainforests may also dry out – and die

In our previous article we saw how climate change dries out the Amazon rainforest from the South – killing all remaining rainforest in Bolivia and Paraguay, and most in Peru and Brazil. So, we wonder, what’s going on with the … Continue reading

Climate Change & Anthropocene Extinction 21: Amazon rainforest die-off starts in the South, models show

People who follow climate science will likely be well aware that the Amazon rainforest is particularly vulnerable to anthropogenic climate change – as the basin becomes increasingly prone to droughts under rising global temperatures. Much of the Amazon ecosystem, the … Continue reading
