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 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 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 4: Earth’s biodiversity may include >1,000,000,000,000 species(!)

Yes. That’s ONE TRILLION. ‘Possibly’ – as recent research using statistical scaling rules shows Earth’s total biodiversity, expressed in numbers of species, lies somewhere between 100 billion and (possibly more than) ten times as much. Welcome to the world of … Continue reading

Climate Change & Holocene-Anthropocene Mass Extinction 3: Biodiversity is function of time and plate tectonics

Here’s just a quick supplement on yesterday’s article, showing Earth’s historical biodiversity graph correlates with different phases of plate tectonics.

Climate Change & Holocene-Anthropocene Mass Extinction 2: Biodiversity graph shows Garden of Eden is Now

Yesterday we tried to place the Holocene-Anthropocene Mass Extinction in the context of Earth’s past mass extinctions. Listing the Holocene Extinction as the ‘Sixth Mass Extinction’ proves problematic for various reasons. Today we offer additional context: although a mass extinction … Continue reading

Understanding Sea Level Rise, part 1: Thermal Expansion – a Physical Foundation of several metres, irrespective of ice melting

In between our series about the global temperature trend and our (upcoming) series about climate & biodiversity, let’s do a short series about sea level rise, shall we?

The Syrian drought of 2006-2010 fits in climate trend of lower precipitation and higher temperatures, this graph shows

Over 2006 to 2010 a prolonged drought, unprecedented in modern documented history, caused a farming collapse in Northeastern Syria. Winter rainfall in the otherwise green & productive ‘Fertile Crescent’ decreased by at least a third in Syria (and up to … Continue reading

Permian-Triassic climate lesson: Don’t even try to adapt to a mass extinction, mitigate – a single plague can kill a planet!

The second part of the new IPCC report, about the impacts of climate change, has been released on Monday. Across the globe dutiful journalists filled the headlines of their newspapers – and as they presume most of their readers are … Continue reading

’2 degrees climate target fails because politicians cannot handle a margin of scientific uncertainty’

The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research from the University of Gothenburg and Columbia … Continue reading
