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

Climate Change & Holocene-Anthropocene Mass Extinction 1: First of all, what are we talking about?

Yes, you’ve guessed it: a new series – and one we think is (even) more important than the previous climate series on Bits of Science, like our short (ongoing) understanding sea level rise series, and the more elaborate series about … Continue reading

Understanding Sea Level Rise, p4: ice sheet dynamics and (13) melting feedbacks – a background to 21st century SLR acceleration

In 2016 two influential new publications raised the possibility of a rapid acceleration of sea level rise in the 21st century – to ±2 metres (DeConto & Pollard) or more (2-5m, Hansen et al). In this background article we take … Continue reading

Understanding Sea Level Rise, p3: it’s about timescales, speed of change & carbon budget – world aims for 29-55m sea level rise

In our previous article of the series we’ve looked at an overview of global sea level rise forecasts for the year 2100 – and seen that these forecasts have a very large spread, and also seem to increase with time … Continue reading

Understanding Sea Level Rise, p2: A short chronology of SLR forecasts for the year 2100 (showing they increase with time)

Sea level rise is a slow process. Other consequences of climate change are generally felt much sooner. But there is something odd about the forecasts. They seem to be catching up with us, bringing a distant future closer to our … 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?
