The Earth is not flat, yet our visualisations of Earth are frequently from a 2-dimensional perspective. Whether that’s from Google Maps, or the most advanced optical satellites, our data is flat. But, a remote sensing technique using stereo imagery allows us to derive 3D models of landscapes from 2D still images. Stereo Imagery When satellites … More Looking at the Earth in 3D with Stereo Imagery
This week, the IPCC (Intergovernmental Panel on Climate Change) released a landmark report about the implications of a 1.5°C world compared to a 2°C, or warmer, world. The purpose of the report was to show governments, businesses and stakeholders that we need to take urgent action now in order to limit global warming to 1.5°C above … More The Cryosphere at 1.5°C and 2°C
Geologists split periods of Earth’s history into different chunks of time. Early Earth is categorised by the Hadean eon, but as soon as Earth cooled enough for tectonic plates to form, we entered the Archean eon (around 4 billion years ago). 2.5 billion years ago, the Proterozoic eon began, defined by the presence of complex … More Defining Geologic Time
Peatlands are perfect archives of past environmental change. It takes a very long time for peat to accumulate – on the order of 1 mm per year for temperate regions, but as low as 0.1 mm per year in the Arctic. The high water table of wetlands means that organic matter takes much longer to decompose … More Dating Peat
This week I was delighted to join the Quaternary Research Association’s 2018 conference with my fellow Masters by Research accomplice, Vicky Naylor. We had a fantastic time and in this blog post I’ll share some of my highlights from the conference. It’s an exciting time in Quaternary research and this was echoed in the theme … More What’s new in the Quaternary? – QRA 2018 Conference
On January 22nd 2018, the University of Exeter are releasing a brand new course that explores the science, impacts and evidence of climate change. Here are 6 reasons why you should sign-up! 1) Solve the Weather v Climate myths You may have seen this tweet from the President of the United States recently: In the … More 6 reasons to learn about Climate Change with the University of Exeter
Testate Amoebae are single-celled organisms (protists) that form a hard shell around themselves (test) for protection. This means they are incredibly hardy creatures, that can be preserved for thousands of years without any damage. They live on the surface of wetlands, bogs and soils – including peatlands – in incredible abundance. A sample of 5cm³ moss from … More Testate Amoebae – What can they tell us about the past?
