Climate Week 2015: Climate Science Challenge

This year we celebrated Climate Week with a public event at Manchester Museum inviting visitors to take part in our Climate Science Challenge. Over 1,200 visitors joined in our celebrations, and together with researchers and students from British Antarctic Survey, Liverpool John Moores University, Manchester Metropolitan University, and the University of Manchester, took part in hands-on activities and experiments, exploring a range of climate change issues.   Taking on the Climate Science Challenge As part of the event, visitors were invited to join in our challenge by speaking to researchers and taking part in their own experiments to find the answers to important climate change...

Interview: Powering the Top of the World

Powering the Top of the World is a new documentary by Christoph Mazur and Chris Emmott, from Imperial College London. It explores energy supply in Nepal, and the innovative solutions to sustainable energy provision in some of the most remote parts of the world. With over 1.2 billion people with no access to electricity across the globe, these issues are echoed in countries the world over. Christoph Mazur speaks to Climatica about their work in Nepal, the moviemaking process, and their night at the BAFTAs.     Tell us about your new film ‘Powering the top of the world’ You’re a researcher first and foremost, what...

Snail shells provide detailed records of environmental change

By Dr Jonathan Lewis and Prof Melanie Leng The shells of molluscs from all over the world – on land, in lakes, and in the ocean – contain very detailed imprints of past climate change. Using isotope analysis, we can extract these signals and start to piece together long-term climate variations. You will never look at a garden snail in the same way again! What are molluscs? Molluscs are soft-bodied (invertebrate) organisms that are widespread in terrestrial, freshwater, and marine habitats. We can split them into two basic groups: Gastropods: Molluscs with up to one shell or ‘valve’ (such as snails or slugs) Bivalves: Molluscs...

In brief: the IPCC Climate Change 2014 Synthesis Report

Ignorance can no longer be used as an excuse for no action Michel Jarraud – World Meteorological Organization    What is the Synthesis Report? The newly published IPCC Synthesis Report, released on 2nd November, draws together the key findings of the three Working Groups of the IPCC (The Physical Science Basis; Impacts, Adaptation, and Vulnerability; Mitigation of Climate Change – available here) as well as two Special Reports. It forms the final, and possibly most important, instalment of the IPCC’s Fifth Assessment Report (AR5).

The greenhouse effect and its role in the Earth’s climate

The Sun bathes the Earth in radiation. Much of this radiation reaches the surface, warming the planet and driving the climate.  The surface then emits heat (as infrared radiation), most of which does not escape to space, but is instead absorbed by gases in the Earth’s atmosphere.  These gases then warm, emitting further heat radiation both to space and back towards the Earth’s surface.  This is what we all know as the greenhouse effect.   The Earth’s energy balance In order for the radiative budget of the Earth to be in equilibrium – that is heat radiation leaving the planet to equal the absorbed solar...
