From the green-fanged tube web spider with a nasty bite to the Asian box tree caterpillar that destroys hedges, Britain’s wildlife is looking a little more exotic in places. Climate change has caused dozens of species to colonise new parts of the country in the past decade, a study has found.

Dr Joeri Rogelj is a lecturer in climate change and the environment at the Grantham Institute at Imperial College London, and Prof Piers Forster is professor of climate physics at the University of Leeds and founding director of the Priestley International Centre for Climate.
The concept of a “carbon budget” has proved to be both elegantly simple and stubbornly complicated. The theory dictates that the total amount of CO2 emitted until emissions are taken down to zero determines the maximum warming that the world will subsequently experience. This was the promise from a series of seminal studies published nearly a decade ago. Our latest understanding of climate science teaches us that this promise is still largely kept, but it turns out things are not quite so straightforward when estimating how much carbon budget remains if we want to cap warming to a precise level. The estimated size of the remaining carbon budget can depend on a whole range of factors, which makes it much trickier to compare different estimates directly. As the Paris Agreement has the goal to keep warming well-below 2C and preferably 1.5C, the trillion-dollar question thus became: How much of a carbon budget do we have left? This is an important question. Knowing how much remaining carbon budget is left allows us to define mitigation pathways towards achieving the Paris temperature goal. It also allows scientists to inform the adequacy of global net-zero goals.
