After many years of failed attempts, world leaders have finally signed a comprehensive deal to address climate change at COP21 in Paris. WUN was there.
As the world’s population continues to grow and the effects of global warming and climate change begin to affect crop yields, new and existing crops must be developed that are resilient to temperature extremes, drought and salinity, while also being cheap to produce. The UN Secretary-General, Ban Ki-Moon, himself, noted the scale of the problem saying “diversification of crops with legumes and other practical measures must be scaled up to end hunger while meeting the challenge of climate change”.
Scientists and world leaders are convening in Paris to tackle climate change, and the University of Leeds is well represented at the talks, offering a wealth of expertise in climate change science. Students and alumni of the University of Leeds have also created a short documentary film about the path to Paris and why this COP should be different to previous years, which failed to reach an agreement on how to address climate change. The film, called Atmosphere, is directed by postgraduate student Nick Roxburgh from the University’s School of Earth and Environment and is the result of a successful crowd-funding campaign.
Earth’s early history is likely to have been much less severe than previously thought, according to a study led by the University of Leeds. Asteroid impacts and long-lasting volcanic eruptions called continental flood basalts – the two most commonly cited possible causes of mass extinction events – would have propelled gas and dust into the atmosphere and altered climate for years. But, until now, the impact of years of sulphur dioxide emissions from continental flood basalts was unknown. In a study published online on 23 November in Nature Geoscience, researchers have provided for the first time a quantitative estimate of the degree and nature of the effects that such eruptions had on the Earth’s climate, vegetation and oceans.
A new Government-backed code has been launched that could slash UK carbon dioxide emissions by 220 million tonnes and protect rare wildlife by restoring moors, bogs and mires. The Peatland Code is unveiled at the World Forum for Natural Capital in Edinburgh on 23 November following a successful two-year trial, which has seen businesses fund peatland restoration projects in southwest England, the Lake District and Wales. The Code is based on research by academics at the University of Leeds and Birmingham City University, which revealed that sustainable business investment could reverse the degradation of peatlands and significantly cut greenhouse gas emissions.
More than half of all tree species in the world’s most diverse forest – the Amazon – may be globally threatened, according to a new study. But the study, published on Friday 20 November, in the journal Science Advances, also suggests that Amazonian parks, reserves and indigenous territories will protect most of the threatened species, if properly managed. The findings were announced by a research team comprising 158 researchers from 21 countries, led by Dr Hans ter Steege of Naturalis Biodiversity Center in the Netherlands and Dr Nigel Pitman of the Field Museum in Chicago, USA. The pan-Amazon RAINFOR network led by the University of Leeds contributed hundreds of forest monitoring plots to the effort
The world will gather in Paris in early December for the 21st Conference of Parties (COP21) to develop solutions to climate change and WUN will join them as an official observer organisation.
A new report jointly written by University of Leeds experts reveals that the 6.8 million people who provide unpaid care for loved ones in the UK save the state £132 billion a year. The report for the charity Carers UK, Valuing Carers 2015 – the rising value of carers’ support, is the third in a series looking at the value of carers’ support to the UK economy. It shows a staggering increase in the value of carers’ support since 2001, almost doubling from £68 billion to £132 billion. Researchers attribute this rise to a dramatic increase in the number of hours people are caring for, combined with an increase in the cost of replacement care.
