Books: Hot Air: Climate denial and scientific discoveries ’emerged simultaneously’

Denial of climate science emerged simultaneously with key scientific discoveries about humanity’s impact on our planet, according to a new book. Professor Peter Stott – author ofHot Air: The Inside Story of the Battle Against Climate Change Denial – began 25 years ago in the then-obscure field of the detection and attribution of climate change. As […]

‘Tipping points’ in Earth’s system triggered rapid climate change 55 million years ago, research shows

A team of researchers, led by Dr Sev Kender from the University of Exeter, have made a pivotal breakthrough in the cause behind the Paleocene-Eocene Thermal Maximum (PETM) – an extreme global warming event that lasted for around 150 thousand years which saw significant temperature rises.   Although previous studies have suggested volcanic activity contributed to […]

Study pinpoints key causes of ocean circulation change

Researchers have identified the key factors that influence a vital pattern of ocean currents. The Atlantic meridional overturning circulation (AMOC) carries warm water from the tropics northward. Many scientists think that this heat transport makes areas including north-west Europe and the UK warmer than they would otherwise be. Climate models suggest the AMOC is likely to […]

“Stark warning”: Combating ecosystem collapse from the tropics to the Antarctic

February 26, 2021 – Eminent scientists warn that key ecosystems around Australia and Antarctica are collapsing, and propose a three-step framework to combat irreversible global damage. Their report, authored by 38 Australian, UK and US scientists from universities and government agencies, is published today in the international journal Global Change Biology.  Researchers say it heralds a […]

Using human rights laws may be most effective way of harnessing international legislation to protect the Amazon, study shows

February 22, 2021 – Using laws governing human rights may be the best way of harnessing international legislation and tribunals to protect the Amazon, a new study shows. Safeguarding the rainforest is a critical priority because of the ecosystem’s planetary importance. Recent increases in deforestation and fires in the region have made this even more […]

Plant evolves to become less visible to humans

November 24, 2020 – A plant used in traditional Chinese medicine has evolved to become less visible to humans, new research shows. Scientists found that Fritillaria delavayi plants, which live on rocky slopes of China’s Hengduan mountains, match their backgrounds most closely in areas where they are heavily harvested. This suggests humans are “driving” evolution of this […]

Hundreds of sharks and rays tangled in plastic

July 8, 2019 – Hundreds of sharks and rays have become tangled in plastic waste in the world’s oceans, new research shows. University of Exeter scientists scoured existing published studies and Twitter for shark and ray entanglements, and found reports of more than 1,000 entangled individuals. And they say the true number is likely to […]

Experiencing extreme weather is not enough to convince climate change sceptics in the U.S.

Oct. 2, 2018 – Experiencing extreme weather is not enough to convince climate change skeptics that humans are damaging the environment, a new study shows. Political bias and partisan news reporting influence whether people report experiencing certain extreme weather events, the research suggests. But Americans who lived in areas where a variety of extreme events […]

Climate-threatened animals unable to relocate

May 17, 2018 – Many of the European mammals whose habitat is being destroyed by climate change are not able to find new places to live elsewhere. 30 of the 62 mammal species in the University of Exeter study will have their habitat substantially affected by climate change, but don’t have the traits that could […]

Sea temperature changes contributing to droughts

July 19, 2017 – Fluctuations in sea surface temperature are a factor in causing persistent droughts in North America and around the Mediterranean, new research suggests. A team from the universities of Exeter, Montpellier and Wageningen analysed data from 1957–2002 and found sea surface temperatures in the North Pacific and North Atlantic became increasingly variable, […]
