Pollinators: first global risk index for species declines and effects on humanity

Disappearing habitats and use of pesticides are driving the loss of pollinator species around the world, posing a threat to “ecosystem services” that provide food and wellbeing to many millions – particularly in the Global South – as well as billions of dollars in crop productivity. This is according to an international panel of experts, […]

Climate change will transform cooling effects of volcanic eruptions

Researchers have shown that human-caused climate change will have important consequences for how volcanic gases interact with the atmosphere. The researchers, from the University of Cambridge and the UK Met Office, say that large-magnitude eruptions will have greater effects as the climate continues to warm. However, the cooling effects of small- and medium-sized eruptions could […]

Earth’s interior is swallowing up more carbon than thought

Scientists from Cambridge University and NTU Singapore have found that slow-motion collisions of tectonic plates drag more carbon into Earth’s interior than previously thought. We currently have a relatively good understanding of the surface reservoirs of carbon and the fluxes between them, but know much less about Earth’s interior carbon stores, which cycle carbon over […]

Climate changed the size of our bodies and, to some extent, our brains

An interdisciplinary team of researchers, led by the Universities of Cambridge and Tübingen, has gathered measurements of body and brain size for over 300 fossils from the genus Homo found across the globe. By combining this data with a reconstruction of the world’s regional climates over the last million years, they have pinpointed the specific […]

Climate Changed the Size of Our Bodies – And Our Brains

The average body size of humans has fluctuated significantly over the last million years and is strongly linked to temperature. Colder, harsher climates drove the… The post Climate Changed the Size of Our Bodies – And Our Brains appeared first on SciTechDaily.
