Rocks can restore our climate… after 300,000 years

A study of a global warming event that happened 93 million years ago suggests that the Earth can recover from high carbon dioxide emissions faster than thought, but that this process takes around 300,000 years after emissions decline. Scientists from Oxford University studied rocks from locations including Beachy Head, near Eastbourne, and South Ferriby, North […]

Bigger storms ahead

For the past 40 years – as far back as satellite records show – the frequency and intensity of tropical cyclones has remained relatively stable – about 90 of these storms spin through the world each year, and over the decades, cyclones’ average intensity and maximum wind speed have also remained consistent. These storms may […]

Iron from melting ice sheets may help buffer global warming

A newly-discovered source of oceanic bio-available iron could have a major impact on our understanding of marine food chains and global warming. A UK team, including researchers from the University of Bristol, has found that summer melt-waters from ice sheets are rich in iron, which will have important implications on phytoplankton growth. Their findings are […]

Climate disputes have little effect on the public, says study

Researchers have tracked how media coverage can affect levels of public interest in climate science by comparing volumes of searches for climate change issues on Google’s search engine. They analysed data available on Google Trends between 2004 and 2013, looking in particular at the period around ‘climategate’ and the discovery of an error in the […]

Reducing emissions will be the primary way to fight climate change: study news

Forget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth’s atmosphere or seeding clouds to reduce the amount of light entering earth’s atmosphere. Those approaches to climate engineering aren’t likely to be effective or practical in slowing global warming. A new report by professors from University of […]

Modern humans born from climate change: study

Early human evolution was driven by short pulses of rapid environmental change in East Africa, according to new research from academics at UCL and The University of Manchester. The study, which is published in the journal PLoS ONE, has shown for the first time the link between the waxing and waning of huge lakes in […]

Global warming: govt to set up National Institute of Himalayan Glaciology

In a move that is being seen as a significant snub to IPCC and its chief Dr R K Pachauri, the government has announced it would set up a new body to monitor the effects of global warming as it could not rely on the UN’s Intergovernmental Panel on Climate Change (IPCC). The IPCC and […]

Carbon capture and storage likely to cause earthquakes

Carbon capture and storage, or CCS, is a major component of the world’s greenhouse gas reduction strategy. Involving injecting and storing carbon dioxidein underground geologic reservoirs, the method is used at several oil and gas exploration sites worldwide to prevent the gases from entering the atmosphere. But to significantly reduce emissions, CCS would need to […]

Deforestation of sandy soils a greater threat to climate change

Deforestation may have far greater consequences for climate change in some soils than in others, according to new research led by Yale University scientists – a finding that could provide critical insights into which ecosystems must be managed with extra care because they are vulnerable to biodiversity loss and which ecosystems are more resilient to […]

Multiple metrics of climate change reveal unappreciated impacts on biodiversity

Scientists use climate change metrics, such as changes in seasonality or the emergence of new climates, to predict how climate change will impact biodiversity levels. These climate change metrics are typically studied in isolation, so it is difficult to accurately predict how changes in climate might impact levels of biodiversity. For the very first time, […]
