Scottish project tackles ‘environmental impact’ of pills

A new Scottish health project aims to tackle potential harm caused to the environment by pharmaceuticals. An estimated 100 million treatments are prescribed every year in Scotland. After a pill passes through a person’s body, some of its compounds reach rivers, lochs and the sea because waste water plants cannot filter them out. While the […]

Food ‘made from air’ could compete with soya

Finnish scientists producing a protein “from thin air” say it will compete with soya on price within the decade. The protein is produced from soil bacteria fed on hydrogen split from water by electricity. The researchers say if the electricity comes from solar and wind power, the food can be grown with near-zero greenhouse gas […]

Climate change Oceans running out of oxygen as temperatures rise

Climate change and nutrient pollution are driving the oxygen from our oceans, and threatening many species of fish. That’s the conclusion of the biggest study of its kind, undertaken by conservation group IUCN. While nutrient run-off has been known for decades, researchers say that climate change is making the lack of oxygen worse.  Around 700 […]

Forests facing climate balancing act

Forests can cope with a warming world if – and only if – temperature rises increase in line with increases in atmospheric carbon dioxide. Increased CO2 allows trees to develop physiological characteristics, such as greater foliage, that can cope with higher temperatures. But researchers warn that a break in the temperature-CO2 increase ratio could trigger […]

Climate change ‘Bleak’ outlook as carbon emissions gap grows

Countries will have to increase their carbon-cutting ambitions five fold if the world is to avoid warming by more than 1.5C, the UN says. The annual emissions gap report shows that even if all current promises are met, the world will warm by more than double that amount by 2100. Richer countries have failed to […]

Climate change: Greenhouse gas concentrations again break records

Atmospheric concentrations of carbon dioxide and other greenhouse gases once again reached new highs in 2018. The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.  Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.  Since 1990 […]

Coal the beginning of the end

The fuel that powered the industrial revolution may be in decline at last. This year looks set to see the largest fall in electricity production from coal on record, according to a new report. The reduction is estimated to be more than the power generated from coal in Germany, Spain and the UK combined.  It […]
