A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene — an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed nanoscale copper wires with specially shaped surfaces to […]

For that reason, monitoring […]

Primary forests are crucial for biodiversity conservation and store high quantities of carbon in biomass, therefore helping to mitigate climate change. Credit: Tzvetan Zlatanov Europe’s primary forests: What to protect? What to restore? Primary forests are forests without any signs of past human use and where ecological processes are not […]

Past and future trends in global mean temperature spanning the last 67 million years. Oxygen isotope values in deep-sea benthic foraminifera from sediment cores are a measure of global temperature and ice volume. Temperature is relative to the 1961-1990 global mean. Data from ice core records of the last 25,000 […]

Claire O’Neill is critical also of former Australian prime minister Tony Abbott’s new trade position GETTY IMAGES The UK’s former climate chief has criticised the Prime Minister over failings in the run-up up to next year’s climate summit, COP26. Claire O’Neill condemns what she calls broken promises and backsliding on […]

This species is abundant in the xeric forest-steppe ecotone, where periodic massive mortality events have been documented in relation to extreme droughts in Patagonia during the 20th century.

Ocean Carbon Uptake Widely Underestimated The world’s oceans soak up much more carbon than most scientific models suggest, according to new research. Previous estimates of the movement of carbon (known as “flux”) between the atmosphere and oceans have not accounted for temperature differences at the water’s surface and a few […]
