The Hidden Environmental Danger in Your Old Fridge

Old fridges, like the author's mother's 30-year-old 'beer fridge', often contain hydrofluorocarbons (HFCs), potent greenhouse gases that contribute to global warming. While CFCs were phased out due to ozone depletion, HFCs, though not ozone-depleting, are now being phased down internationally. Proper disposal is crucial, but options vary across Australia, with some states banning e-waste from landfills and others offering buyback schemes.

Natural forest restoration hailed as best climate solution

A scientist argues that natural forest restoration is the "best" climate change solution, not just for carbon drawdown but for improving human livelihoods. Unlike technological fixes with trade-offs, nature-based solutions harness feedback loops for sustainable recovery, benefiting both the environment and local communities.

No escape from the heat: Why scientists are sweating over warmer nights

Nights are warming faster than days globally, impacting crops, ecosystems, and human health. Cities trap heat due to concrete and lack of green cover, while rising greenhouse gases act like a thicker blanket, preventing heat escape. This 'asymmetric warming' alarms scientists, indicating a fundamental shift in the planet's ability to cool itself.

How LNG interests are seeking to disrupt global talks on decarbonising shipping

Observers say pressure on IMO negotiations appears to be linked to countries that have invested heavily in gasAbout a fifth of the world’s oil and liquefied natural gas (LNG) passed through the strait of Hormuz, a strip of sea less than 30 miles wide at its narrowest point, before it was in effect closed by the US-Israeli attack on Iran, which sent the price of oil soaring and left an estimated 20,000 seafarers on 2,000 vessels stranded.Their plight has shone a spotlight on the complex and dirty relationship between shipping and the fossil fuel industry. The sector is one of the most polluting, with most ship engines fuelled by what has been called the dregs of the oil refining process, heavy and carbon-intensive diesel too filthy for any other purpose. Shipping produces about 3% of global greenhouse gases, a portion set to rise as trade globalises further. Continue reading...

Study Converts Carbon Dioxide Into Long-Chain Chemicals for Jet Fuel

Researchers published a study in ACS Catalysis on April 15 detailing a process to convert carbon dioxide directly into long-chain chemicals suitable for jet fuel. The method essentially runs combustion in reverse, recombining waste gas with water to create energy-dense liquid fuel. The breakthrough addresses two major obstacles that have historically hindered this chemical process: carbon chain growth difficulties and low yields of valuable long-chain products.

Russian Scientists Discover Residual Arctic Lakes Emit Greenhouse Gases

Soil scientists at Tomsk State University discovered that residual small lakes in bowls of descended thermokarst lakes in Russia's Arctic Zone are significant sources of greenhouse gases. The research measured CO2 and methane concentrations across three sites in the Yamal Peninsula region, finding that shallow reservoirs release substantial carbon dioxide fluxes regardless of drainage age. The study suggests these residual basins should be included in climate monitoring and carbon cycle models as Arctic permafrost continues to thaw.
