A new way of measuring emissions may let the biggest polluters evade their responsibility to tackle climate change.
The most comprehensive Australian carbon budget assessment completed to date shows the nation flip-flops from source to sink of carbon emissions, depending on the prevailing conditions.
Releasing reflective particles into the upper atmosphere would help us tackle climate change – but it’s not without risk.
Record emissions are fast shrinking the remaining amount of carbon dioxide we can emit if we are to limit global warming. At current rates, we’ll use up the budget for a 1.5°C outcome in seven years.
Electric arc furnaces can use up to 100% scrap steel as its raw material, resulting in a significant reduction in emissions.
Carbon credits must be scrutinised – and none more so than credits for taking grazing animals off arid rangelands.
Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.
For a two-in-three chance of staying within 1.5°C, the budget shrinks to one-and-a-half years.
The Biden administration directed agencies to consider the cost of greenhouse gas emissions in their future purchasing and budget decisions. An example shows just how much is at stake.
New research reveals the environmental impact of keeping tropical fish as household pets – but there are ways to reduce it.
The results are intriguing, but analysing the atmospheres of exoplanets is no easy task.
Pretty much every kitchen can double as a chemistry set.
Ever wonder how soda manufacturers get the bubbles and fizz inside the can? A chemist explains some of the science behind the carbonation process. Hint − it involves carbon.
Can planting trees help us solve the climate crisis? Probably, but to what extent?
Most of the carbon disturbed by trawls is unreactive and difficult to convert to CO₂.
A longer growing season for trees, due to global warming, does not necessarily lead to an increase in wood production.
We want good news on climate change. But whales storing enough carbon needs more evidence.
After the Supreme Court overturned the Obama administration’s strategy for reducing power plant carbon emissions in 2022, the Biden administration is taking a narrower but still ambitious approach.
Carbon capture and storage could keep fossil fuel power plants running under newly proposed federal emissions standards, but it faces high hurdles.
Rising temperatures mean longer, earlier pollen seasons, but a bigger problem is what more carbon dioxide will do to the amount of pollen being released.
