China-based emissions of three potent climate-warming greenhouse gases spiked in past decade
Two studies pinpoint their likely industrial sources and mitigation opportunities. When it comes to heating up the planet, not all greenhouse gases are created equal. They vary widely in their global warming potential (GWP), a measure of how much infrared thermal radiation a greenhouse gas would absorb over a given time frame once it enters the atmosphere.

A new explanation for Jupiter's great, shrinking 'Spot'
A new explanation for Jupiter’s great, shrinking ’Spot’
A steady diet of smaller storms may be what fuels Jupiter's Great Red Spot - and a decline in small storms may be causing it to shrink. Jupiter's Great Red Spot - the biggest windstorm in the solar system - is shrinking, and a new study may help explain why. Located in Jupiter's southern hemisphere, the Great Red Spot is a swirling, red-orange oval of high pressure more than 10,000 miles wide.

The dawn of the Antarctic ice sheets
The dawn of the Antarctic ice sheets
For the first time, the recovery of unique geological samples combined with sophisticated modelling provides surprising insights into when and where today's Antarctic ice sheet formed. In recent years global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica.

Mozambican Woodlands could store more than double the carbon previously estimated
Mozambican Woodlands could store more than double the carbon previously estimated
The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists including UCL researchers. The research, led by carbon data provider Sylvera and published in Nature Communications Earth & Environment , found that miombo woodlands, which span large areas of Sub-Saharan Africa, store 1.5 to 2.2 times more carbon than had previously been estimated by standard methods.

The formation of the Antarctic ice floes
The formation of the Antarctic ice floes
An international research team led by Silvia Spezzaferri from the University of Freiburg has discovered why the Antarctic polar ice cap is melting faster on the western side of the continent than on the eastern side. New drillings and sophisticated modeling have shown that this phenomenon can be traced back to the original formation of the ice sheet 34 million years ago .

The Gulf Stream is wind-powered and could weaken from climate change
The Gulf Stream is wind-powered and could weaken from climate change
New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study led by UCL researchers. The research, published in Nature, found that during the last ice age about 20,000 years ago, the Gulf Stream was stronger than today because of more powerful winds across the subtropical North Atlantic.

James Webb Space Telescope provides first hints of evidence of the existence of an ocean exoplanet
A team of CNRS planetary scientists 1 working in collaboration with astronomers from the University of Montréal has presented first evidence that the temperate exoplanet LHS 1140b could be an ocean world. Over the past few years, the planet, which is located around 48 light-years from the Solar System in the constellation Cetus, has been observed by the Hubble, Spitzer and TESS space telescopes, as well as by the ESPRESSO instrument mounted on the VLT telescope in Chile.

Weaker ocean circulation could enhance CO2 buildup in the atmosphere
New findings challenge current thinking on the ocean's role in storing carbon. As climate change advances, the ocean's overturning circulation is predicted to weaken substantially. With such a slowdown, scientists estimate the ocean will pull down less carbon dioxide from the atmosphere. However, a slower circulation should also dredge up less carbon from the deep ocean that would otherwise be released back into the atmosphere.
