Plant-based jet fuel could reduce emissions by 68%

15 Oct 21 - Replacing petroleum-based aviation fuel with sustainable aviation fuel derived from a type of mustard plant can reduce carbon emissions by up to 68%, according to new research from University of Georgia scientist Puneet Dwivedi.

Iron battery breakthrough could eat lithium’s lunch

11 Oct 21 - The world’s electric grids are creaking under the pressure of volatile fossil-fuel prices and the imperative of weaning the world off polluting energy sources. A solution may be at hand, thanks to an innovative battery that’s a cheaper alternative to lithium-ion technology.

Plastic and climate crises are linked

30 Sep 21 - For the first time, an interdisciplinary team of scientists collected evidence on how both global problems exacerbate one another, creating a dangerous cycle. The researchers identified three significant ways that the climate change crisis and marine plastic pollution are connected.

Seagrass: The plant that removes carbon 30 times faster than a rainforest

30 Sep 21 - WWF has teamed up with Sky to promote their ‘Force for Nature’ campaign, an effort to repopulate the UK’s coasts with carbon-capturing seagrass.

Waste material from bauxite mining helps create climate-friendly cement

19 Aug 21 - A climate-friendly cement has been developed that produces up to two-thirds fewer carbon emissions during its production than conventional cement.

Progress being made on lowering cost of green hydrogen


21 Jul 21 - For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source -- splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low cost led to poor performance.

NASA finds definitive proof of climate change

6 Apr 21 - It may come as a surprise, given the extensive body of evidence connecting humans to climate change, that directly-observed proof of the human impact on the climate had still eluded science. That is, until now.

Temperatures to soar for half a billion people

30 Mar 21 - Many millions of people − among them some of the world’s poorest − will be exposed to potentially lethal temperatures on a routine basis. At worst, the mercury could reach 56deg by 2100.

Nature left alone offers more than if we exploit it

24 Mar 21 - Save nature, save money. It’s a simple argument. Wilderness cleared and ploughed offers us less than nature left alone.

Why fish-trawling should be in national carbon accounts

18 Mar 21 - Bottom-trawling for fish releases more carbon dioxide each year than Germany does, yet is not included in national carbon accounts, scientists say.

Carbon emissions slow, but not nearly fast enough

9 Mar 21 - Five years after a planet-wide vow to reduce carbon emissions, it happened; in 2020, the world’s nations pumped only 34 billion tonnes of carbon dioxide into the atmosphere, a drop of 2.6 billion...

Land worth more if left to nature

9 Mar 21 - Nature-rich sites such as woods and wetlands could be more valuable than farming because of the ecosystem services they provide, scientists say.

Fiercer, more frequent fires may reduce carbon capture by forests

26 Feb 21 - More fierce and frequent fires are reducing forest density and tree size and may damage forests’ ability to capture carbon in the future, according to a global study.

'Science-based' targets are no such thing - former adviser

25 Feb 21 - One of the instigators of an influential climate initiative for big business has gone public with criticism of its target-setting process, saying it does not measure up to its ambition.

Leveraging AI to fight climate change

19 Feb 21 - International organisations, researchers and data scientists say artificial intelligence and big data are critical to combat years of promises but inadequate action on the climate, biodiversity and...

Scientists warn over misuse of climate models in financial markets

10 Feb 21 - Misuse of climate models could pose a growing risk to financial markets by giving investors a false sense of certainty over how the physical impacts of climate change will play out, according to the...

2020 one of the hottest and driest years we've had

12 Jan 21 - New Zealand’s average temperatures continue to climb, with latest climate data showing 2020 was one of the country’s warmest years on record.

Global emissions at new record

10 Dec 20 - Greenhouse gas emissions reached a new high last year, putting the world on track for an average temperature rise of 3deg, a new United Nations report shows.

Research spending doesn't match priorities - report

10 Dec 20 - There’s a serious mismatch between what New Zealand’s Government identifies as the most pressing environmental issues, including climate change and freshwater quality, and the investments in...
