For wetland plants, sea-level rise stamps out benefits of higher carbon dioxide

Today 11:45am - Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change—rising carbon dioxide (CO2)—could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise. That helpful side effect is disappearing, they discovered in a new study published May 18.

Even if we miss the 1.5°C target we must still fight to prevent every single increment of warming

13 May 22 - Is it game over for our attempts to avert dangerous climate change? For millions of people in India and Pakistan the answer is clearly yes as they continue to suffer from a record-breaking spring heatwave that is testing the limits of human survivability.

Trees aren’t a climate change cure-all – 2 new studies on the life and death of trees in a warming world show why

13 May 22 - The results of two studies published in the journals Science and Ecology Letters on May 12, 2022 – one focused on growth, the other on death – raise new questions about how much the world can rely on forests to store increasing amounts of carbon in a warming future. Ecologist William Anderegg, who was involved in both studies, explains why.

It’s easier to break a bog than to repair it—but it’s still a carbon bargain.

12 May 22 - What do bogs in Indonesia and mangrove forests in Central America have in common? They are both powerful carbon sponges, capable of sucking up greenhouse gases at up to five times the rate of a forest. And they are both disappearing at alarming rates.

'Fifty-fifty chance' of breaching 1.5C warming limit

11 May 22 - UK Met Office researchers say that there's now around a fifty-fifty chance that the world will warm by more than 1.5C over the next five years.

Atmospheric CO2 hits another all-time high

10 May 22 - Atmospheric carbon dioxide levels measured at Hawai’i’s Mauna Loa Observatory breached 420 parts per million (ppm) in April for the first time in human history.

Tropical vegetation benefits less from elevated atmospheric carbon dioxide than researchers previously thought

6 May 22 - Carbon dioxide is known to have a fertilizing effect on plant growth, and the gas is often added to greenhouse crops to help improve yields.

Gene-editing breakthrough could cut ruminant methane

6 May 22 - Scientists have successfully switched on a plant gene in feed crops that could help reduce methane emissions from cattle and sheep.

Hydrogen 11 times worse than CO2 for climate: new report

12 Apr 22 - Hydrogen will be one of humanity's key weapons in the war against carbon dioxide emissions, but it must be treated with care. New reports show how fugitive hydrogen emissions can indirectly produce...

A bold idea to stall climate crisis - build better trees

29 Mar 22 - Changing the genetic makeup of trees could supercharge their ability to suck up carbon dioxide. But are forests of frankentrees really a good idea?

The impact of deforestation goes beyond carbon emissions: new study

28 Mar 22 - The deforestation of tropical areas is even more impactful on the climate cycle than previously thought, according to a March 2022 study published in

These solar panels pull in water vapor to grow crops in the desert

2 Mar 22 - Using a unique hydrogel, scientists in Saudi Arabia created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity.

Engineered bacteria produce chemicals with negative carbon emissions

22 Feb 22 - Bacteria engineered to turn carbon dioxide into compounds used in paint remover and hand sanitiser could offer a carbon-negative way of manufacturing industrial chemicals.

Fatal distraction: the problem with the methane pledge

22 Feb 22 - Over the past year, the world has experienced severe heatwaves, wildfires, and drought. As global temperature continues to creep upwards, these events will become more frequent and more extreme.

Forests follow unexpected—and surprisingly fast—paths to recovery

17 Feb 22 - A new study found that carbon, nitrogen and soil density in cleared forests reached 90% of levels in untouched forests after 1 to 9 years. They key was leaving them alone.

‘Dangerously fast’ methane increase suggests feedback mechanism may have begun

15 Feb 22 - Methane concentrations in the atmosphere have risen at a “dangerously fast” rate and now exceed 1,900 parts per billion, prompting some researchers to warn that climate change itself may be driving...

Polar bear inbreeding and bird 'divorces': Weird ways climate change is affecting animal species

14 Feb 22 - The world's biodiversity is constantly being threatened by warming temperatures and extreme changes in climate and weather patterns.

Scientists raise alarm over ‘dangerously fast’ growth in atmospheric methane

11 Feb 22 - As global methane concentrations soar over 1,900 parts per billion, some researchers fear that global warming itself is behind the rapid rise.

Rethinking how to measure methane's climate impact

10 Feb 22 - Like boxers whose punching power declines over their careers, greenhouse gasses lose their warming impact at different rates. So, to compare gasses' climate changing potential to the most common...
