Thanks to their high concentrations of phytoplankton, African lakes emit less CO2 than their boreal counterparts, with important consequences for climate modelling.
Thanks to humans, the concentration of planet-warming carbon dioxide in the atmosphere is now 50% higher than before the industrial era. These gases are raising Earth’s temperature.
Our research shows NZ’s potential to burn forestry waste and capture the emissions in geothermal wells. But we’ll need new partnerships between power generators, manufacturers and the forestry sector.
When groundwater comes to the surface, sunlight and air convert organic molecules to greenhouse gases. That’s going to be a problem as we will need this water more as the world warms.
Rising carbon dioxide in the atmosphere may be a boon for maize crops in tropical growing regions like those found in much of Africa.
The Earth is a resilient planet, but people are altering it in ways that may take centuries to reverse.
Using our oceans as carbon sinks could help achieve climate goals set in the most recent IPCC report.
While carbon dioxide removal from the air is not a replacement for emissions reductions, it can supplement these efforts. Experts are continually researching the best ways to do this.
The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.
New breakwater designs and more sustainable materials can cut the carbon cost of coastal defences by 40%.
Maintaining ecological balance in savannas is essential
Rising temperatures mean longer, earlier pollen seasons, but the bigger problem is what carbon dioxide will do to the amount of pollen being released. A 200% increase is possible this century.
The reduction of inequality is crucial from an ethical point of view as well as the fact that will open new possibilities on how to tackle climate change.
His theory, based on years of detailed climate and weather data, became known as the Callendar Effect. Today we call it global warming.
It’s time to think about other sources, such as carbon capture and bioethanol production.
Plan to cut emissions quickly, use offsets sparingly and set broader goals for improving society.
Klaus Lackner is finding new ways to cut the technology’s high costs and energy demand, and he’s about to launch the first ‘mechanical tree’.
By measuring emissions in real time, cities can take stronger action against air pollution and global warming.
Critics say investing in carbon capture and storage means betting on technology that’s not yet proven to work at scale. Using liquid marbles could make a huge difference.
Soaking up and storing CO₂ is not just a question of technology.
