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.
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.
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.
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.
Pollution from more frequent floods and wildfires – exacerbated by the warming climate – is threatening human health and poses particular risks to the brain.
