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.

The clock tracks global emissions and temperature data, and uses the most recent five-year emissions trend to estimate how much time is left until global warming reaches the 1.5 C threshold.
Take a closer look at what’s driving climate change and how scientists know CO2 is involved, in a series of charts examining the evidence in different ways.
