Climate finance: it’ll be cheaper in the long run if poorer countries receive it as a matter of urgency

Early investments generate rapid cost reductions, while further delay simply slows innovation and compounds the climate crisis.

Forests can’t handle all the net-zero emissions plans – companies and countries expect nature to offset too much carbon

Yes, trees and soils can absorb and store carbon, but the carbon doesn’t stay stored forever. That’s one of the problems with how net-zero plans for the climate are being designed.

The climate crisis gives science a new role. Here’s how research ethics must change too

Research ethics focus on avoiding wrongdoing, having been developed largely in response to biomedical scandals. Climate change puts the onus on researchers to add ‘do good’ to ‘do no harm’ principles.

A 150-year-old note from Charles Darwin is inspiring a change in the way forests are planted

Charles Darwin’s ideas about diversity of plants growing together is now inspiring researchers create healthier forests.
According to recent estimates, only 500 billion tonnes of carbon dioxide can be emitted from 2020 onwards if we are to stay below the 1.5 C threshold. Global emissions have already hit 80 billion tonnes since then. (AP Photo/Alberto Pezzali)

Climate clock reset shows the world is one year closer to 1.5 C warming threshold

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.

South Africa’s power utility Eskom: how does it stack up in the pollution stakes?

To improve air quality, a combination of efforts is needed including reducing Eskom’s emissions, investing in cleaner sources of energy, and reducing emissions.
