Em breve, poderá ser possível reduzir a intensidade de ciclones pulverizando partículas na atmosfera acima de uma tempestade em formação. Mas os altos custos e a própria marcha acelerada do aquecimento global não facilitarão esse trabalho. NASA

Clima: é possível eliminar os furacões? Sim, mas ainda falta muita pesquisa ‑ e muito dinheiro

Em breve, poderá ser possível reduzir a formação e a intensidade de ciclones pulverizando partículas na atmosfera acima de uma tempestade em formação. Mas a tecnologia abre uma caixa de pandora

Net zero by 2050? Too late. Australia must aim for 2035

We’ve wasted a lot of time delaying climate action. As the damage becomes ever clearer, it’s time to accelerate the transition.

Better than net zero? Making the promised 1.2 million homes climate‑friendly would transform construction in Australia

We can construct buildings that reduce atmospheric CO₂ by more than their lifetime emissions. They now don’t cost much more – and a project involving 1.2 million homes would drive costs down further.

In the future, we could snuff out cyclones. But weather control comes with new risks

It may soon be possible to reduce cyclone formation and intensity by spraying particles into the atmosphere above a forming storm. But the technology opens up a can of worms

New IPCC report shows Australia is at real risk from climate change, with impacts worsening, future risks high, and wide‑ranging adaptation needed

We are no longer in typical conditions. Climate change is already damaging human and natural systems we hold dear in Australia.

Mass starvation, extinctions, disasters: the new IPCC report’s grim predictions, and why adaptation efforts are falling behind

The IPCC is the global authority on climate change. Their new report paints a worrying picture of climate impacts already affecting billions of people, economies and the environment.

La ONU manda un SOS: urge limitar el calentamiento global a 1,5°C para evitar una catástrofe

Limitar el calentamiento global a 1,5 grados centígrados es un reto difícil, pero aún está a nuestro alcance, según un informe histórico del Grupo Intergubernamental de Expertos sobre el Cambio Climático encargado después de la cumbre de París de 2015.

The UN’s 1.5°C special climate report at a glance

Here are the essential facts from the UN’s special report on climate change.

Climate scientists and policymakers need to trust each other (but not too much)

Politicians are always being told to trust what climate scientists are telling them. But can you have too much of a good thing? What happens when the exchange of ideas becomes too cosy?
