The case for large-scale technologies that reflect solar radiation back into space rests on global warming’s grim reality.

Jika negara-negara pengekspor batu bara terbesar melarang pembukaan tambang batu bara baru, mereka dapat mendorong peralihan ke energi terbarukan – dan mendapatkan manfaat dari hal tersebut.
If the biggest coal exporters banned new coal mines, they could drive the shift to renewables – and benefit while they do it.
Organisms that produce synthetic fuel and suck carbon out of the air are just some of the possibilities of ‘engineering biology’ – if policymakers can shepherd the industry towards success.
A new report explores options for managing the period after global warming exceeds 1.5°C. This is called ‘climate overshoot’, because we’re pushing past the safe zone into dangerous climate change.
The best thing to do is to stop emitting carbon. However, preserving a safe climate will likely require us to go further.
The Greens have successfully cast themselves as the party of climate science. But to hit their climate goals they may need to become even more radical, by embracing technologies like nuclear power.
Western leaders and activists should show humility and allow themselves to be guided by local organisations if they wish to be effective in promoting same-sex rights.
Given existing technologies, expanding access to electricity almost always increases CO2 emissions. There are real trade-offs between addressing poverty and climate change.
Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
