Solar geoengineering could theoretically cool the Earth to slow global warming, and it has been controversial. Still, countries should research its risks and benefits.

Soot from aeroplane exhausts can linger in the atmosphere, seeding ice clouds which trap heat.
When big investors like Blackrock get worried about their returns, they have the power and incentive to make fossil fuel companies take action.
If the G7 is serious about stopping global warming, it could start by acknowledging who and what is causing it.
A complete switch to biofuels is neither feasible nor desirable, but they could replace some fossil fuels in transport and heating. If biofuels are produced from waste products, that’s even better.
Heat pumps are the technology of choice for heating and cooling buildings more efficiently and with fewer carbon emissions than furnaces and air conditioning.
A new study shows how we can meet the goals of the Paris Agreement by changing the value of different greenhouse gases over time.
As global oil consumption drops, oil companies are pivoting to petrochemicals, and could crowd out bio-based alternatives.
Tesla’s stance has also shone the spotlight further onto the carbon footprint of cryptocurrency – an issue that will not go away soon.
The Morrison government could have backed Australia’s clean energy sector to create jobs and stimulate the post-pandemic economy. Instead, it’s sending the nation on a fool’s errand.
The lead author of a new UN report on methane explains the findings and how oil and gas companies could be making money and saving the climate at the same time.
To achieve sustainable growth under the constraint that consumption is independent from the use of natural resources, we must move along the path of qualitative growth.
Drilling instead of tilling the soil to plant seeds could help the ground store more carbon.
The snail’s pace of action in this year’s federal budget on climate is out of step with the urgency of the climate and income inequality crises.
Bill C-12 is a step in the right direction, but its not enough to meet Canada’s goal for a decarbonized economy.
Hearing about climate change prompts people to buy more stuff, which increases their environmental footprint. Rituals that inspire gratitude for nature can help reduce the desire to over-consume.
The Earth should be safe (and habitable) for a few billions of years, but we still need to worry about the impact now of just a few degrees of global warming.
Scientists previously underestimated aquatic methane emissions. We must use this new information to stop methane derailing our attempts to stabilise the Earth’s temperature.
Discord and doubt are the last things the world needs at this critical moment.
CEOs, including at oil companies and airlines, are relying on trees and oceans to capture and store carbon for them, but the numbers don’t add up.
