To fight global warming we will soon have to try to remove carbon dioxide from the skies or find ways to reflect the Sun’s heat. Such radical paths must be examined, but risky experiments avoided.
Some geoengineering techniques are better understood than others. The US is investing in capturing carbon dioxide from the air, but ideas to block the Sun’s rays are raising big concerns.
With tourists flocking in droves to ‘experience’ heat waves, perhaps it’s time for everyone to take a good hard look at their individual contribution to global warming.
Airlines are investing in sustainable biofuel startups and starting to uses alternative fuels, including cooking oil, ag waste and corn ethanol. But biofuels alone won’t be enough, research shows.
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
Carbon offsetting is often met with scepticism, but a new report suggests that if correctly designed it can be an important part of the net zero transition.
From pulling carbon dioxide out of the air to turning water into fuel, innovators are developing new technologies and pairing existing ones to help slow global warming.
Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.
The UN’s panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
