While carbon dioxide removal from the air is not a replacement for emissions reductions, it can supplement these efforts. Experts are continually researching the best ways to do this.
Some industries, including steel and cement, emit carbon dioxide as part of the manufacturing process, and could benefit from carbon capture technologies.

Carbon capture technologies have been labelled as a distraction. But as we enter the all-hands-on-deck phase of tackling climate change, they must not be ignored.
If successful, solar geoengineering would would reduce the amount of sunlight that reaches the Earth’s surface and warms the planet.

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

Earth’s has gone through major climate changes in the past. They happened on time scales of millions of years and triggered mass extinctions. Our emissions are changing the climate much faster.
Household actions lead to changes in collective behaviour and are an essential part of social movements.

President Trump has confirmed that the US will leave the Paris Agreement on climate change on the earliest allowable date: Nov. 4, 2020. Will this hobble efforts to slow global warming?
Legislative action regarding vehicle emissions is overdue, and needs urgent attention by the federal government.

In the eastern reaches of Siberia, scientists discovered plants with exceptional cold tolerance that could be the key to sustainable bioenergy production.
Australia will have to regulate its considerable shipping industry.
