Our ability to cool the planet takes humanity into unchartered territory. In a new paper published today, researchers discuss the big unknowns in a post net-zero world.

The war in Ukraine threatens to turn back the clock on Russia’s climate progress, with some calling on the country to leave the Paris Agreement and roll back environmental regulations.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.

Haphazard development of abattoirs without environmental and health considerations in Nigeria can only invite diseases – and potentially pandemics such as COVID-19.

As our planet warms, the number of air-conditioning units worldwide is expected to triple by 2050 – yet their use drives climate change. So how can we break the cycle?
On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.

This hot, acidic neighbor with its surface veiled in thick clouds hasn’t benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
The air up high is just really bad at ‘holding’ onto the radiation coming from the Sun, and the warmth passes straight through it on its journey toward the ground.

The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.

The 2016 bleaching on the Great Barrier Reef was the worst on record. Now a new analysis points the finger squarely at human-induced warming, and warns that the entire reef’s future is at stake.
Scientists monitor landscapes like Omulyakhskaya and Khromskaya Bays in northern Siberia closely.

Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
