Nature Reviews Earth & Environment

Do you find it incredibly difficult to keep track of the latest developments in Earth and environmental sciences? With an ever increasing volume of scientific literature being published, that’s no surprise. So, if you’re new to a field, want to delve deeper into a topic, or if you just want to see what the most …

A breathing planet off balance

A breathing planet off balance

Our atmosphere. Just a thin layer of gases surrounding our planet. Absorbing solar radiation. Retaining heat to warm the Earth’s surface. A delicate mixture of gases separating life on Earth from the rest of the cosmos. But when this mixture of gases gets out of balance, the temperature rises and alters our climate. Carbon is …

A Look Back at the Montreal Protocol

A Look Back at the Montreal Protocol

music Molina and Rowland made some very important points in their 1975 paper. The main one being that the lifetime of the chloroflurocarbons is extremely long-50 to 100 years. There’s no way to destroy these gases. Once you put them in, they’ve got nowhere to go except up to the ozone layer where they’re going …

Ocean Confetti!

In many ways, plastic is the perfect material: we can make it strong and rigid enough to build spaceships and replace bones, or thin and flexible enough to make shopping bags that weigh as much as a nickel but carry up to 17 pounds. And unlike other materials, plastic doesn’t rust or rot — it …

The Faint Young Sun Paradox!

The Faint Young Sun Paradox!

Hi, this is Emily. In 1972, Carl Sagan and a colleague discovered something that’s come to be known as the faint young sun paradox: according to stellar physics, our sun has been growing brighter over time, thanks to increasing hydrogen fusion in the star’s core. This means that the sun that shined on early Earth …

How Do Greenhouse Gases Actually Work?

How Do Greenhouse Gases Actually Work?

The earth and the moon are basically the same distance from the sun, yet temperatures on the moon average an unlivable -18°C, and even deadlier, they range from -170°C during lunar night to 100°C at lunar noon, regularly exceeding both the coldest and hottest temperatures ever recorded on Earth. And while the days and nights …
