Why carbon dioxide has such outsized influence on Earth’s climate

Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?

How we can keep our planet cool even as A/C use rises

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. NASA/SDO, AIA

Why we need to get back to Venus

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.

Eating insects is good for you — and the planet!

Insects are high in protein and rich in other nutrients and, unlike beef and other livestock, have little impact on climate.

Not everyone cares about climate change, but reproach won’t change their minds

In the end, climate policy didn't swing the federal election, and for those on the losing side it can be tempting to play the blame game. But listening and respect are much better ways to move forward.

Why there’s more greenhouse gas in the atmosphere than you may have realised

Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.

Explaining the increase in coal consumption worldwide

While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.
