The level of carbon dioxide in the atmosphere is rising faster than at any point in the past 55 million years.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
Bureau of Meteorology
Atmospheric carbon dioxide measurements at Tasmania’s Cape Grim and Antarctica’s Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
Green planet: tropical rainforests have produced more growth in response to rising carbon dioxide.

Half of the world’s vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Glacier melt is one of the major contributors to global sea level rise.

Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn’t know how much of that was due to us, until now.

Working out how Mars’s carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.
Coral bleaching in March 2016. Rapid rises of greenhouse gases in the past have been linked to major extinctions in the oceans.

Carbon dioxide is rising faster than any time in the past 66 million years. Rapid rises in the past have been linked to mass extinctions.
Livestock ‘digestion’ produces nearly 3 billion tonnes of greenhouse gases each year.

Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
An open-cut coal mine in the Hunter Valley.

Methane is a stronger greenhouse gas than carbon dioxide, and Australia’s coal mines are a major source.
Million-year-old ice likely lies more than 3km below Antarctica’s surface.

Ice cores tell us vital information about how the world’s climate has changed - and how it will change in the future.
The Great Barrier Reef is made up of thousands of individual reefs.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
By putting a temporary halt to Obama’s cornerstone climate policy, the Supreme Court puts the next president in the driver’s seat.

If shipping and aviation don’t rein in their emissions it could seriously jeopardise our goal of preventing more than 2°C of warming.
