Antarctica’s delicate ecosystem could be under threat from invasive species.
A warming Earth could see invading species arrive in Antarctica via the floating "taxi service" of the sea. That could be a threat to the southern continent's delicate ecosystem.
Some parts of Antarctica’s Totten Glacier are more stable than others.
New mapping shows how Antarctica's huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.

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.
So many questions on climate change.
Research showing that more than 90% of climate scientists agree that we’re causing global warming prompted plenty of questions. And the authors are only too happy to answer.
More than 160 nations will sign the Paris Agreement on its opening day – a record for a United Nations treaty.
More than 160 countries are expected to sign the Paris Agreement in New York on April 22. But enough countries will also need to ratify the treaty domestically before it can become international law.
The Paris climate agreement will be open for signing at the UN’s New York headquarters for the next year, starting tomorrow.
Australia will be one of more than 160 nations formally signing the Paris climate agreement in New York this week. But delivering on those promises is what really counts.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
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.
We still don’t know enough about questions such as where the tipping points are for Arctic ice melt.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
The Urban Heat Island is an inevitable outcome of urbanisation – but as the Earth gets warmer, that's cause for concern.
Geoengineering could help regions affected by climate change deal with the problem.
Wildfires devastated large parts of California and the West, which has been suffering from a historic drought.
Thanks to El Niño and climate change, last year broke temperature records – and reduces any importance attached to the global warming 'hiatus.'
People living with chronic illnesses are more vulnerable to heat effects.
Rising temperatures affect people living in the developing world differently to those living in Europe and North America.

Iron and nutrients from Antarctica's bedrock are carried into the oceans – nourishing entire food webs.
Extreme drought, a predictable impact of El Niño, fuels wildfires on the island of Borneo on October 14.

The third-ever 'super' El Niño is under way. Here's how it will affect your region in the US and how global warming affects this and future El Niños.
The pressure to pledge for 1.5℃ grew throughout the Paris summit.
The inclusion of a 1.5℃ goal in the Paris climate deal might have surprised some observers. But in reality, the diplomatic groundwork was laid years before.
Countries have agreed to keep the rise in global temperatures to “well below 2°C”.
The United Nations Framework Convention on Climate Change finally came to an agreement. Here are the key points.
1.5 or 2 degrees? What matters is how we get there.
Saleemul Huq (left) says the world’s vision should be to help everyone with climate change - even the very poorest.
A majority of countries want visionary action rather than pragmatism at the Paris climate talks, says the International Institute for Environment and Development's Saleemul Huq.
At yesterday’s COP21 science briefing, University of Reading climate scientist Ed Hawkins displayed a chilling (pun intended) colour-coded world map. Nation by nation, it showed which countries are already…
