The three-minute story of 800,000 years of climate change with a sting in the tail

The current rise in atmospheric carbon dioxide levels is unprecedented in the past 800,000 years. As our video explains, ice cores track human changes to the atmosphere that are far beyond natural.

What is a pre-industrial climate and why does it matter?

The Paris climate agreement aims to keep restrict global warming to within 2℃ above 'pre-industrial levels'. But what does that mean, exactly?

Whose word should you respect in any debate on science?

Modern science can be difficult or complex for one person to understand and verify, especially a non-scientist. So who should we believe when scientific evidence is met with denial?

Explainer: the search for Earth’s ‘missing fingerprint’

Without understanding why the 'fingerprint' has failed to appear our predictions about global warming - as carbon dioxide concentrations increase - are uncertain.

Climate meme debunked as the ‘tropospheric hot spot’ is found

Climate models have been criticised because observations could not find the predicted "hot spot" of strong warming in the troposphere. But analyses now show that the tropospheric hot spot is indeed real.

Can people power drive action on climate change?

Humans have so much influence over the global environment today that we have crossed a major threshold in Earth’s long history, entering a new stage in geological time which some scientists call the Anthropocene…

New Zealand’s Southern Alps have lost a third of their ice

A third of the permanent snow and ice of New Zealand’s Southern Alps has now disappeared, according to our new research based on National Institute of Water and Atmospheric Research aerial surveys. Since…

The ‘pre-Holocene’ climate is returning – and it won’t be fun

A string of events earlier this year provided a sobering snapshot of a global climate system out of whack. Europe suffered devastating floods, Britain’s coastline was mauled, and the polar vortex cast…

IPCC preview: deep trouble brewing in our oceans

Scientists are meeting this week in Yokohama, Japan, to finalise and approve the latest report from the Intergovernmental Panel on Climate Change’s Working Group II – the part of the IPCC process that…

US cold wave implies nothing about global warming

The central and eastern US has just been in the midst of a major cold wave, with large regions dropping below zero F (-17.7C) and wind chills reaching below -30F (-34C). That is fact. The problem is that…

Masking and unmasking of global warming by aerosols

Climate scientists have established a convincing case for the link between increasing concentrations of greenhouse gases and observed warming of the Earth since the 19th century. The Fifth Assessment Report…

Arctic sea ice levels reach seasonal low

Arctic sea ice extent has dropped to a seasonal low and the sixth lowest level since the beginning of its 35-year satellite…
We’ll never know how much the globe will warm, but we have a pretty good idea: what are we waiting for? Luis Ramirez

Uncertainty no excuse for procrastinating on climate change

Today we released research which reduces the range of uncertainty in future global warming. It does not alter the fact we will never be certain about how, exactly, the climate will change. We always have…
