Real Climate: Joy plots for climate change

This is joy as in ‘Joy Division’, not as in actual fun. Many of you will be familiar with the iconic cover of Joy Division’s Unknown Pleasures album, but maybe fewer will know that it’s a plot of signals from a pulsar (check out this Scientific American article on the history). The length of the

Real Climate: The climate has always changed. What do you conclude?

Probably everyone has heard this argument, presented as objection against the findings of climate scientists on global warming: “The climate has always changed!” And it is true: climate has changed even before humans began to burn fossil fuels. So what can we conclude from that? A quick quiz Do you conclude… (1) that humans cannot

Real Climate: Climate Sensitivity Estimates and Corrections

You need to be careful in inferring climate sensitivity from observations. Two climate sensitivity stories this week – both related to how careful you need to be before you can infer constraints from observational data. (You can brush up on the background and definitions here). Both cases – a “Brief Comment Arising” in Nature (that

Real Climate: Why global emissions must peak by 2020

(by Stefan Rahmstorf and Anders Levermann) In the landmark Paris Climate Agreement, the world’s nations have committed to “holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels”. This goal is deemed necessary to

Real Climate: Nenana Ice Classic 2017

As I’ve done for a few years, here is the updated graph for the Nenana Ice Classic competition, which tracks the break up of ice on the Tanana River near Nenana in Alaska. It is now a 101-year time series tracking the winter/spring conditions in that part of Alaska, and shows clearly the long term

Real Climate: Snow Water Ice and Water and Adaptive Actions for a Changing Arctic

The Arctic is changing fast, and the Arctic Council recently commissioned the Arctic Monitoring and Assessment Programme (AMAP) to write two new reports on the state of the Arctic cryosphere (snow, water, and ice) and how the people and the ecosystems in the Arctic can live with these changes. The two reports have now just

Real Climate: Judy Curry’s attribution non-argument

Following on from the ‘interesting’ House Science Committee hearing two weeks ago, there was an excellent rebuttal curated by ClimateFeedback of the unsupported and often-times misleading claims from the majority witnesses. In response, Judy Curry has (yet again) declared herself unconvinced by the evidence for a dominant role for human forcing of recent climate changes.

Real Climate: Predictable and unpredictable behaviour

Terms such as “gas skeptics” and “climate skeptics” aren’t really very descriptive, but they refer to sentiments that have something in common: unpredictable behaviour. Statistics is remarkably predictable The individual gas molecules are highly unpredictable, but the bulk properties of the gases are nevertheless very predictable thanks to physics. More specifically the laws of…

Do we need a new venue for post-publication comments and replications? Social media is full of commentary (of varying degrees of seriousness) on the supposed replication crisis in science.

Real Climate: 2016 Temperature Records

To nobody’s surprise, all of the surface datasets showed 2016 to be the warmest year on record.

Coming as this does after the record warm 2015, and (slightly less definitively) record warm 2014, the
