It’s 20 years since we started blogging on climate here on RealClimate (December 10, 2004). We wanted to counter disinformation about climate change that was spreading through various campaigns. In those days it was an unusual move that prompted a welcome from Nature.

Operationalizing Climate Science
There is a need to make climate science more agile and more responsive, and that means moving (some of it) from research to operations.

Science is not value free
An interesting commentary addressing a rather odd prior commentary makes some very correct points.

The title of this post might seem like a truism, but for about a decade some people have claimed the opposite, and many people have spent much time and effort trying to understand why. Much of that effort was wasted.

Phantastic Job!
A truly impressive paper was published this week with a new reconstruction of global temperatures over the last ~500 million years.

Oh My, Oh Miocene!
A recent paper suggested that ‘climate sensitivity’ derived from a new paleo-CO2 record is around 7.2ºC (for equilibrium climate sensitivity ECS) and ~13.9ºC (Earth System Sensitivity – ESS) for a doubling of CO2. Some press has suggested that this means that “Earth’s Temperature Could Increase by 25 Degrees” (F). Huge if true! Fortunately these numbers should not be taken at face value, but we need to dig into the subtleties to see why.

How should we allocate resources for climate modelling if the goal is to improve climate-related decisions? Higher resolution, machine learning and/or storylines? A call for a deeper discussion on how we should develop the climate modelling toolbox.
