Research brief: New protocol aims to improve the quality and communication of extreme event attribution

This paper aims to catalogue the steps the authors have found make up a successful framework for event attribution analyses. The hope is that this paper will be useful for those considering how to undertake such work themselves and to highlight some of the potential issues and pitfalls that can arise along the way.

Record Breakers: What causes the longest, largest and most intense ocean heatwaves

In a new study published in Nature Scientific Reports, a group of oceanographers, atmospheric scientists, ecologists and fisheries experts got together to identify the most severe marine heatwaves over recent decades. The objective was to understand what triggered these events and led to their ultimate demise.

Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.

An international review of IPCC reports since 2001 has found that as the science has improved with each report, a trend has appeared showing climate related impacts like heatwaves, the collapse of the West Antarctic ice sheet and coral bleaching are likely to occur at lower global mean temperatures than estimated in earlier reports.

Heatwave trends accelerate worldwide

The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950’s. The research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons.
