Research brief: How to incorporate increased vapour pressure deficit into climate models

With projected increases in temperature in the future, the amount of water vapour that can be held at saturation – before it condenses into clouds, dew or water film – increases exponentially. As this deficit increases plants tend to close their stomata, which reduces water fluxes into the boundary layer. Do models currently capture the observed leaf-level response to increasing vapour pressure deficit? What about at very high levels of this deficit?

Research brief: Evaluating Himawari-8 cloud products

While the data from Himiwari-8 provides very useful data on clouds at relatively high resolution, researchers need to know if it produced any biases, particularly around cloud-top height and cloud-top temperature, whose roles are critical in shaping Earth’s climate. CLEX researchers and Australian colleagues compared the Himawari-8 data for both of these measures with existing datasets.

Enter the Plastisphere

Intergenerational equity was the theme of last weekend. On Friday I attended the Climate Strike in Melbourne. The crowd was massive as people of all ages and all walks of life gathered to tell the leaders of the world that we wanted real action on climate change.

Briefing note 009: Does global warming cause droughts, drying or increased aridity?

In an hour-long talk to a business forum, Andy Pitman said: “there is no link between climate change and drought”. Given the audience were not climate scientists, or interested in the physics of the climate, this statement was one word too brief. Andy fully admits he should have said: “there is no direct link between climate change and drought”.
