Former Energy Minister Chris Skidmore’s report into Net Zero calls for ambitious policies to drive energy transition, framing it as a huge economic opportunity to drive national growth. Using and conserving energy in the home is one theme the report tackles. We discuss home insulation with Colm Britchfield , policy advisor at E3G.

Dr Christine Cooper at Cutin University in Western Australia, found this marsupial is actually remarkably heat tolerant, and capable of handling temperatures which were previously thought to be lethal.
