Dr Rahmstorf said.

move against climate research has been denounced
by about 3000 scientists from
almost 60 nations, who have signed a petition sent to the Turnbull
government. They warn that Australia risks losing world-leading
talent and will undermine the ability to observe the changes of
the world's climate, particularly in the southern hemisphere.
chief executive Larry Marshall has said the two climate units
targeted for deep cuts will eventually increase staff but
numbers will be half current levels. The freed-up resources will
be used for other research priorities including studying
Australia's adaptation needs for the inevitable climate impacts
to come as the country warms.
