Functions and status of earth’s biomes that regulate
planetary resilience

The polar regions regulate
global temperature, regional
climate systems and ocean
circulation. Melting faster
than anticipated.
The world’s temperate organic
systems (such as permafrost)
act as carbon & methane sinks
and generate oxygen. Faster
than anticipated thawing of
permafrost & methane release
The World’s rainforests act
as carbon sinks, provide
moisture feedback, are
banks for genetic diversity
and generate oxygen. In
rapid decline but the rate
has declined somewhat.
Temperate forests act as carbon
sinks, regulate rainfall patterns
& generate oxygen. Relatively
stable but concern over rate of
deforestation in Russia and
severe warming impacts on
disease.
The ocean’s marine systems
act as a heat conveyer,
carbon sink, a bank for
genetic diversity and
generates oxygen. In rapid
decline
Tropical savannah systems play
a role in moisture feedback ,
regional rainfall patterns and
act as carbon sinks. They
remain relatively stable.
Implications for European Union
Domestic reductions (~40% below 1990 by 2020) are only part of total EU
obligation. The rest would have to be met internationally.
