Abstract

In March 2007, the EU reaffirmed its commitment
to making its fair contribution to global mean
surface temperatures not exceeding 2 °C above
pre-industrial levels. In line with this, the UK
Government has laid legal foundations for an
emissions cut of 60% by 2050. Whilst 2050
reductions dominate the target-setting agenda,
long-term targets do not have a scientific basis
and are leading to dangerously misguided
policies. If a policy is to be scientifically
credible, it must be informed by an understanding
of cumulative emissions and associated emissions
pathways. This analysis of current UK climate
policy illustrates how following the “correlation
trail” from global temperature thresholds to
national emissions pathways fundamentally
reframes the UK’s targets. Considering cumulative
emissions, carbon cycle feedbacks and the
omission of emissions from international
transport dramatically increases both the scale
and immediacy with which emissions need to be
reduced; for example, within the UK, 6-9% p.a.
reductions beginning as early as 2012. The
implications of this are stark; society can no
longer await the decadal timeframes necessary for
a transition to low-carbon energy supply. If the
2 °C threshold is to maintain any meaningful
currency, industrialised nations have little
option but to radically and urgently curtail
their demand for energy.

More and more of these kinds of eco-restoration (aka re-wilding) projects are critical to mitigating and surviving climate change. In particular, specific measures that would help to protect water supplies (surface, ground, precipitation run-off, etc.) are a crucial first step in any ecosystem in any bio-region…in the case of the riparian zones of the Desert Southwest, that means (among other things) removing the damn cattle and restoring the willows and cottonwoods!

Wyatt and the Cottonwood Tree

Wyatt, the immortal wolf, remembers the Old West.

Wyatt led his pack from the wild lands of the Gila to the
Colorado Plateau, concealed by the tunnels of cottonwood that
formed a thin, green line of life for the arid desert. The shade
of the giant cottonwoods provided relief from the heat of the
day. At night, when the leafy canopy veiled Wyatt’s compass of
stars, he would simply follow the corridor upstream.

These passages were filled with birdsong, and kingfishers
swooped down from the branches, diving underwater after their
prey–a skill Wyatt envied. On hot summer days, when he came
upon one of the many beaver dams, he cooled off in their ponds.
Foxes and squirrels found shelter inside the trees. Every

cottonwood was an oasis.
