The ‘Bottom Line’ - what we need to deliver
Enhanced resilience of our
infrastructure, communities and
business and natural environment to
climate change
Reductions in Greenhouse Gas
(GHG) emissions of 80% - by 2050
Opportunities for competitive
advantage and economic
diversification realised
What can we expect in the
North East?
Changing weather patterns
Warmer, wetter winters
Hotter, drier summers
Reduction in soil moisture in summer
Increase in ‘high intensity’ rainfall events
Polarisation of rainfall
Higher incidence and severity of storm events
Changes is biodiversity
Changing patterns of public usage – natural environment
Resolution…
Issues…
Does not consider:
• Altitude
• Topography
• Proximity to coast etc
Gives:
• Broad, generic data –
• Warmer, wetter winters
• Hotter, drier summers

Earwig modelling…
Does consider:
• Altitude
• Topography
• Proximity to coast etc
Gives: (caveat)
• High resolution
• Considerably more detailed
• Allows understanding of
impacts at a level that
enables ACTION
Why choose the 2050s?
Climate change is already happening
Stopping GHGs today will not prevent it
CC over next 30-50 yrs due to historic emissions
Within long-term planning horizons

A Few Key Messages……………..

Observation and measurement confirms that the
worst case IPCC scenarios, or worse, are being
realised.

It would appear likely that there is less than a 50%
chance that we can restrict warming to less than 2
degrees.
More detailed understanding of natural processes
indicate that current projections of sea level rise are
inadequate and may be significantly underestimated
Sea level rise may well exceed one meter by 2100 if
emissions remain unabated
Long term sea level rise over several centuries is
likely to be several meters, consistent with
paleoclimate data
“There is no excuse for inaction”
We’re getting the data – we need to use it (wisely!)
"I was pleased to see the strength of the Climate Change Partnership in
the North East, particularly the quality of the North East Adaptation Study.
"The study tells us what we need to do to adapt in the face of dangerous
climate change. This work and the commitment from many groups and
sectors, including local government in the North, is very encouraging."
Rt Hon. Hilary Benn, Secretary of State for the Environment
“We are already seeing in the North East the thinking, action and sense
of purpose to deliver real progress on fighting climate change”.
Joan Ruddock, Department of Energy and Climate Change Minister, 2009
