Unfortunately there is no differentiation between natural and anthropogenic causes, and the extent of each of these factors, on these phenomenon to make any real sense of what is occurring.

So for the tourist, planning a holiday to destinations with predictable weather and no impending natural disasters is going to become more difficult!

Catherine, we need more research!

Thank you. We would love some of Southern California’s sunshine – or Australia’s or anywhere’s. The UK Met Office has been publishing notes on climate change predictions for these countries and for the UK. Here is what the UK is in for:

Climate change projections for the UK
For the A1B emissions scenario the UK is projected to experience temperature
increases of up to around 3°C in the south and 2.5°C further north. The agreement
between models is moderate in the south of the UK and low further north.
Europe shows a strong contrast in projected precipitation changes, with large
decreases in the south and large increases in the north. The UK falls towards the
northern region with generally increasing precipitation, with projected increases of up
to 10%, though some southern parts of the UK may experience decreases of up to
5%. There is generally good agreement between ensemble members over the north
of UK, but moderate agreement further south, indicating uncertainty in the position of
the transition zone between increasing and decreasing precipitation over Europe.
HOWEVER though the Met Office is pretty good at predicting the next 5 days, they are weak over 10 days and hopeless for longer periods. This time last year they were predicting a drought, which was quickly followed by the longest wettest period on record. We can’t regard this as relevant evidence re long term climate change but it does make one think. I have stopped spraying CFCs into the air to warm things up!

Climate change projections for Australia
•
For the A1B emissions scenario projected temperatu
re increases are larger over
central and western regions of Australia, with chan
ges of up to around 4°C. Along
most of the coastal regions, changes of around 2.5°
C are more typical. There is good
agreement between the CMIP3 models over all of Aust
ralia.
•
For precipitation changes, there is moderate to lo
w agreement amongst the CMIP3
ensemble of models. Decreases of around 20% or mor
e are projected over some
parts of the far west, but moderate decreases of ar
ound 5% are more typical over
most of Western Australia, as well as eastern Queen
sland, Victoria, and southern
South Australia. Much of the Northern Territory, Q
ueensland, and parts of New
South Wales are projected to experience increases o
f up to 5%, with increases of up to 10% in the far north.

Yes – we are doing it by trying to keep warm!

Thank you both.
