In order to work out what kind of action should be taken on global warming, theUnited Nations Intergovernmental Panel on Climate Change (IPCC), created aforecast on what the climate conditions will be like by the end of the century. This
forecast was called the Special Report on Emissions Scenarios (SRES).
SRES Temperature forecasts
Case Temperature increase Temperature increase
Best estimate to 2100 Likely range to 2100
B1 scenario +1.8 +1.1 – 2.9A1T scenario +2.4 +1.4 – 3.8
B2 scenario +2.4 +1.4 – 3.8
A1B scenario +2.8 +1.7 – 4.4
A2 scenario +3.4 +2.0 – 5.4A1FI scenario +4.0 +2.4 – 6.4

ROME - Climate change is making forest fires around the world
bigger and more intense, increasing the threat to people and the
environment and costing countries millions in damage and
firefighting expenses, the United Nations reports.
FAO global assessment of forest fires-2005
Mediterranean countries also said that warmer temperatures andreduced rainfall in summer — both associated with climate change —would increase the risk of fires in the region and beyond.

North American researchers reported that the incidence
and severity of fires "will increase dramatically" with globalwarming.

Over the past several decades, the area of Canadian borealforest affected by fire and insects has doubled. Although there arecomplex factors involved, the greatest increases so far have been inthe regions of greatest warming. Continued warming will produce
greater seasonal contrasts which, combined with an expected 44%
increase in lightning strikes, is expected to increase the area burnedby 78% in the next 50 years.

Fire regimes are determined by four factors: intensity (how severe
fires are), frequency (how often fires occur), season (the time of the year firesoccur) and scale (how extensive each fire is and the patchiness of the burnt
and unburnt mosaic).

“Professor Balzter said "Last century a typical forest in Siberia hadabout 100 years after a fire to recover before it burned again. Butnew observations by Russian scientist Dr Kharuk have shown thatfire now returns more frequently, about every 65 years. At the same
time annual temperatures in Siberia have risen by almost twodegrees Celsius, about twice as fast as the global average. Andsince 1990 the warming of Siberia has become even faster thanbefore." “
