Fire can change the climate quickly with large emissions of CO2 and other pollutants such as black carbon

Wednesday, February 24th, 2010

These warnings come from an international team of fire specialists from six nations. One of them, Thomas Swetnam of the University of Arizona in Tucson said “We’ll be seeing more and longer droughts, and with more hot and dry years, we’ll be seeing still more and larger fires.” California’s fire in 2008 wiped out 380,310 acres. In 2009, California is dealing with their 3rd year of serious drought.

Wild fires aggravated by global warming further speed up climate change

Wednesday, February 24th, 2010

Scientists at a geosciences conference in Vienna predict fires will increase and could spread to previously fire-free parts of the world as the climate changes, and in turn contribute to global warming by producing greenhouse gases. In 2007, more than 200 wild fires erupted in Southeastern Europe. Canadian fires are expected to double with a longer fire season by the end of century.

The effects of climate change exacerbated the ferocity of 2009 forest fires in Australia

Wednesday, February 24th, 2010

Eucalyptus forest and farms in south-eastern Australia are getting warmer, drier and more prone to fire due to global warming. Tens of thousands of wildfires blaze every season, with climate change exacerbating their intensity.

Climate change could wipe out 85% of Amazon rainforest by 2150

Wednesday, February 24th, 2010

According to a study by UK Met Office Hadley Centre published in Nature Geoscience, a rise of just 1 degree could have irreversible impacts on the forest; 75% forest loss for a 3 degrees rise, and 85% for a rise of 4 degrees.

Fire’s effect on ecosystems and climate change was previously underestimated

Wednesday, February 17th, 2010

A new report shows that all fires combined release an amount of carbon dioxide into the atmosphere equal to 50 percent of that coming from the combustion of fossil fuels. “It’s very clear that fire is a primary catalyst of global climate change,” said Swetnam, director of UA’s Laboratory of Tree-Ring Research. Huge areas of boreal forests of Siberia, Canada and northern Europe burn each year.

1kg of beef requires 15,000 litres of water – and other facts from Economist

Wednesday, April 8th, 2009
  • California Governor Arnold Schwarzenegger might issue water rationing in the state to avoid a water crisis.
  • Brazil and South Africa depend on hydroelectric energy, but do not have enough water to power their turbines.
  • Australia is suffering a 10-year drought.
  • Farmers use three quarters of the world’s water.
  • 1 kg of wheat requires 1,000 litres of water, 1 kg of beef requires 15,000 litres of water.
  • The American and European diet requires 5,000 litres of water a day while the predominately vegetarian diets in Africa and Asia use only 2,000 litres.

Drought could turn tropical forests from carbon sinks to net carbon emitters

Thursday, March 5th, 2009

Tropical forests like the Amazon, if they do not receive enough rainfall, emit tonnes of carbon dioxide.

The severe 2005 drought in the Amazon triggered by the warming of the North Atlantic released 5 billion tons of carbon dioxide. 100 millimetres (4 inches) of water deficit could trigger a loss of 2.7 tons of aboveground forest carbon per hectare.

Droughts also increase the risk of fires and threaten biodiversity.
