Turning the World into a Desert
Fr. Sean McDonagh, SSC (February 6th 2009)
For months the media has been saturated with stories about the economic downturn, lack of confidence in the banking system and rising unemployment. The language used by journalists and commentators has become increasingly shrill, with words like ‘catastrophe’ and ‘unprecedented’ appearing regularly. Everything else, including tackling climate change, seems to have been put on the back-burner. Such a course of action would be truly disastrous because climate change will continue to take its toll on people and the environment if radical measures are not taken now to move away from a global carbon-based economy.
Most people are aware that increases in the frequency and power of hurricanes and typhoons can be attributed to climate change. The devastating scenes from New Orleans after it had been struck by hurricane Katrina are still vivid in people’s minds. Few people are aware that climate change will cause severe droughts in many parts of the world and turn fertile lands in deserts..
In 2006, Eleanor Burke and her colleague at the Met Office’s Hadley Centre for Climate Prediction and Research in Britain wrote that one third of the planet will be desert by 2100 if climate change is not addressed urgently. They used a measure called Palmer Drought Severity Index (PDSI) to predict where moderate to severe droughts will happen. The PDSI figures for moderate droughts at the moment are 25% of the Earth’s land surface. The study found that this will increase to 50% by the end of this century. The findings for severe droughts are even more alarming. These will jump from a current 8% to 40%, and extreme droughts, which affect 3% of the Earth today, will affect 30% of the earth within 100 years. The authors of the report admitted that there are “uncertainties” with their predictions since they only used one climate change model and one future scenario of greenhouse gas emission which is in the moderate-to-severe range. Nevertheless, the head of the Hadley Centre’s climate programme, Vicky Pope, said that the findings were significant.[1]
Africa immediately comes to mind when we think of droughts. There have been crippling droughts in east Africa. Kenya’s Rift Valley has experienced droughts though-out this decade, which left cattle and other animals dead from lack of food and water and humans malnourished and hungry. In 2006, 11 million people in Ethiopia, Eritrea, Somalia and Tanzania were affected by drought.
It is not only poor countries in Africa which are in danger of having more prolonged droughts. In early February 2009, Steven Chu, the Nobel laureate who has been appointed Secretary of Energy by President Barack Obama, told the Los Angeles Times, that California’s agriculture could be reduced to a dust bowl and its cities disappear unless there is timely action on climate change. [2] Chu pointed out that the warming has caused a marked decline in the Sierra mountains snow-pack. These snow capped mountains act as a natural storage system for water for both agriculture and human consumption. Chu predicted that unless global warming is contained there could be a 90% reduction in the Sierra snow-pack. This would mean disaster for California.
But even this year water is a problem. Bill Diedrich, who is a fourth generation almond grower in California’s Central Valley, expects that many of his trees will not survive the drought. “It is one of the grimmest water situations we’ve ever faced,” he said. It’s an absolute emergency and anything to get the water flowing quickly is needed.”[3] Lester Snow, director of the California Department of Water Resources told reporters that the state faces its most severe drought since the early 1990s. The Central Valley in California, stretching 400 miles, is the world’s largest agricultural area. Half of the salads and vegetables consumed in the U.S. are grown there. Huge areas are covered with almond trees. |If this rich farm-land is lost to agriculture, as Secretary Chu fears, this will be a catastrophe for the U.S. and the World.
Chu is alarmed because he does not think that “the American public has gripped in its gut what could happen (through climate change).” How could they after 8 years of denial that climate change was happening by the administration of former President George W. Bush, He was not alone: A whole swathe of U.S. industries, especially in the petrochemical ones, through the Carbon Club television advertisements, bombarded the American people with anti-climate change propaganda through-out the 1900s? In 2008, Exxon was still bankrolling climate sceptics.
