Richard Smith writes: Since the 1990s, climate scientists have been telling us that unless we suppress the rise of carbon dioxide emissions, we run the risk of crossing critical tipping points that could unleash runaway global warming, and precipitate the collapse of civilization and perhaps even our own extinction. To suppress those growing emissions, climate scientists and the UN Intergovernmental Panel on Climate Change (IPCC) have called on industrialized nations to slash their carbon dioxide emissions by 80 to 90 percent by 2050.
But instead of falling, carbon dioxide emissions have been soaring, even accelerating, breaking records year after year. In May 2013, carbon dioxide concentrations topped the 400 parts per million mark prompting climate scientists to warn that we’re “running out of time,” that we face a “climate emergency” and that unless we take “radical measures” to suppress emissions very soon, we’re headed for a 4-degree or even 6-degree Celsius rise before the end of the century. And not just climate scientists have made warnings, but also mainstream authorities, including the World Bank, the International Energy Agency (IEA) and others. In 2012, the IEA warned that “no more than one-third of proven reserves of fossil fuels can be consumed prior to 2050 if we hope to prevent global warming from exceeding more than 2 degrees Centigrade.” In September 2014, the global accounting and consulting giant PricewaterhouseCoopers warned that:
For the sixth year running, the global economy has missed the decarbonisation target needed to limit global warming to 2˚C . . . To avoid two degrees of warming, the global economy now needs to decarbonise at 6.2 percent a year, more than five times faster than the current rate, every year from now till 2100. On our current burn rate we blow our carbon budget by 2034, sixty-six years ahead of schedule. This trajectory, based on IPCC data, takes us to four degrees of warming by the end of the century.
Yet despite ever more dire warnings from the most conservative scientific, economic and institutional authorities, and despite record heat and drought, superstorms and floods, and melting ice caps and vanishing glaciers, “business as usual” prevails. Worse, every government on the planet is pulling out all the stops to maximize growth and consumption in the effort to hold on to the fragile recovery. [Continue reading…]
