Don't Wait for Too Little Too Late: Ideas for now to stop climate change

A short list of relatively simple actions taken to reduce greenhouse gases other than CO2 could help put the brakes on global warming.
The 14 measures that would immediately slow global warming are:

—Eliminate methane releases from coal mines—particularly in China—by capturing it and burning it.
—Eliminate the venting or accidental release of methane co-produced by oil drilling (and, of course, gas drilling itself), particularly in Africa, the Middle East and Russia.
—Capture gas from landfills in the U.S. and China as well as promote recycling and composting of biodegradable trash.
—Occasionally aerate flooded rice paddies to prevent the growth of methane-producing microbes.
—Stop leaks from natural gas pipelines, particularly in Russia.
—Use bio-digesters—vessels in which microbes break down manure into gas—to cut methane from livestock globally.
—Update wastewater treatment plants to capture methane.
—Filter the soot produced by incomplete combustion of diesel fuel in vehicles, and attempt to eliminate inefficient internal combustion engine vehicles entirely.
—Replace indoor cooking and heating fires with clean-burning cookstoves fired either by wood, manure or other biomass or, even better, methane.
—Replace traditional brick kilns with more advanced firing methods.
—Replace traditional ovens for turning coal to coke with modern technologies.
—Ban the open burning of crop stubble and other agricultural waste.

The researchers estimate that cutting those 14 together could avoid between 700,000 and 4.7 million premature deaths (largely from smoky, unhealthy air) and increase crop yields by between 30 million and 135 million metric tons (due to concomitant reductions in ground-level ozone, otherwise known as smog, which forms from fugitive methane and blights crops in Brazil, China, India, the U.S. and elsewhere). In addition, the economic analysis suggests that many of these measures provide more value in benefits than they cost to implement.
