Controlling emissions worldwide
The “grim” part of “Planet Earth’s grim check-up” [editorial, July 22] is the not yet fated future. Developed nations have embraced policies to hold the temperature rise to 3.6 degrees Fahrenheit and have begun actions mandated by this limit. But undeveloped nations do not have the technology, resources or, in some cases, the will to give up cheap and available fossil fuels.
To bring undeveloped nations on board with the effort to control greenhouse gas emissions, it may be necessary for developed nations to provide incentives. This could take the form of an international agreement for developed nations to jointly fund aid to undeveloped ones, similar to the Marshall Plan after World War II, for the reconstruction of Europe. If such support is generous enough that clean-energy systems are made cheaper than those from fossil fuels, the whole world can move together to hold future global warming to a tolerable level. Such a plan would be fair, efficient and necessary if the world is to escape an overheated future.
