What's more, his company continues to flourish, still producing animated and live-action films and overseeing the still- growing empire started by one man: Walt Disney, who will never be forgotten.
25 times. Methane GWP potency compared to carbon dioxide over a 100 year period. âMethane is a relatively potent greenhouse gas. Compared with carbon dioxide, it has a high global warming potential of 72 (calculated over a period of 20 years) or 25 (for a time period of 100 years).3 times. Methane has about 23 times the global warming potential of carbon dioxide when it is released into the atmosphere. âMethane (CH4) . . . is the simplest hydrocarbon, and is the primary component of the natural gas that we burn for energy.
Carbon dioxide is the main one, because the atmosphere holds 200 times as much of it. But a given amount of methane traps at least 25 times as much heatâunless you burn it first. Then it enters the atmosphere as COâ. Thatâs the other side of this Jekyll-and-Hyde story: A lot of methane is being burned these days. In the past decade the technology called hydraulic fracturing, âfrackingâ for short, has enabled drillers in the United States to extract natural gas from deeply buried shales they couldnât tap before.
