methane emissions

Atmospheric methane, From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Atmospheric_methane#Emissions_accounting_of_methane

"... it (methane) traps 29 times more heat per mass unit than carbon dioxide ... "


Mass (Tg/a) Type (%/a) Total (%/a)
Natural Emissions
Wetlands (incl. Rice agriculture) 225 83 37
Termites 20 7 3
Ocean 15 6 3
Hydrates 10 4 2
Natural Total 270 100 45


Anthropogenic Emissions

Energy 110 33 18
Landfills 40 12 7
Ruminants (Livestock) 115 35 19
Waste treatment 25 8 4
Biomass burning 40 12 7
Anthropogenic Total 330 100 55

Sinks
Soils -30 -5 -5
Tropospheric OH -510 -88 -85
Stratospheric loss -40 -7 -7

Hi Steven,

It does appear this is an old fact sheet. The most up to date methane emission numbers can be found in this blog:

EPA Draft Says Oil & Gas Methane Emissions Are 27 Percent Higher than Earlier Estimates by David Lyons

Methane Leaks by Environmental Defense Fund

Reference: Methane leakage from natural gas operations

Title: stevenlevymath: UN "Livestock's Long Shadow", Executive Summary Illustrations
Description: Easy to understand pie charts, animated drawing
Tags: math, agriculture, climate change, livestock, methane, UN
Content Area : Mathematics | Subject : Grade 6 | Category : Ratios & Proportional Relationships | Skill : RP.6.3.c
=========================================
Production Notes:
Dec.24, 2015: Using Audacity I "fixed" the sound. Here are the steps: First "Noise Removal".
Apply "normalization."
"Equalization", AM Radio profile, use flatten
"Compression". Make softer louder. and Louder softer.
"Normalize again".
