Ouch! They’re estimating 131 kt of methane! That’s equivalent to approx 3.93 Megatons of CO2 (in terms of its global warming impact over a century) or roughly equivalent to that of a small country like Iceland or Malta annually.
• About 149,714 short-haul flights, or
• About 37,429 long-haul flights.Weird use of segmented flight lengths as a comparator
From what I read, we can expect a 1 degree increase if we release somewhere in the ballpark of 100 billion tons of CO2. Using those figures, 3.93 megatons is 0.0000393 degrees.
As a point of comparison, humans release roughly 40 gigatons of CO2 per year; 3.93 megatons is 0.0098% of that.
As another point of comparison, around 550 gigatons of CO2 is released (and absorbed) by the planet "naturally". 3.93 megatons is 0.0007% of that.
So we are currently within 20% of what the planet does naturally, which seems not that bad actually.
So in reality, the important thing is we're going from a delta of 0 gigatons of CO2 per year, to a delta of +40 gigatons of CO2 per year.
