An Exxon study done in 1982 focused on global warming by Increasing greenhouse gas (GHG) emissions. Remarkably, thirty-seven years ago Exxon accurately predicted that by 2019, the earth would hit a carbon dioxide concentration of 415 ppm and a temperature increase of almost 1ยฐC (Figure 1).

Perhaps because science is so institutionalized that it has become $cience and some people recognize that. Imagine a scientist having a differing opinion about something without consequences. Also, โscienceโ has been completely wrong plenty of times.
I can remember back in the 70's being told we need to get ready for the next "ice age" :R

โ Another factor is the integrity of the steel pipes and fittings. Depending on the quality of the steel and potential exposure to atomic hydrogen, in principle, embrittlement can accelerate propagation of cracks, reducing the pipelineโs service life by 20 to 50 percent. This is only likely, though, if the pipeline already has fractures and is subjected to dynamic stresses due to fluctuating internal pressure while at the same time being exposed to atomic hydrogen. The confluence of all three factors seems unlikely, however: Under normal operating conditions, there should be little load alternation, and only molecular hydrogen (H2).โ

Not sure what NG pipelines are made of but thereโs the issue of Hydrogen Embrittlement.
Per Wikipedia;
Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting in embrittlement. Hydrogen embrittlement occurs most notably in steels, as well as in iron, nickel, titanium, cobalt, and their alloys. Copper, aluminium, and stainless steels are less susceptible to hydrogen embrittlement.[1][2][3][4]

Actually I've been thinking it's time for me to go. I wouldn't have these conversations with folks like y'all in real life so why bother on the internet? I do wish I could send you some of our deranged politicos.:B
