That's true, very acute.Just like everyone else...
So is global climate change man made and what evidence is there for it? Another question is what are the consequences of humans pumping carbon into the atmosphere since the 1850’s?One of those people I see! Shouldn’t you be over on the Prius forum?
There is no “trend”, only a cycle which we’ve not lived through or documented before. We don’t control or change climate by the vehicles we drive or type of fuel that we burn. Air quality, yes, we contribute heavily to that, but temperature of the globe, nope.
“https://climate.nasa.gov/evidence/“ said:Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
There is a scientific consensus (over 97% of actively publishing climate scientists. Source: https://scienceexchange.caltech.edu) and evidence that global climate change is man made.“https://climate.nasa.gov/evidence/“ said:Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming. Carbon dioxide from human activity is increasing more than 250 times faster than it did from natural sources after the last Ice Age.

Short list of negative, observed, environmental effects:“https://climate.nasa.gov/evidence/“ said:The current warming trend is of particular significance because it is unequivocally the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over millennia. (Reference: 1) It is undeniable that human activities have warmed the atmosphere, ocean, and land and that widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.
Love Tony.Something I found.. I will add That I dont care either way.

FYI diesels doesn't create brown smog. And the largest contributor of Nox is marshland, which environmental agencies in California are reintroducing million of acres of throughout the Bay Area, highly populated area btw. Actually London experienced the greatest threat of smog ever during the Great Smog of 1952. What cleaned up that air quality since? Oh unregulated diesels. lol The level of EnviroPropaganda regurgitated on the internet is sad.Whooooooo boy one of these threads. Even as an actual scientist in a climate-adjacent field, I'm not going to chime in on the climate banter because no one's opinions will be swayed by an internet forum about issues that have social or political implications.
What I can share is this: diesel emission reductions are focused on removing NOx and particulates, both of which correlate much more strongly with near-surface smog than the global carbon cycle. In other words, the climate debate on this thread is irrelevant because the DPF and the SCR on these trucks are there solely to keep the air in populated areas from turning brown, particularly in winter.
