Yes it is is kike bullshit. The catalytic converters won't work properly until they hit their operating temperature, but the "harmful pollutants" they release is negligible unless you're running your car in a closed garage. The jews and their shabbos goyim flying all over the world in their private jets to gather at climate change meetings that tell us we're the problem don't give a shit about the environment. It's just about jew control over the goyim.
Thinking about this just now, I'm surprised they haven't tried to tell us climate change is happening because of the 6 gorrillion jews and muh holohoax. I bet if I search that I'll find some article written by a (((journalist))) that says that. Fucking jews.
A cold engine will produce soot the same way holding a spoon in a candle flame causes it to be covered in soot. The cold cylinder wall cools the air-fuel mixture before it fully combusts. That cylinder is kept far too cold by the very cold oil. Until the engine reaches operating temperature the engine is not running as clean or efficient as it can.
But you are right not to trust the jews.
Cars today now have pre-cats for the cold starts. But it's a good idea to not rev your cold engine, let the car do it's warm up start on its own.
This is also good reason to have a large displacement engine, for winter. Below 0, it gets hard for small engines to put out enough heat for the interior.
