Transit that uses renewable energy, or zero fossil fuels. Such as walking & cycling. Obviously one can cut beef out of their diet, or go full vegetarian. Stop flying is a bit trickier for people who need to travel around, but high speed trains that run on electricity are a good consideration.

And a lot of travelling can be replaced with video meetings. (Seriously, what is a good term? I was about to write Skype-meetings, but want a general term (in particularly since Skype predictably sucks more and more since MS bought them).)

Video calls, remote meetings, typically how we call it at work. Use it with clients even in the city

Stop pumping carbon into the sky?

Have you seen a volcano erupt in real-time via satellite? I have and I've tracked the plume for days and sometimes weeks. Sometimes, there are 5 or 6 of these events a day. A very rare day to not have at least one of earth's visible volcanoes erupt.

Now lets talk about all the volcanoes that are underwater... then we can talk about solar weather and more...

Nobody is impressed by your stupid stories of having been a weatherman in the air-army. Annual average volcano emissions are three orders of magnitude smaller (that's 1/1000, for the innumerate in the audience) than human CO2 emissions from fossil fuel combustion. And you can't fucking _see_ CO2 anyway. It's fucking invisible. Whatever you saw from that volcano was water or dust or ash or whatever, the things that volcanoes spew into the upper atmosphere that counteract the warming effect of their CO2 emissions.

Your tone greatly diminishes the value of your arguments (on which I agree, by the way). Could yo try being less personally aggressive, next time?

No. This is the tone I intend to take with all dimwitted or disingenuous climate change deniers on this site.

Even cutting down on beef while still eating other meat would be a significant help, I believe. That's achievable though I imagine the beef industry would lobby against any push.
