Off topic, but what's odd about COVID is that China's manufacturing sector is down as well. Even in absolute terms. It makes me realize there are things out there that I'm obviously not even aware of that cause us to pump all this CO2 into the air.

Or maybe the transportation and power generation sectors pollute far more than what I read and believed?

Or maybe clothing manufacture? Or food?

Who knows? But it's made me really curious about what it is out there that hasn't gone down during COVID? (And not just because I want to make a fast buck. It's genuine curiosity.)

    Global greenhouse gas emissions can also be broken down by the economic activities that lead to their production.[1]
        25% is from electricity and heat production;
        14% from transport;
        6% from residential and commercial buildings;
        21% from industry;
        24% from agriculture, forestry and other land use;
        10% from other energy uses.Source: IPCC (2014);

Weird overlap of people who love bitcoin and reducing power usage.

I name them hipsters.

Ah.

So it is power generation and farming.

That makes sense. Thanks.

So as a species, our big gains against global warming are going to be made by reducing CO2 output from the power generation and food production sectors.

I'm particularly fond of the "ourworldindata" website because they combine a very direct and focused outline of the facts with clear visual graphs and charts. IMHO its impossible to understand the scope and complexity of climate change and greenhouse gas emissions without picturing a lot of charts in your head. This pie chart in particular is a very good starting point:
