Last 4 marker this is as far as I got.
Sun is emitted as short wave radiation. It is absorbed as long wave infra red radiation. This is then absorbed by greenhouse gases, causing the earth to warm and the greenhouse effects. Things such as ice clads melting and a disruption in migration patterns are a result of this.

I’m so annoyed about the first calculation because I got 31 but then I thought it was at too big so I put 0.31 instead but hopefully they see that I did do 31 in the first place 🤣🤣

Well I got a decimal don’t remember the exact number though. Because I think it was the number they gave per dm3 divided by 4 as it was 250cm3

Oh and also it gave it as mg per dm3 so the mg had to be divided by 1000 as it wanted the answer in grams, giving the decimal. I’m hoping the 0.31 answer is the right one lol
