Find a point on a graph

Hi,

I am extrapolating a line of best fit to find what increase in co2 will cause an increase in temperature of 2 degrees. Is there a scientific way I can work out what x value (co2 concentration) relates to the y value (temperature) on Matlab?

Thanks

You need to form a model, that FITS the curve. Choose something that makes sense in context. (Is that relation truly linear?) Fit the curve to the data. Then solve.

If it’s a linear relationship (as this article suggests), rearrange the typical ‘T=m*[CO2]+b’ relationship to get: ‘[CO2]=(T-b)/m’.

You need to do a DuckDuckGo search. When I did, I found a number of articles. In ‘Carbon Emissions Linked To Global Warming In Simple Linear Relationship’, they state: ‘These findings mean that we can now say: if you emit that tonne of carbon dioxide, it will lead to 0.0000000000015 degrees of global temperature change.’

Global warming is real.
