I have data(in excel) for atmospheric CO2 in Antarctic from 1994-2009.
I used the very basic way to plot the time series, and now I want to predict the CO2 ration , maybe for 5 years.
please help.
clear all;
datas = xlsread('atmos.xlsx');
x = datetime(datas(:,1), 'ConvertFrom', 'Excel', 'Format', 'MM.yyyy');
y = datas(:,2);
plot(x,y)
excel data sheet is atatched.

Do you have the Statistic and Machine Learning Toolbox? If so then you could fit a simple linear model to your data like this:
mdl = fitlm(days(x-x(1)),y)
You could also fit a more complicated model, perhaps with seasonality, but let's start there.
