That’s insane . It matters a lot. Climate Affects evolution. If we weren’t around it was for a good reason. The only relevant time frame is the length of time man has been on earth. Now, when do you say man first appeared ?
I first appeared in 1961 ... my father in 1925 ... his father in 1889 ... climate hasn't change in that short of a time period ...
I'll be driving south this weekend to do grocery shopping ... takes me about two hours and the temperature will be 2ºC warmer ... I survive this trip every month for three years now ... just curious, how much do you think average temperatures will be rising in the next 100 years? ... the IPCC isn't always correct and perhaps you have better information than they do ...
∆T = 5.35 k ln (CO
2F/CO
2I)
where ∆T = change in temperature, k = climate sensitivity, CO2F = final carbon dioxide concentration, CO2I = initial carbon dioxide concentration ...
Are you familiar with the behavior of logrithmic functions?
