But rising temperatures in this time have acted as a handbrake to farming productivity of crops and livestock, according to the new research, published in Nature Climate Change. Productivity has actually slumped by 21% since 1961, compared to if the world hadn’t been subjected to human-induced heating.
Our baseline model indicates that ACC has reduced global agricultural TFP by about 21% since 1961, a slowdown that is equivalent to losing the last 7 years of productivity growth.
Right, so, the heating has lost us 12% of the gains we should have had from the use of artificial fertilisers, which are themselves a leading cause (no, really) of the heating. So, we gain 88%, lose 12%. That’s a win, right?
