Global Warming To Reduce Wheat Yields (According To Models!)

If “Global Warming” is the demon it appears its evil byproducts – heat and CO2 are increasing (massively), not decreasing wheat crops in Australia alone…

What planet do these doomsday “scientists” live on?

Sounds a lot like the planet of computer models, government grants and ideology.

Today’s dose of grant funded junk science!


The potential impact of global temperature change on global crop yield has recently been assessed with different methods. Here we show that grid-based and point-based simulations and statistical regressions (from historic records), without deliberate adaptation or CO2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales. With a 1℃ global temperature increase, global wheat yield is projected to decline between 4.1% and 6.4%. Projected relative temperature impacts from different methods were similar for major wheat producing countries China, India, USA and France, but less so for Russia. Point-based and grid-based simulations, and to some extent the statistical regressions, were consistent in projecting that warmer regions are likely to suffer more yield loss with increasing temperature than cooler regions. By forming a multi-method ensemble, it was possible to quantify ‘method uncertainty’ in…
