Global Warming

Two degrees of warming by 2050 'very difficult' to avoid

I'm still a climate change sceptic, however this article suggests that the warming will be very significant and very soon. 2050 is only 38 years away (as was 1974), but what does 2 degrees mean?

Sale Temperatures with and without climate change

If our average temperature for each month increased by 2 degrees this would have quite significant ramifications for our crops. We would be planting our winter crops maybe one week earlier, but they would be maturing one month earlier. June and July would disappear which should reduce any waterlogging problems, however it would increase the importance of getting our crops in on time. Assuming our rainfall stays the same it would give us less in crop rain, due to a shorter growing season. With good fallow management this shouldn't be a problem.

Our summer would start one month earlier and finish one month later. Our summer crop heat units would increase by 40%. This should make sorghum growing much easier, but also alllow us to get maize in one month earlier. Earlier planting of maize matches our rainfall pattern better. With earlier maturing winter crops and a longer summer, it should increase our double crop options.
