For corn, small long - term average temperature increases will shorten the duration of reproductive development, leading to yield declines, 4 even when offset by carbon dioxide (CO2) stimulation.5, 6 For soybeans, yields have a two in three chance of increasing early in this century due to CO2 fertilization, but these increases are projected to be offset later in the century by higher temperature stress7 (see Figure 18.2 for projections of increases in the frost - free season length and the number of summer days with temperatures over 95 °F).
Assuming we still don't reform our ways, the 40 years after 2040 could then see another sharp 2 degree increase in temperatures — to 4 degrees Celsius — and another dramatic surge in sea level, culminating in a rise of 2 feet averaged across the globe, or more if we're unlucky.
«It seems clear that climate change is happening, we continually have record temperatures for the time of year, there is no return of temperatures to «below average» which we would expect if this was just statistical variation, there is increasing turmoil in the weather, the barrier reef is bleaching to an extent not seen before and so on.»

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

It will always come back to the fact that, nominally, it's all about the Sun — e.g., Farmers Almanac is predicting another cold wet winter despite the increase over the years in the amount of atmospheric CO2: No region will see prolonged spells of above - normal temperatures; only near the West and East Coasts will temperatures average close to normal.

As Judith says, one of the key conclusions is the paragraph in large red letters «Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations... Discernible human influences now extend to other aspects of climate, including ocean warming, continental - average temperatures, temperature extremes and wind patterns (see Figure SPM.4 and Table SPM.2).»
