For many kinds of disruption, from crop failure caused by drought to sickness and death from heat waves, the main risks are in the extremes, with changes in average conditions representing a climate with altered timing, intensity, and types of extremes.

Observational data, evidence from field experiments, and quantitative modeling are the evidence base of the negative effects of extreme weather events on crop yield: early spring heat waves followed by normal frost events have been shown to decimate Midwest fruit crops; heat waves during flowering, pollination, and grain filling have been shown to significantly reduce corn and wheat yields; more variable and intense spring rainfall has delayed spring planting in some years and can be expected to increase erosion and runoff; and floods have led to crop losses.4, 5,6,7

Based on measurements of ecosystem CO2 flux, radiation absorption by plants, crop yields and a model simulating the terrestrial biosphere, a multinational team of researchers has found that during July and August 2003, 500 million tonnes of carbon escaped from the forests and fields across Europe as a result of extreme heat and drought.

That's why I used the expression «represents a serious potential threat to humanity and our environment» (temperature increase by 2100 of up to 6.4 C, increased droughts, floods, tropical cyclones, heat waves, extreme high sea level plus secondary effects, such as crop failures, spread of vector diseases, loss of drinking water from melting glaciers, etc. all as listed in IPCC AR4).
