subject: Things you should know about climate change [print this page] Heavier rainfall is causing flooding in some areas, while there is extreme drought in others, resulting in famine. The first half of the twentieth century was not unusual: The period of 1900 to 1939 brought mild winters, characteristic of a high North Atlantic Oscillation (NAO) condition. However, in the 1950s, the global average temperature fell, and some thought an ice age was imminent. Then, the NAO suddenly flipped to high, and some scientists declared that the warming was a permanent phenomenon because of humans promiscuous use of fossil fuels. If so, the likelihood of famine remains a constant.
