By Tom Hafer and Henry I. Miller Floods, droughts, hurricanes, tornados are all said to be worsened by global warming, which is currently at nearly 1.5 degrees Celsius above pre-industrial times. This may not sound like much but consider that 20,000 years ago the temperature was only 8 or 9 degrees C lower than now and that gave rise to an ice age with most of North America covered by a giant glacier. That illustrates that a few degrees of temperature change can have dramatic effects.
