Ok, actually quite a few scientists believe that abrupt climate change can occur and has happened in the past in less than a decade. It has been noted
than in past ice ages (not Ice Age, which is longer and happens over a longer period of time) the changes started happening in a decade and abrupt
changes have, and can, happen within a few years. Let me quote this again.
" While ice ages that come on over tens of thousands of years have periodically covered large areas of the globe with glaciers, Alley is more
concerned with rapid climate changes -- within a decade -- that effect the northern and southern hemispheres differently. "The secret of why the
whole world rides a roller coaster in the ice age and freezes and thaws is probably greenhouse gases, especially carbon dioxide," Alley told
attendees today (Feb. 17) at the annual meeting of the American Association for the Advancement of Science. "The seesaw effect of rapid climate
change is probably caused by ocean circulation and the keys to this change are locked in the polar ice." "
".......Earth’s climate repeatedly has shifted abruptly and dramatically in the past, and is capable of doing so in the future.
Fossil evidence clearly demonstrates that Earth vs climate can shift gears within a decade, establishing new and different patterns that can persist
for decades to centuries. In addition, these climate shifts do not necessarily have universal, global effects. They can generate a counterintuitive
scenario: Even as the earth as a whole continues to warm gradually, large regions may experience a precipitous and disruptive shift into colder
This new paradigm of abrupt climate change has been well established over the last decade by research of ocean, earth and atmosphere scientists at
many institutions worldwide. But the concept remains little known and scarcely appreciated in the wider community of scientists, economists, policy
makers, and world political and business leaders. Thus, world leaders may be planning for climate scenarios of global warming that are opposite to
what might actually occur. "
" The climate record for the past 100,000 years clearly indicates that the climate system has undergone periodic—and often extreme—shifts,
sometimes in as little as a decade or less.
The causes of abrupt climate changes have not been clearly established, but the triggering of events
is likely to be the result of multiple natural processes. "
