The possibility of an abrupt shift in the climate system is only one feature of a changing climate that is expected to become more erratic, with extreme weather events like droughts, torrential rainfall, and extreme heat becoming more common.
Can sudden climate change?
Most abrupt climate shifts are likely due to sudden circulation shifts, analogous to a flood cutting a new river channel. The best-known examples are the several dozen shutdowns of the North Atlantic Ocean’s Meridional Overturning Circulation during the last ice age, affecting climate worldwide.
What can cause abrupt climate change?
Abrupt climate change can occur when the Earth system gets pushed across a threshold, whether by some sudden event like a massive volcanic eruption or by the accumulation of more gradual forces, or “forcings” on the system.
Does climate change tend to be more abrupt or gradual?

What happens if AMOC shuts down?
The timeline of a potential collapse of the AMOC remains unclear, but the consequences for the Earth’s climate would be immense. Temperatures in Europe and the east of North America would drop by as much as 5 degrees Celsius (9 degrees Fahrenheit), leading to more extreme winter weather.
Can sudden change in weather cause allergies?
Yes, absolutely. Just as the change of seasons and the gradual changes in weather that follow can cause allergies to flare up, so can isolated weather events, like wind and rain. Dry, windy days: Gusts of wind can blow pollen and other allergens into the air, causing hay fever and other reactions.
What could cause a sudden ice age?

How many natural abrupt climate change events occurred in the last 110000 years?
During the past 110,000 years, there have been at least 20 such abrupt climate changes. Only one period of stable climate has existed during the past 110,000 years–the 11,000 years of modern climate (the “Holocene” era).
Is deforestation a sudden change?
The problem is that while deforestation is sudden, complete, and easy to spot when comparing satellite images from one year to the next, forest regrowth is slow, incremental, and much harder to identify from year to year.
What is the effect of rapid climate change?
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
Is deforestation causing a sudden change?
Deforestation causes increases in temperatures and changes in the amount and distribution of rainfall —generally creating a drier climate. These impacts can affect soil moisture, reducing yields in some areas and increasing flooding in others.
