Climate Disruption

What does it mean for wildfire and ecosystems?Should we care?

Can we do anything?

Amplified Warming6 Increased levels of GHGs trap

more infrared energy and heatthe atmosphere and the earth

Natural Warming1 Sunlight energy heats the earth2 Heat is radiated out (infrared energy)3 Radiated energy is absorbed by GHGs and re-radiated4 Some infrared from GHGs further warms the earth5 Remaining infrared is emitted to space

Weather and Climate

l Weatherq Day-to-day variation in temperature,

precipitation, humidity, wind and atmospheric pressure – the state of the atmosphere at a particular time

8

World Climatesl Climateq Averages or extremes of temperature,

precipitation and other atmospheric variables over longer periods of time (months, years, decades, centuries)

Weather and Climate Variability

Climate Variability

Short term: (years todecadal) rises andfalls about the trendline (ENSO)

Climate Oscillations

Multi-decadal oscillations in regional climate (e.g. PDO, NAO)

Climate ChangeLong-term trends or major shifts in climate (mulit-decadal to century-scale)

18NASA/Goddard Space Flight Center – MERRA Dataset (June 1- July 8, 1988)

It is theorized that the loss ofarctic ice due to increasing temperatures is slowing the

eastward flow and increasing the amplitude of the jet stream

Alteration of the jet streampotentially increases the intensity

and duration of extreme eventssuch as droughts and severe storms

(cold polar air drawn southand warm air drawn north)

Note that the projected annual temperature shifts far exceed historical variability (20th century), while the projected precipitation shifts do not.
