climate change

• Is a gradual increase in the overall temperature in the Earth's atmosphere generally attributed to the greenhouse effect
• The greenhouse effect happens when certain gases, known as geenhouse gases collect in the earth's atmosphere

Climate change

• (caused by) these gases can occur naturally in the atmoshpere including carbon, dioxide, methane, nitrogen dioxide, and flourinated gases known as Cholorofluorocarbons

climate change

• since the industrial revolution in the early 1700s late 1800s people have been releasing large quzntities of greenhouse gases into the atmoshpere

causes of climate change/habitat damage

• agriculture
• land conversion for development
• water development
• pollution
• greenhouse gases

Effects of climate change

• tHE MOST OBVIOUS EFFECT IS THAT GLACIERS AND ICE CAPS MELT FASTER THAN USUAL
• the MELT WATER DRAINS INTO THE OCEAN CAUSING SEA LEVELS TO RISE AND OCEANS TO BECOME LESS SALTY
• patterns in precipitation( rain and snow) may change or become more extreme
• the speed at which global warming is taking place is unprecedented; so all the effects are unknown

examples of climate change

• warmer springs have led to earlier nesting for 28 migratory birds species on the east coast of the us
• Northeastern birds that winter in the southern us are returning north in the spring 13 days earlier than they did in the 20th century
• (in a california study) 16 out of 23 butterfly species shifted their migration timing and arrived earlier

food web disruptions

• The impact of climate change on a specific species can ripple through a food web and affect a wide range of other organsims
• EX. Declines in the duration and extent of sea ice in the artic leads to declines in the abundance of ice algae, which thrive in nutrient-rich pockets in the ice
• Those algae are eaten by zoo-plankton, which are eaten by Arctic cod, an important food source for many marine mammals like seal. and seals are eaten by polar bears
• hence, declines in ice algae can lead to declines in polar bear populations

food web disruptions

• pockets in the ice
• those algae are eaten by zooplankton, which are eaten by arctic cod, an important food source for many marine animals like seal. and seal are eaten by polar bears

food web disruptions

• Hence declines in ice algae can lead to declibnes in polar bear populatiobns

habitats close to extinction

• coral reefs
• praire potholes
• mangroves
• western/southern forests
• sagebrush steppe

animals close to extinction

• The american pika
• polar bears
• water fowl
• ringed seals
• blue crabs
• lake sturgeon
• walleye
• moose
