Transcript of Climate Change & Mother Earth

photo credit Nasa / Goddard Space Flight Center / Reto Stöckli What is Climate Change? - Warming of the Earth`s surface over a long-term period

- Due to increase of average atmospheric temperature How does it occur? - Burning fossil fuels
-Natural gas

- Clearing of land The Greenhouse Effect - Earth's natural greenhouse effect

- Greenhouse Effect

- Grasshopper Effect Challenges of Climate Change Temperature: heat waves, cold waves, permafrost

Wind: tornadoes, hurricanes

Precipitation: drought, flood, blizzards, rain storms, lightening, heavy fogs Changes Occurring - 30% increase in precipitation is predicted
by the end of the 21st century

- By 2050 there will be an increase in annual precipitation of 55mm in Peterborough

- Sea ice melting; critical for traveling between communities during the winter and hunting

- Summer warming; new insects & diseases

-> Thawing of permafrost Thawing of Permafrost
Will Cause: -Shifting grounds



-Sinking/collapse of the ground

->What else will this effect in Northern communities? Climate Change and its Effects
on Mother Earth Jenny Procunier & Rachel Artuso It will effect... -Buildings
-Increase exposure to disease (new insects)
-Thinner ice or open ice
-More natural disasters; tornadoes, river floods, high seas, hurricanes, wildfires … etc
-Effect agriculture output impacting food security & relying on food imports...$$ Health Issues -Nutrient deficiency

-Increase in diabetes


-Respiratory illness *climate change

->What else? Direct Consequences
linked to the atmosphere: -Run-off

-Stream flow

-Lake levels


-Soil moisture

-Sea levels

-Distribution of permafrost

-Natural ecosystems

-Hydrological cycle Direct Consequences
linked to the environment: -Agriculture
-Waterborne transport

-Hunting & fishing
-Hydroelectric power production
-Human settlement on lakeshores & coasts
-Dam failure
-Reduced wetlands & marsh-Lake & stream temperatures change Definitions -Bearing capacity: the ability of a system to absorb impact without taking any preventative action ex: insurance

-Modifying Capacity: action taken to minimize losses my modifying events at the outset ex: cloud seeding

-Preventative capacity: devices that promote actions to reduce vulnerabilities to climate change, and later reduce the impacts

-Research & educational capacity: enhances or promote societal understanding of adaptation & the actions that can be taken - June of 2002 ptbo experienced a 1 in 100 year event storm requiring provincial disaster assistance.

- July of 2004 ptbo experienced a 1 in 290 year event storm for a second time costing over $100 million in direct damage. A state of emergency was declared to clean & restore major functions of the city.

- 2005 flood reduction master plan does not consider climate change Effects on Peterborough What can we do? -Cut emissions
-Work with nature
-Stop wetland drainage
-Restore our environment
-Renew agriculture
-Reduce threats
-Enhance resilience
-Engage people
-Share Knowledge Micheal Thrasher Natural Law - How we must learn about the environment around us

- We need to understand two things:
1) Ourselves
2) Our world

- "We are in a time of global warming, in our lifetime"
"The Earth goes through cycles such as the ice age, global warming is now!"

- Natural Law -> Change is. Model 3 Model 2 Model 1 Definitions Anthropogenic Climate- humans are the cause of Earth`s future climate/ atmoshperic state.

Forced fluctuations- Human caused

Unforced Fluctuations- Natural; what is done by the Earth processes
