Transcript of Climate Change

What is Climate Change? Climate Change is the climate of a place or region is changed if over an extended period(typically decades or longer), there is a statistically significant change in measurements of either the mean state or variability of the climate for that place or region. The rise in temperature on earth caused by gases in the atmosphere trapping energy/heat from the sun. Without the gases, the heat would go back into space and earth would be about 60 degrees Farenheit cooler. Impacts of Climate Change Warmer waters cause hurricanes which cause mass destruction and lots of money. Warm weather can cause insects who carry disease to migrate. Droughts Polar ice caps melt which cause: Sea levels rise
Freshwater/saltwater combine
Temperatures rise and animals are in danger Causes of Climate Change CO2 and other greenhouse gases
Land use changes (urban areas growing causing housing development
Solar variations
Continental drift
Earth's tilt (less tilt=cool summers, mild winters; more tilt=warm summers, cold winters
Humans increasing the greenhouse effect gases makes us contributers to global warming. What is the Greenhouse Effect? Water Vapor
Carbon Dioxide
Nitrous Oxide
Methane Greenhouse Gases Greenhouse Effect Evidence of Climate Change Increased levels of CO2
Increased ocean temperatures
Higher ocean acidity
Arctic sea ice melting
Drastic erosion of shorelines Humans are impacting climate change! Burning fossil fuels
Aerosols
Cement manufacturing
Land use
Deforestation Reducing Climate Change complete home energy audits
Plant a tree
Use less hot water
Use Compact Fluorescent bulbs
Reduce, Reuse, RECYCLE!!
Eat less meat
Buy organic produce
Compost your food Amazing Fact 1 tree will absorb approximately 1 ton of CO2 in it's life! More cool facts If everyone changed one incandescent bulb to one CFL bulb in their home, then it would eliminate 90 billion pounds of greenhouse gases. That is equivalent of taking 7.5 million cars off of the road! Created by: Morgan Hamersky
Mallory Lutz Climate Change Here's How: Evidence and How to Help Why do we care? shores are eroding because of rising sea level This means that coastlines with cities like New York, San Fransisco, and suburbs where many people live will be underwater. When the sea is closing in, everybody will flock to landlocked places like Kansas. Ozone is deteriorating With the ozone disappearing, there is nothing left to block harmful radiation from the sun. This radiation causes skin cancer, damage to crops, cataracts, and so on. Plus the earth will be heating up--fast. It may take 50 years to replenish the ozone. Animals are in danger Some animals, like the polar bear, are in danger of losing their habitats. Without anywhere to live, the animals face extinction.
