Climate Change: a Brief History
What is Climate Change?
The last 650,000 years- Seven cycles of glacial advance and retreat
Ice age ends 7,000 =Modern Climate Era and Human Civilization
Most caused by small variations in earth’s orbit
Current trend 95% because of human activity since mid 20th century and is proceeding at a rate that far exceeds any other decades previous
Countries Affected by Climate Change and How
Climate change affects us all
Modern Industrialization/Fossil Fuels
Depletion of the ozone layer
Summer sea ice in Arctic dwindles.
Glaciers shrinking worldwide/affects runoff and water resources which rise sea level
Warming and thawing in the high elevations is causing permafrost to degrade.
Many species shifted their geographic ranges, activities, and migration patterns.
The oceans are acidifying by absorbing C02 from humans causing coral reefs to die.
The effects of Climate Change on the world population as a whole
Global problems are everyone’s problems
Act now! Our time is running out!
climate change is already having substantial impacts on the entire world
Climate Change Impacts Around the World
Brief History of Energy Sources
Nonrenewable energy sources
Renewable energy sources
First was Sun then fire and wind
Before 1850 Wood was main source
Natural Gas early as 500 BC by Chinese
1816 Natural Gas
1945 to present- nuclear, solar, water and wind
Countries Affected by Energy Sources and How
Positive effects of countries using Renewable Sources
Iceland, Sweden, Costa Rica, Nicaragua
The effects of Energy Sources on the world population as a whole
Brief History of Lack of Educational Opportunities
Marginalization and poverty
Financial deficit of developing countries
Inequality between girls and boys
Countries Affected by Lack of Educational Opportunities and How
more than 72 million around the world remain unschooled.
Central and Eastern Asia, as well as the Pacific
The effects of Lack of Educational Opportunities on the world population as a whole
The world is becoming smaller
What affects one country affects us all
Education is the key to growth and assistance
Brief History of Inappropriate Uses of Technology
History of technology
From stones fire and knives
To supercomputers, Cell phones, and Artificial Intelligence
Where there is man there is good and bad
Countries Affected by Inappropriate Uses of Technology and How
Developing and Poor Countries
Developed and Rich Countries
No one is safe
Nuclear Power= World Power
The highest technology is one step ahead
The effects of Inappropriate Uses of Technology on the world population as a whole
Poor vs rich Countries
Level of importance based by Countries
