Presentation transcript:

What Is Global Warming? Learning Objectives 1. Summarise the causes and effects of Global Warming 2. Identify and Describe perspectives on Global Warming 3. Communicate your ideas

What do I know? Causes ------------------------ Effects Perspectives What do I want to know? ----------------------------- In groups discuss and write your ideas

Glossary – please start a glossary with these words * Climate * Climate Change * Global warming * Global Average Temperature * Atmosphere * Greenhouse effect * CO2 * Methane * Deforestation * Desertification

Greenhouse effect- the warming of the surface by back radiation from the atmosphere Without the greenhouse effect the world would be frozen!

Temperature Change Temperature change is part of a natural process The world is coming out of an ice age or colder period The problem is that the warming is happening very quickly Describe and explain what this graph shows

An explanation of the causes of rapid recent temperature changes include Make your own copy of this diagram

This graph shows the increase in world temperature in the last 100 years Describe and explain what this graph shows What are some of the possible reasons for this?

Man made Greenhouse gases Make your own copy of this diagram

The possible effects of global warming

Describe what this map shows. Explain why some places are affected more than others Is this fair?

Viewpoints held about global warming by List groups who would oppose the idea of global warming and support it

Use the nisktobegp.weebly.com website to help you identify groups who agree or disagree with global warming ideas For 97% of scientists ------------------------------------------------------------ -------------------- Against Conservative groups -------------------- Global Warming Groups WHY? For each group come up with possible reasons for their perspectives
