Global Warming The Earth's climate has changed many times in the past. Subtropical forests have spread from the south into more temperate (or milder, cooler.

The Truth about Global Warming As seen through the eyes of a physicist Dr. Suzanne Willis, Ph.D Northern Illinois University June 29,2011.

MITIGATING CLIMATE CHANGE. WHAT WE KNOW The level of greenhouse gases in the atmosphere have increased, causing the Earth’s temperature to rise. One greenhouse.

Greenhouse Effect How we stay warm. The Sun’s energy reaches Earth through Radiation (heat traveling through Space)

Greenhouse Effect: The heating of the surface of the earth due to the presence of an atmosphere containing gases that absorb and emit infrared radiation.

Global Warming Rachelle Gawlista

 The main cause of climate change is the greenhouse effect.  This is the warming of the surface or lower atmosphere of a planet.  This is caused.

Climate Climate = characteristic weather of a region. Ex. 100 year pattern. Major Elements: Temperature Precipitation (Moisture)

Global Warming.

Heating of the Atmosphere

Objectives Review Vocabulary Explain the greenhouse effect.

The Greenhouse Effect A large majority of the insolation that is radiated back into the atmosphere gets absorbed by greenhouse gases. A large majority.

Atmospheric Heating Radiation Conduction Convection.

Climate Change Overview: Key Concepts. Climate vs. Weather What is weather? – Conditions of the atmosphere over a short period of time (e.g. day- to-day).

The Greenhouse Effect on Climate Change.  1. The sun’s rays warm up the land and the water.  2. Infrared rays bounce back to space.  3. Some are trapped.

Ch16: Global Warming-part 1 What is it? What causes it? Focus on Carbon Dioxide.

Climate Change -a change in a region’s climate. -Anthropogenic climate change – a change in a region’s climate that is primarily caused by human activity.

Warmup What are three natural ways in which climate changes? What timescale do these processes generally occur?

Starter Which is an effect of lower levels of solar radiation striking Earth? increased incidences of skin cancer decreased rates of photosynthesis increased.

Global Warming Causes “Greenhouse gases” collect in the atmosphere & trap infrared radiation (heat) in the Earth’s atmosphere The #1 Greenhouse Gas = Carbon.

Aim: How do increased carbon dioxide concentrations on our planet affect life?

Cloud formation and Atmospheric CO2. Cloud Formation There are a few ways clouds form 1.Rising Hot Air 2.Warm air over a cold body of water 3.On Mountainsides.

The Greenhouse Effect The sun emits solar radiation which the Earth absorbs (UV rays). The Earth emits its own energy (heat waves called infrared rays)
