An enhanced greenhouse effect from CO2 has been confirmed by multiple lines of empirical evidence.
Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials Teaching Tips Teaching Tips This short video should be used to clarify the role of carbon dioxide in absorbing infrared energy re-radiated from Earth's surface.
It will enhance student understanding of the greenhouse effect.
The teacher will need to prepare to lead discussion following the video, using the essay and links provided. About the Science Video includes a simple and effective demonstration of how carbon dioxide absorbs infrared radiation -- an idea often presented poorly in the usual discussions of the greenhouse gas effect.
Passed initial science review - expert science review pending. About the Pedagogy This resource includes a background essay, simple discussion questions, and links to national and state standards.
The background essay discusses the sources and sinks of carbon dioxide and the idea that some of the carbon dioxide emitted by human activities is unaccounted for. Technical Details The online version of the video is not of sufficient resolution for projection.
The downloadable version will work better.The Port of Rotterdam Authority is committed to combating climate change and wants to play a leading role in the global energy transition.
The reduction of CO2 emissions and efficient use of raw and residual materials are important tasks for the Port Authority.
For each greenhouse gas, a Global Warming Potential (GWP) has been calculated to reflect how long it remains in the atmosphere, on average, and how strongly it absorbs energy. Gases with a higher GWP absorb more energy, per pound, than gases with a lower GWP, and thus contribute more to warming Earth.
Carbon dioxide (CO2), more than any other climate driver, has contributed the most to climate change between and Radiative forcing units are expressed as the power (watts) per square meter surface area of Earth. Carbon dioxide can also be absorbed by the oceans. But as more CO2 is pumped out, more is accumulating in the atmosphere than the plants and oceans can take back. Global warming is caused by the emission of greenhouse gases. 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx). Carbon dioxide emissions therefore are the most important cause of global warming.

Hence, the climate history of the past half-million years provides absolutely no evidence to suggest that the ongoing rise in the air's CO2 concentration will lead to significant global warming.
Strong negative climatic feedbacks prohibit catastrophic warming.
Strong . Proponents of the notion that increases in the air's CO2 content lead to global warming point to the past century's weak correlation between atmospheric CO2 concentration and global air temperature as proof of their contention. These include the FAO’s Global Forest Resources Assessment, the Center for Global Development’s FORMA project, and three datasets on deforestation in the Amazon, which is the planet’s largest area of tropical forest.
