German climate plan brings sharp air travel tax hike

Chancellor Angela Merkel's cabinet will sign off draft laws on new green taxes and subsidies this week, including much harsher charges on short-haul flights, German government sources said Tuesday.

New material captures carbon dioxide

A new material that can selectively capture carbon dioxide (CO2) molecules and efficiently convert them into useful organic materials has been developed by researchers at Kyoto University, along with colleagues at the University ...

How to make carbon pricing palatable to air travellers

Travellers are willing to pay a little more for flights if they know the extra money will be used to address carbon emissions, a new study from the UBC Sauder School of Business has found.

Study: Carbon emissions soar as tourism reaches new heights

A researcher at The University of Texas at San Antonio (UTSA) is examining how the flight routes people take to get to tourist destinations impact the amount of pollution in the air in a newly published study he coauthored ...

Greenhouse gas

Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In our solar system, the atmospheres of Venus, Mars and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33°C (59°F) colder than at present.

Human activities since the start of the industrial era around 1750 have increased the levels of greenhouse gases in the atmosphere. The 2007 assessment report compiled by the IPCC observed that "changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system", and concluded that "increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century".
