Pressure mounts on aviation industry over climate change

Under pressure from frequent flyers alarmed over climate change, the airline industry says it is "hellbent" on reducing emissions—but the technology needed to drastically reduce its carbon footprint is still out of reach.

Here comes the sun

It's no surprise Western Australia has a lot of sunshine. But what are we doing with it?

Emissions rose an 'unsustainable' 2% in 2018: study

Global carbon emissions grew by 2.0 percent last year, the highest rate since 2010-2011, a closely-watched review by energy giant BP said Tuesday, calling the trend "unsustainable".

Coal-hungry S.Africa introduces carbon tax

South African President Cyril Ramaphosa has signed into law a carbon tax to cut emissions in the continent's worst polluter, the treasury said Monday, drawing cautious praise from environmentalists.

One change can make diet more planet friendly

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".
