Discussion of Carbon Dioxide (CO2) emissions often occur at the national level. Nations promise to lower emissions and scientists look for alternative energy sources. But new software is providing data for this emission reduction discussion at a local level. The software allows people to have a view into their carbon emissions on the level of a city, neighborhood, block and even household. Listen to learn how scientists and local officials are working together to track and understand emissions at the local level.

A United Nations report in 2014 shows that human activities are changing the planet. The scientists are more confident in their conclusions that humans are causing global warming. There are rising sea levels, higher temperatures and impacts on wildlife. This conversation with a public radio reporter looks at the long term trend in global temperatures and what humans can do to reverse the trend.

Scientists say it’s nearly certain that human activity and fossil fuels are warming the planet. The mainstream discussion focuses on alternative energy and reducing fossil fuel emissions. But the field of geoengineering is looking for more large scale and proactive things we can do to offset warming. Some see this as an exciting way to help the planet, others as a threat. Listen to learn about the strategies geoengineers are exploring to prevent further global warming.
