Climate Science Conversations by Alan Emery

The subject of climate science has essentially three discussions going on at the same time, all of which feed into the decision-making processes that will ultimately determine the use of climate science as it is applied (or not applied) to controlling global warming. Because these discussions often reach just about anyone who is the least bit connected to the communication systems of the world, it is important to understand how each operates and how they can and will determine the decisions of politicians, industry leaders, and even how the decisions will enable or disable climate research.

OPINION: Nuclear Reactors

OPINION: Nuclear Reactors

Small modular reactors are great, in their place. They are great for powering submarines and surface warships. They could be great for powering the world’s merchant marine — and that nuclear-powered fleet could remove a lot of CO2 in two ways — first by replacing the old smokers, and second, by extracting dissolved CO2 from their condenser cooling water — or even by making synthetic petroleum.

Dust in the air

The animations represent aerosol optical thickness from a portion of GEOS-5 simulation from September 2006 to April 2007. Major tropospheric aerosol types are emitted into the atmosphere and transported by winds, turbulence, and deep convection across the globe. Dust is represented with orange to red colors, sea salt with blue, organic and black carbon with green to yellow to white, and sulfates with ash brown to white. The yellow and red dots on the land surface indicate the locations of wildfires and human-initiated burning that have been detected by the MODIS instrument aboard the NASA Terra and Aqua satellites

Measuring the greenhouse gas effect of CO2

Measuring the greenhouse gas effect of CO2

The greenhouse gas effect can be complicated to understand. It is important because it is the mechanism that causes global warming. By adding excess CO2 from fossil fuels, poor forestry practices, poor agricultural practices, and using carbon-intensive industrial processes, we enable the greenhouse gas effect to increase our planet’s average temperature. Too much of this is going to be a very bad idea, so understanding what is happening is smart. Here are some details with a “sort of” simple explanation to start with.
