How Do ‘Future Climate Scenarios’ Shape Climate Science and Inform Policy? 

Union of Concerned Scientists

Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100. Radiative forcing is the change in energy balance in the Earths atmosphere due to heat trapping emissions. These scenarios can also reveal how forests, oceans, and other natural systems might absorb or release carbon in the future.

New Satellite Will See Water’s Big Picture

Circle of Blue

Part of the Surface Water and Ocean Topography (SWOT) satellite’s science instrument payload sits in a clean room at NASA’s Jet Propulsion Laboratory during assembly. Instruments installed on the International Space Station are refining weather forecasts by measuring water vapor in the atmosphere and water held in clouds.

Delayed harm and the politics of climate change, reconsidered

Legal Planet

What are the political implications of the fact that climate change will continue after emissions cease, or even potentially grow worse? First, after carbon dioxide emissions cease, atmospheric carbon dioxide levels begin to decrease, as they are absorbed by natural processes and sinks in the oceans and on land. degrees Celsius.

Congress Needs to Carefully Chart NOAA’s Path Forward

Union of Concerned Scientists

In the US, when we check our local weather forecast, when our communities are recovering from an extreme weather event, or when our fisherfolk are at sea catching food, we are benefitting from the work of the National Oceanic and Atmospheric Administration (NOAA). NOAA has three main goals under its mission: “1.

Five Things to Know About Drought in the American West

Circle of Blue

A thirsty atmosphere evaporates or sublimates its share. With increasing temperatures, “we’re seeing places that do have drought, the intensification is more rapid,” says Roger Pulwarty, a senior scientist in the physical sciences laboratory at the National Oceanic and Atmospheric Administration. 4) Drought Is Political.

Whales and Lobstermen Have a Common Enemy

Union of Concerned Scientists

A simple statement that masks just how complicated the issues are: mixing politics, economics, livelihoods, fisheries and endangered species in the ocean body that is the Gulf of Maine. He was on to something And the lobsterman was correct: we can blame carbon emissions for ocean acidification and warming in the Gulf of Maine.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.
