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

Union of Concerned Scientists

If you live in a coastal zone and have looked at maps of future sea level rise or have read about how climate change could be slowed with policy changes to reduce emissions, youve likely seen these scenarios in action. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.

Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

For the United States, an AMOC collapse would lead to warmer ocean temperatures and greater sea-level rise along the East Coast, leading to devastating impacts on fisheries and ecosystems in the coastal Atlantic Ocean, as well as greater flood risk to coastal communities and infrastructure.

Sea level rise is a big deal Use, abuse and misuse of the CMIP6 ensemble The radiative forcing bar chart has gone full circle Droughts and floods are complicated Don’t mention the hiatus. Sea Level Rise: The previous IPCC reports, notably AR4 and AR5 (to a lesser extent) , have had a hard time dealing with SLR.

“Fighting for Inches” in the Southeast’s Struggle With Salt

Circle of Blue

Despite promising adaptation strategies, sea level rise is projected to drown tens of thousands of acres of farmland within the century. Atlantic sea levels are rising three to four times faster than the global ocean average. Crop damage radiates inward gradually from the edges of a field, where the salt hits first.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

While temperatures provide a measure of the Earth’s climate, it is even better to use the global sea level , which provides a far more reliable measure. The global sea level acts like the mercury in a thermometer because warmer water expands.

Analysis: How fast can we stop Earth from warming??

A Greener Life

Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room. The radiators are, in fact, cooling down, but their stored heat is still warming the air in the room.
