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

Union of Concerned Scientists

Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. But what exactly would cause the AMOC to collapse?

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

Union of Concerned Scientists

The IPCC compiles scientific insights on climate change, informing policymakers and the public about risks and possible actions. In essence, combined with climate models, they provide a way to envision the consequences of different actions or inactions. What Are Future Climate Scenarios?

Attribution Science and EPA’s Reconsideration of the GHG Endangerment Finding

Law Columbia

With each successive rulemaking, EPA acknowledged that the evidence of endangerment had grown stronger over time due to the increasing severity of climate change, new observational evidence of climate impacts, and advances in scientific understanding of how climate change affects public health and welfare.

AR6 of the best

Real Climate

Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climate change was scant. Figure SPM 8.

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. Our job is to be thorough and verify questionable results.

Wildfire Threat to Texas Nuclear Weapons Facility Highlights Intersecting Risks

Union of Concerned Scientists

What role is climate change playing? As climate change increases the frequency or intensity of extreme events such as wildfires, heat waves, and heavy downpours, there is an increase in the potential for different types of risks to coincide or for a climate-related event to trigger a cascade of non-climatic consequences.

Climate adaptation should be based on robust regional climate information

Real Climate

Chris Lennard from the University of Cape Town takes us through different aspects of climate change adaptation. The good news is that there are some initiatives on climate change adaptation which involve climate scientists such as the Infrastructure and Climate Network ( ICNet Global ).
