Dr. Shaina Sadai Talks About COP27, Climate Justice, Sea Level Rise, and Corporate Accountability

Union of Concerned Scientists

An expert on sea level dynamics and climate justice within the UN negotiations, Dr. Sadai is working to ensure that her scientific studies get in the hands of decisionmakers who are shaping our world today. SS: My climate change research journey began in 2015 when I started my Ph.D. at UMass Amherst.

The Fossil Fuel Industry Continues Producing Heat-Trapping Emissions that Drive Climate Change

Union of Concerned Scientists

My fellowship is based on using data that trace heat-trapping emissions to major fossil fuel producers in order to understand how they have affected the climate, particularly global sea levels, and to aid efforts to hold these producers accountable. I’ve marked these important years with dotted lines in Figure 2.

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.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.

The water south of Greenland has been cooling, so what causes that?

Real Climate

Finally, some have suggested that the cold blob south of Greenland has been caused by increased heat loss to the atmosphere.

Why is future sea level rise still so uncertain?

Real Climate

Three new papers in the last couple of weeks have each made separate claims about whether sea level rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty.

Mangrove restoration scales up in Indonesia

A Greener Life

As the risks of sea-level rise, stronger tropical storms and seawater intrusion grow due to climate change , Indonesia is ramping up efforts to protect mangrove ecosystems across the archipelago as part of both its COVID-19 recovery efforts and climate change commitments.
