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. What are climate scientists demanding?

Climate models and climate impact studies use emission scenariosestimates of potential future changes in heat-trapping emissionsto help us see how choices made about emissions today can shape tomorrows climate. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. 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!) Figure SPM 8.

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.

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 ). Such professional debates should include climate scientists, the adaptation community, and prac titioners.

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. The danger is that the Antarctic sea ice is starting to behave like the Arctic, with sustained loss of ocean cover and consequent absorption of solar radiation.

Climate scientists at the Union of Concerned Scientists (UCS) have dubbed the six-month stretch from May through October the “ Danger Season.” Not only has much of what climate scientists have been warning about come to pass, many of the extreme weather events the planet is now experiencing are worse than they expected. “To
