The basic physics of how global warming contributes to sea-level rise has long been understood, but new research gives us a clearer picture of what to expect. Prior to the 1990s, most sea-level rise was attributed to melting glaciers and the thermal expansion of warming ocean waters.
When people read about climate change and sea level rise in the average mass-market, general-interest publication, they nearly always see references to “average global sea level rise” – for instance, that the worldwide average sea level rise will be about three feet (or six feet) by the end of th
If anthropogenic greenhouse gas emissions are not drastically curtailed within the next two to three decades, sea-level rise will displace tens of millions of people worldwide – and potentially many more – in the latter decades of the current century and the early decades of the next.
Florida’s Miami-Dade County is extremely vulnerable to rising seas, and its options for adaptation are limited. One of the biggest challenges facing residents of the region is to overcome psychological barriers to climate action.
As the reality of a carbon-neutral market and future takes form, all available resources will need to be focused upon removing carbon dioxide from the atmosphere. In this regard, no alternative is more promising today than nature-based solutions.
In 1965, the US Atomic Energy Commission made a fateful decision to license nuclear power plants that, top safety experts believed, had containment structures that were inadequate to contain dangerous releases of radioactivity in the case of core-melting accidents.
