Atlantic Meridional Overturning Current helps regulate global temperatures; ice melt from ice sheets and decreases in salinity could create problems over course of decades, not centuries
A tipping point occurs when a temperature crosses a no-return threshold. Think of leaning back in a chair further and further. With better climate data, improved resolution of climate systems, and more accurate climate models, we know we have moved into the danger zone
The world is just about as ill-prepared for the next climate disaster as the doomed steamship. Even serious planning will fail if we limit ourselves to standard command-and-control disaster protocols.
Providing Ukraine with our military aid/technology also improves our own security. It allows the U.S. to restock what we send from our armories with new, often with more advanced, replacements. Have Republicans forgotten this?
