His proposal for a global climate council — a smaller, more agile entity to lead negotiations and ensure that climate commitments are implemented — reflects mounting frustration with the slow pace of outcomes from the annual Conference of the Parties (COP).How to fight climate change…

Will computers ever match or surpass human-level intelligence — and, if so, how?

Foods containing gluten, a protein found in wheat, barley, and rye, are also considered a common culprit that worsens bloating, diarrhea, and abdominal pain.
