Is global warming preventing an ice age?
Yes. Then No. Global warming is not going to lead to an even temperature rise around the globe in the way of the daily temperatures are going to be warmer. It means that there is more heat in the system on a global scale. Heat is the driving force of weather and local and micro climates. El Nino, when the Pacific warms up near the Americas results in wetter and sometimes cooler winters for the West coasts of the the Americas. There is more heat in the system (the eastern Pacific) resulting in a change in climate for the Americas. also Asia, Australia and even the Eastern coasts of Africa are dryer in those years. Where we may think that more heat results in hotter days, the end result is often cooler wetter days. Another thing being affected by more heat, thus more ice melt is the oceanic currents that move vast amounts of water from equator to po
