  • “The most up-to-date and comprehensive long-term analysis” of southwestern North America shows that a megadrought is happening in the region.
  • Data shows that there have been several other megadroughts in this area, which were caused by nature.
  • In this new situation, scientists say that human-origin climate temperature warming is making things worse than at least 3 previous recorded megadroughts.
  • The megadrought is in progress, natural water supplies in the region have “shrunk dramatically”.
  • However, there might be a wetter period for some time before the drought kicks back in, because natural variability plays a huge role in this process.
