When El Nino is around, Hawaii and Australia tend to be quite dry, because it causes a change in the position of the high pressure in the Central Pacific. Conversely, it tends to bring wetter conditions in South America, especially in Peru, Bolivia, and Colombia. It causes changes in the currents, with the worst causing a reversal of the trade winds, so instead of going east to west like it normally does, it reverses and goes from west to east, and that pushes the warm water to South America. But Hawaii has lately been struggling to stay within normal rainfall over the last few years, even during the opposite phase, La Nina. It's not limited to Hawaii. Much of South America and parts of Europe are struggling to deal with that, the former of which is in their winter, but I read somewhere that parts of Chile, Argentina, Paraguay and Brazil are getting record high temperatures. Here in Florida, I read some of the ocean temperatures were in the upper 90s to near 100 in the Florida Keys. If a hurricane were to pass that area, it could rapidly intensify. In fact, while traditionally the hurricane season starts in June, lately it has been .starting earlier over the last 10 years. The last time a year did not have either an El Nino or a La Nina for at least part of the year was 2013 Yes, climate change is definitely happening, but the big question is, what is the world going to do about it? Obviously the answer would be to reduce dependence on oil, coal, and gas, but it's not that simple. Not every country has the infrastructure to build renewable sources or people that know how to do it, especially in places like Africa, Middle East, India, etc. So we probably will likely see this sort of thing happen more frequently. Another thing that likely will increase? Tropical diseases. With warmer temperatures, things that cause diseases (e.g. ticks, mosquitoes) will expand their range. I just don't see how we can reverse this because it takes anywhere between 300-1000 years for the atmosphere to remove the excess CO2. To put that into perspective, that would take the equivalent of between 1-4 orbits of Pluto (each taking 248 years) for it to decrease, and that's if we cut emission to zero suddenly. I think humanity is not prepared for what is about to happen.
