The Colossus Storms were a series of hurricanes and mega-tsunamis that devastated the Earth starting in the late 2030s and throughout the 2040s and 2050s. The Colossus Storms are considered a primary catalyst for the ensuing global events of the following decades.

The Colossus Storms began with the rapid melting of the polar ice caps. The rise of global sea levels contributed to slowing down the flow of oceanic currents. This process created "hot spots" throughout the planet where temperatures were raised to near-unbearable highs. This dramatic change in global weather patterns was drastic enough to create a new breed of superstorms that were previously unthinkable. The first of these came in the year 2038: a storm named Hurricane Yara. This superstorm super-storm saw sustained wind speeds of almost 380 kilometres-per-hour and deemed the first ever Category Six hurricane. The primary target of Yara was the Florida Keys and the area became irreversibly flooded with the death toll somewhere in the hundreds of thousands and the number of displace peoples in the millions. Just one month after Hurricane Yara, Typhoon Tamaraw posted sustained wind speeds of 395 kilometres-per-hour. Primarily targeting Manilla, it caused more deaths and more destruction than any storm in human history.

This was followed by Typhoon Kulap. This would be the first storm to break through the 400 kilometre-per-hour barrier, easily making it the largest storm in human history. It hit Kolkata and Pondicherry, two cities almost two-thousand kilometers apart, at the same time. This pattern continued. Hurricane Samuel struck and completely submerged New Orleans and South Texas. Hurricane Alita, made landfall in Charleston and caused floods as far as Denver.

The Global Mind Project had predicted such storms would occur, but the project was still considered as fantasy by many global powers and repeated warnings were ignored. By the time they started to hit prediction was essentially useless anyway as none of the infrastructure was in place. Eventually Container Walls, superstructure dams designed to hold back millions of tons of water, were built to mitigate the damage of future storms.

The Colossus Storms irreversibly changed the course of the planet. After the first series of storms, more than 100 different world cities were basically uninhabitable due to flooding and other environmental problems. The storms, and other compounding factors of global warming, led to global food insecurity that affected over one-billion people. Entire regions disappearing off the world map led to hundreds-of-millions more migrating to new nations. These stressors led to a series of wars that reframed the landscape of several nations and the geopolitical balance of the world. The most prominent was the Second American Civil War, which completely reframed the entire power structure of world superpowers.

The Colossus Storms were a major catalyst for climate action. After the storms, even the staunchest climate change deniers changed their opinions. Almost every nation contributed to the Global Mind Project creating the first truly meaningful global climate change initiative. As almost every country made the switch to green energy and worked on technology to reverse some of the effects of global warning, the environment stabilized. Massive storms still occur in on a regular basis, but by 2084 storms the level of the Colossus Storms have ceased.
