Summary:

- According to a new study, the next natural ice age would have begun in about 11,000 years if it weren't for human-caused climate change. However, the researchers say that climate change has likely pushed the next ice age back by at least 50,000 years.

- The study used computer models to simulate the Earth's climate over the next 100,000 years, taking into account factors like changes in the planet's orbit and tilt, as well as greenhouse gas emissions. The models showed that without human influence, the planet would naturally cool and enter a new ice age in about 11,000 years.

- However, the researchers found that the high levels of greenhouse gases humans have added to the atmosphere have disrupted this natural cycle, likely delaying the next ice age by at least 50,000 years. This highlights the significant impact that human-caused climate change is having on the planet's long-term climate patterns.
