However, the effects of human-made climate change will be so long-lasting that they could prevent the next ice age from ever happening. "Such a transition to a glacial state in 10,000 years' time ...

Sea ice reduction happens when more sea ice melts during the summer compared to what freezes during the winter. Last year was Earth's warmest year on record. The Global Carbon Project found that ...
