Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase. Also, mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells.
If we continue to increase greenhouse emissions, more of it will build up in the atmosphere, meaning more of the Sun's infrared radiation will be trapped via the Greenhouse Effect. This will cause the planet to warm.
