Animated map of what Earth would look like if all the ice melted. We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. This would dramatically reshape the continents and drown many of the world's major cities. Produced by Alex Kuzoian
Lumpectomy (sometimes known as a tylectomy) is a surgical removal of a discrete portion or lump of breast, usually in the treatment of malignant tumor or breast cancer.
A colon resection (also known as a colectomy) is an inpatient procedure in which the cancerous portion of the colon is removed. To ensure all of the cancerous tissue is removed, a small portion of healthy colon tissue adjacent to the cancerous tissue may also be removed. On average, one-fourth to one-third of the colon may be removed during a colectomy. The remaining portions of the colon are then connected.
