How Hot Will It Get

The Nature Climate Change in a new study  is gaining widespread attention, and other scientists are agreeing with its conclusions. As Inside Climate News says in its report on the research:

By the time children born today are in their 80s, New York will have 50 days per year with temperatures and humidity exceeding the threshold beyond which people have previously died due to hyperthermia, if no steps are taken to curb greenhouse gas emissions. Sydney would face 20 deadly heat days a year by 2100, and Los Angeles would face 30 under a "business as usual" scenario. The study notes that the consequences of exposure to deadly climatic conditions will be aggravated by an aging population, since elderly people are more vulnerable to heat mortality, and by increasing urbanization, because of the heat-trapping effect of asphalt surfaces, building materials, and reduced vegetation.

For Orlando and Houston, deadly heat would last the entire summer by 2100 without steps to reduce greenhouse gas emissions, the study projects. Indeed, even though the degree of future warming is projected to be greater in temperate zones and at the poles, the greatest risk to people from deadly heat events will be at zones closer to the equator, because of the additional impact of humidity. …

The study bolsters previous research projecting increasing risk to humanity due to heat waves because of climate change.
