NASA's current fleet of Earth-observing satellites. The following interactive presents selected highlights from the report: ![]() The 1.5-degree Celsius threshold represents the target goal established by the Paris Agreement, adopted by 195 nations in December 2015 to address the threat of climate change. The report examined the impacts of limiting the increase in global average temperature to well below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels, and projected the impacts Earth is expected to see at both 1.5 degrees and 2 degrees Celsius warming above those levels. The IPCC is the United Nations body tasked with assessing the science related to climate change. To assess the likely impacts of global warming on our planet at various temperature thresholds above pre-industrial levels (considered to be the time period between 18), the Intergovernmental Panel on Climate Change (IPCC) in October released a Special Report on Global Warming of 1.5 Degrees Celsius (2.7 Degrees Fahrenheit). While the plight of sea turtles is illustrative, it’s a fact that all natural and human systems are sensitive to climate warming in varying degrees. At sand temperatures of 31.1 degrees Celsius (88 degrees Fahrenheit), only female green sea turtles hatch, while at 27.8 degrees Celsius (82 degrees Fahrenheit) and below, only males hatch. Since the temperature of the beach sand that female sea turtles nest in influences the gender of their offspring during incubation, our warming climate may be driving sea turtles into extinction by creating a shortage of males, according to several studies. ![]() Earth’s warming climate is exposing sea turtles to greater threats that may threaten their survival. ![]()
