The report is mandated by law and produced by scientists from 13 federal agencies. Many experts consider it one of the most comprehensive reports on climate science, and some worried the administration would suppress or dismiss it. 241

The school needs .5 million in pledges before they can begin recruiting students this year for the 2020 school year. So far, the school is million short of its goal.For more information on the upcoming Cristo Rey school in San Diego, including how to donate, visit www.cristoreysandiego.org. 296

The school district has also proposed tearing down the building where the shooting happened, Parkland Mayor Christine Hunschofsky said. 135

The quake left the busiest city in Mexico in chaos. Windows buckled and shattered, falling several stories to the ground while thousands of people streamed into the streets running away from buildings and potential gas leaks. 225

The projections are based on research showing that humans cannot survive beyond a certain threshold of temperature and humidity.That threshold was determined by a measurement called the wet-bulb temperature (WBT), which is gauged by wrapping wet cloth around the bulb (or sensor) of a thermometer, so that evaporation of the water can cool the bulb.In a wet-bulb temperature of 35 degrees Celsius, a healthy person may not be able to survive outdoors for more than six hours, research has shown.The MIT study shows that the risk of deadly heat waves is significantly increased because of intensive irrigation in this relatively dry but highly fertile region.The new research found that unless greenhouse emissions are cut the deadly wet-bulb threshold temperature of 35 degrees Celsius will be reached several times in the north plain region between 2070 and 2100.Increased vulnerability to heat arises because the irrigation exposes more water to evaporation, leading to higher humidity in the air than would otherwise be present and exacerbating the physiological stresses of the temperature, according to the report's authors."Irrigation exacerbates the impact of climate change," Eltahir said. There has been a substantial increase in extreme heat waves in the region already in the last 50 years, he added.The report states that under the business-as-usual scenario of greenhouse gas emissions, the plain "is likely to experience deadly heatwaves...exceeding the threshold defining what Chinese farmers may tolerate, while working outdoors without air conditioning."It concludes the conditions "may necessitate simultaneous development of effective public health adaptation measures to avoid the deadly impacts of future heatwaves." 1737
