The temporary closure applies mainly to recreational travel across the border. It follows the agreement between the U.S. and Canada to close the northern border to non-essential travel, which was announced Wednesday. The restrictions will be reviewed after 30 days, Secretary of State Mike Pompeo said. 302

The weekday pickup service -- which begins Tuesday -- will restore access to 2.9 million physical materials in the library's collection for the first time since branches were closed in mid-March due to the COVID-19 pandemic. 224

The Washington Post alleged Thursday that Moore initiated a sexual encounter with a 14-year-old girl when he was 32. Three other women also told The Post that Moore pursued them when they were between the ages of 16 and 18 and he was in his early 30s. 251

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
