Researchers anticipate harmful nitrogen outputs to increase as a result of precipitation changes.
For the third day in a row, Phoenix has broken a daily high temperature record.
The devastating storm once known as Hurricane Harvey, already the biggest rainstorm in the history of the continental United States, delivered another punishing wave of rain Wednesday to Texas and Louisiana.
Officials press forward with emergency plan following string of collapses at Del Mar bluffs.
The storm dropped more than a foot of snow overnight in some places, making for a messy Thursday morning commute. And the nor’easter isn’t gone yet.
From Massachusetts to Virginia, the East Coast was pounded by a storm that threatened to break records. Nearly two million people lost power.
The wind known as the Diablo is picking up again, the air is dry, there is no rain in sight and the killer wildfires that have scorched the wine country of Northern California remain almost completely uncontained. Officials warned Wednesday that some of the big fires could merge. Amid these grim bulletins, the huge utility company PG&E acknowledged that the extreme winds late Sunday and early Monday had knocked trees into power lines in conditions conducive to wildfires.
The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations, we project that extremes of wet-bulb temperature in South Asia are likely to approach and, in a few locations, exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.
