After hitting 100 degrees Wednesday, Portland’s light-rail trains are operating at slower speeds amid concern that the heat will cause tracks to expand and risk a derailment. In exchange for the slow service, inspectors are not checking riders for tickets.

In 2015, South Asia experienced a deadly heat wave that killed roughly 3,500 people in Pakistan and India in a matter of months. New research suggests the region could face much worse by the end of the century.

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.

To varying degrees, nearly the entire state was warmer than normal this July, according to a weather expert.

Australia has had its warmest July on record, the Bureau of Meteorology (BOM) has said. A BOM report released today shows the country's average July temperature was at its highest in more than 100 years of weather recording.

By the end of the century, the global temperature is likely to rise more than 2 degrees Celsius, or 3.6 degrees Fahrenheit.

In July 2017 extremely high temperatures were recorded all over Cyprus. Specifically, the mean provisional daily maximum temperatures of Athalassa, Prodromos, Pafos Airport, Larnaka Airport and Paralimni are a record of high temperatures of July and rank July 2017 as the hottest for at least the last 30 years.

Researchers anticipate harmful nitrogen outputs to increase as a result of precipitation changes.

AUSTRALIA has just endured its second driest June in more than a century as the country’s virtually rainless winter continues.

Weather patterns have changed so much in the past several years.

FAIRBANKS - A windstorm knocked out power to thousands of people from North Pole to Nenana on Sunday, according to the Golden Valley Electric Association.

There is a warning from Island Health about a poisonous mushroom known as the "Death Cap", which has been spotted in residential areas near Victoria.

Hot, dry weather over the northern Interior is keeping wildfire season alive longer than normal.

We are losing coastline due to erosion and this is a sad sight to witness.

Weatherwatch A recent heatwave in Siberia’s frozen wastes has resulted in outbreaks of deadly anthrax and a series of violent explosions

In some recent years, GHG emissions from BC wildfires have been more than from all other sectors put together

The potentially fatal death cap mushrooms that killed a three-year-old boy last year are popping up early in Uplands. The mushroom, known by the scientific name Amanita phalloides, was discovered.

A mycologist said the Amanita phalloides has sprouted up in Victoria again.

France has launched a special smartphone application to track a rocketing plague of ticks, which cause over 30,000 cases of Lyme disease par year and pose a threat to thousands of British holidaymakers who take to the French countryside in summer.

Island Health confirms the fungus, known scientifically as Amanita phalloides, has already flowered in Uplands this July.
