Hundreds of Philippine Schools Suspend Classes over Heat Danger

Hundreds of schools in the Philippines, including dozens in the capital Manila, suspended in-person classes on Tuesday due to dangerous levels of heat, education officials said.
The country's heat index measures what a temperature feels like, taking into account humidity.
The index was expected to reach the "danger" level of 42 degrees Celsius in Manila on Tuesday and 43C on Wednesday, with similar levels in a dozen other areas of the country, the state weather forecaster said.
The actual highest temperature forecast for the metropolis on Tuesday was 34C, reported AFP.
Primary and secondary schools in Quezon, the most populous part of the city, were ordered to shut while schools in other areas were given the option by local officials to shift to remote learning.
Some schools in Manila shortened class hours to avoid the hottest part of the day.
A heat index of 42-51C can cause heat cramps and heat exhaustion, with heat stroke "probable with continued exposure", the weather forecaster said in an advisory.
Heat cramps and heat exhaustion are also possible at 33-41C, according to the forecaster.
Local officials in several areas of the southern island of Mindanao also suspended in-person classes or shortened school hours over two weeks, regional education department spokeswoman Rea Halique told AFP.
The orders affected hundreds of schools in the provinces of Cotabato, South Cotabato and Sultan Kudarat, as well as the cities of Cotabato, General Santos and Koronadal, Halique said.
Cotabato city experienced the highest heat index in Mindanao, reaching 42C on Monday and Tuesday, the state forecaster reported.

African elephants are Earth's largest land animals, remarkable mammals that are very intelligent and highly social. They also are in peril. Fresh evidence of this comes in a study that documents alarming population declines at numerous sites across the continent over about a half century.

Researchers unveiled on Monday what they called the most comprehensive assessment of the status of the two African elephant species - the savanna elephant and forest elephant - using data on population surveys conducted at 475 sites in 37 countries from 1964 through 2016.

The savanna elephant populations fell by about 70% on average at the surveyed sites and the forest elephant populations dropped by about 90% on average at the surveyed sites, with poaching and habitat loss the main drivers. All told, there was a 77% population decrease on average at the various surveyed sites, spanning both species, Reuters reported.

Elephants vanished at some sites while their populations increased in other places thanks to conservation efforts.

"A lot of the lost populations won't come back, and many low-density populations face continued pressures. We likely will lose more populations going forward," said George Wittemyer, a Colorado State University professor of wildlife conservation and chair of the scientific board of the conservation group Save the Elephants, who helped lead the study published in the journal Proceedings of the National Academy of Sciences.

Poaching typically involves people killing elephants for their tusks, which are sold illegally on an international black market driven mostly by ivory demand in China and other parts of Asia. Agricultural expansion is the top factor in habitat loss.

The forest elephant population is estimated to be about a third that of savanna elephants. Poaching has affected forest elephants disproportionately and has ravaged populations of both species in northern and eastern Africa.

"We have lost a number of elephant populations across many countries, but the northern Sahel region of Africa - for example in Mali, Chad and Nigeria - has been particularly hard hit. High pressure and limited protection have culminated in populations being extirpated," Wittemyer said.

But in southern Africa, elephant populations rose at 42% of the surveyed sites.

"We have seen real success in a number of places across Africa, but particularly in southern Africa, with strong growth in populations in Botswana, Zimbabwe and Namibia. For populations showing positive trends, we have had active stewardship and management by the governments or outside groups that have taken on a management role," Wittemyer said.

The study did not track a continent-wide population tally because the various surveys employed different methodologies over different time frames to estimate local elephant population density, making a unified head count impossible. Instead, it assessed population trends at each of the surveyed sites.

A population estimate by conservationists conducted separately from this study put the two species combined at between 415,000 and 540,000 elephants as of 2016, the last year of the study period. It remains the most recent comprehensive continent-wide estimate.

"The loss of large mammals is a significant ecological issue for Africa and the planet," said conservation ecologist and study co-author Dave Balfour, a research associate in the Centre for African Conservation Ecology at Nelson Mandela University in South Africa.

The world's third extant elephant species, the slightly smaller Asian elephant, faces its own population crisis, with similar factors at play as in Africa.

Of African elephants, Wittemyer said, "While the trends are not good, it is important to recognize the successes we have had and continue to have. Learning how and where we can be successful in conserving elephants is as important as recognizing the severity of the decline they have experienced."

Wittemyer added of these elephants: "Not only one of the most sentient and intelligent species we share the planet with, but also an incredibly important part of ecosystems in Africa that structures the balance between forest and grasslands, serves as a critical disperser of seeds, and is a species on which a multitude of other species depend on for survival."
