Global Warming

Morocco’s irrigation revolution against global warming

In 1980, 2,500 m3 of drinking water was available per person per year in Morocco. Today, as a result of global warming, water scarcity has brought the level down to 500 m3 per person. According to NASA, the global average temperature has increased by 1.1°C over the last century, which is causing more droughts.

In response, the agricultural irrigation sector in Morocco has boomed. The government aims to convert 550,000 hectares of agricultural land to drip-irrigation technology within 10 years.

Thousands march peacefully in Brussels against global warming

Tens of thousands of people marched peacefully on Sunday in Brussels urging governments to respect commitments on countering climate change as a United Nations conference on keeping global warming in check opened in Poland.

Belgian police said some 65,000 people participated in Sunday’s “Claim The Climate” demonstration, many of them on their bikes.

Global warming increases frost damage on trees in Central Europe

Global warming increases frost damage on trees in large areas of Central Europe, according to a new Finnish-Chinese study by researchers from the University of Eastern Finland, the Chinese Academy of Science and Zhejiang A&F University.

Late frost damages are economically important in agriculture and forestry. In certain years, they are known to have caused losses amounting to up to hundreds of millions of euros.

Climate change and increasing temperatures will diminish the occurrence and severity of spring frost events, which should reduce frost damages.

“However, global warming also has another, negative consequence: plants flower and leaf out earlier than they used to. As a result, the incidence of frost damages will increase,” says Professor Frank Berninger from the University of Eastern Finland.

“Our research suggests that as a result, trees will suffer increasing frost damages in many places in Central Europe.”

Space Events

Asteroid Probe

The National Aeronautics and Space Administration’s (Nasa’s) deep-space explorer Osiris-Rex flew on Monday to within 19km of its destination, a skyscraper-sized asteroid believed to hold organic compounds fundamental to life as well as the potential to collide with Earth in about 150 years.

Bennu, a rocky mass roughly a half a kilometre wide and shaped like a giant acorn, orbits the sun at roughly the same distance as Earth and is thought to be rich in carbon-based organic molecules dating back to the earliest days of the solar system. Water, another vital component to the evolution of life, may also be trapped in the asteroid’s minerals.

Scientists believe that asteroids and comets crashing into early Earth delivered organic compounds and water that seeded the planet for life, and atomic-level analysis of samples from Bennu could help prove that theory.

Scientists estimate there is a one-in-2,700 chance of the asteroid slamming catastrophically into Earth 166 years from now. That probability ranks Bennu number two on Nasa’s catalog of 72 near-Earth objects potentially capable of hitting the planet.

Disease

Hepatitis E – Central African Republic

In a follow-up on the hepatitis E outbreak in Bocaranga-Koui Health District, Central African Republic, since late October, 67 new cases of acute jaundice syndrome were reported, of which 51 were confirmed with hepatitis E virus infection. As of 23 November 2018, a total of 119 cases of acute jaundice syndrome were recorded, including two deaths.
