Earth Hour 2018 – The World Goes Dark

Once again, the earth has gone dark.  Every year since 2007, thousands of public buildings and landmarks around the globe are switched off  for an hour to raise awareness for climate change. Earth Hour 2018 started in Samoa and spread to all continents.

Numerous sites, including Sydney’s Opera House, the Paris Eiffel Tower and Brandenburg Gate in Germany, went dark at exactly 8.30 pm local time. In addition, millions of private citizens joined in the event and turned off lights in their homes. 187 countries took part in this years Earth Hour , organised by the WWF.

In the past the Earth Hour movement has achieved breakthroughs in  many environmental fields. In 2014 Ecuador’s government banned the use of plastic bags on the Galapagos island. Solar-powered lights were  installed in remote villages in India and 17 million trees were planted in Kazakhstan.

According to the WWF, Earth Hour 2018 will concentrate on the preservation of forests and oceans, as well as wildlife protection. The organisation says that it hopes to raise awareness of global warming especially in the USA, where President Trump has vowed to pull out of the Paris Climate Agreement.

German Cities Plan To Start Free Public Transport

German cities are planning to start free public transport services. The German government has suggested this action after the country, together with 7 other EU member states, have not met EU air quality standards. Pollution, especially in large cities, has become a major problem.

Free public transport will be introduced in five cities including Bonn, Essen and Mannheim by the end of the year.

Some major cities have already experimented with free transport services.  In Estonia’s capital Tallinn, residents have been able to use buses, trams and trains in the city for free since 2013. Paris and Seattle have tried offering free public transport, but only for a short time.

Germany’s decision to provide free public transport could prove to be expensive for its taxpayers. Many transport services get up to half of their money through ticket sales. Thus, the federal government would have to subsidize free transport in cities heavily. Experts claim that it may cost up to 12 billion euros in extra money to run the system for free.

Critics of the proposal say such a measure could put too much burden on public transport systems in large cities. Berlin, Hamburg and Munich already have major problems during rush hours and experts state that inviting more people to use public transport would overload existing systems. As a result, even more money would be needed to expand the country’s public transport services.

In addition to making cities as car-free as possible, car-sharing schemes, low emission zones and incentives for buying electric cars are also measures that are being considered.

NASA Software Shows How Sea Level Rises Affect Cities

NASA scientists have created a new software program that can show how cities in coastal regions are endangered by flooding and sea level rise caused by global warming. The simulation shows how 300 coastal cities will be affected in the next century.

The software was developed by  NASA’s Jet Propulsion Laboratory. It calculates which ice sheets and glaciers are melting and how the additional water influences coastal regions. It takes into consideration the rotation of the Earth as well as the influence of gravity. The results are surprising. Sea levels will actually decrease around cities closer to ice masses, while the biggest rises will occur through ice caps that are farther away.

New York, for example,  will be most affected by melting ice caps in northeastern  Greenland. Sydney, on the other hand,  will actually be influenced by parts of Antarctica that are far away from Australia’s city.

The software aims at helping city planners prepare for sea level changes within the next few decades and how to keep ocean water out.

A climate report published this week shows that, since 1900, global sea levels have risen by about 20 cm, with half of the rise occurring in the last 25 years. Projections show that by 2100 ocean levels will rise by an average of 1 metre, however, the rise will not affect all coastal areas in the same way.

Smog Returns to Delhi

Deadly smog has returned to Delhi. Air pollution reached several times the level suggested by the World Health Organisation. People were told to stay indoors and not walk on the streets of the world’s most polluted city. Doctors declared a state of emergency and some schools in the city stayed closed.

Smog in northern India is a big problem, especially during the winter months. From November to March cold temperatures force pollutants and dirt particles closer to the ground, mixing with the foggy air. Low wind speeds and dust from construction sites have also contributed to high pollution levels in the area.

Environmentalists say that factories and traffic are the biggest causes of smog. In addition, farmers in northern India burn the leftovers of crops after harvest and therefore produce more smoke.

Critics say that Indian government is not doing enough to protect India’s second-largest city. New measures took effect last October. Traffic became more regulated and several power plants were shut down. Authorities also want to restrict the personal use of cars to every second day, a measure that already worked in the past.

Last November Delhi was hit by the highest air pollution levels in 20 years, forcing over a million children to stay at home. Researchers claim that 2.5 million Indians die of pollution every year.
