7 trends in the world environment in 2015

El Nino, ocean acidification or water shortages are three of the most significant problems that could affect Earth this year.

El Nino phenomenon.The National Oceanic and Atmospheric Administration (NOAA) said that El Nino has a 65% chance of appearing in 2015. This is a warmer sea level than average in the eastern Thai equatorial region.

Ice in the Arctic melts.Also according to NOAA, the northern polar temperature increase is double that of other regions on Earth.It could lead to a reduction in sea ice, making sea levels rise and threatening animals living in the Arctic.In a recent survey, scientists discovered 35,000 walruses stuck on Alaska's coast, due to the narrow icebergs where they live.(Photo: Wikicommons)

Prevent desertification in China.In the picture, the workers are planting large artificial forest belts (Great Green Wall) that spans nearly 4,500 km across China.This is an attempt to stop the development of the Gobi and Taklamakan deserts, while limiting the enormous dust storms they create.New Scientist said, if the forest belt exists and functions as expected, a similar green belt could be planted in Africa in the near future.(Photo: Wikicommons)

Ocean acidification.Oceans in the world are absorbing carbon dioxide, causing the pH of the seawater to change and become more acidic.This phenomenon has caused many negative impacts on aquatic resources in the world.A recent Seafood News report said the son's shell is becoming more brittle.According to a study by scientists from England, Canada and Sweden, shrimp will not retain good taste in the near future.(Photo: Wikicommons)

Responding to natural disasters.Tsunamis and many other natural disasters will not cause too much damage to humans, thanks to the development of detection systems and recovery features being built in coastal cities.In California, authorities are preparing to expand the earthquake warning system.As a result, schools, fire stations, even some private companies will receive alerts and have time to prepare.(Photo: Federal Emergency Management Agency)

Lack of water .According to the report of the US National Intelligence Council (NIC), water scarcity and water allocation problems pose great challenges to many governments in the Middle East, Africa, South Asia and the north China.(Photo: UK Department for International Development)

Prevention of climate change.In 2015, many governments and businesses began to see the need to act to reduce greenhouse gas emissions.One of the most influential figures in the world may be the deciding factor.According to Guardian, Pope Francis will give a message about climate change this year, and call for a summit between major religious leaders on the issue.(Photo: White House)
