Last month, our school launched a campaign which intention was to promote environmental protection. The campaign last for one week. Firstly, there was a photo display to show the seriously pollution caused by human activities. Secondly, there was a lecture on many small step that we could take in our daily life protect the environment. For example, taking the bus and using the bike-sharing system would be a good way. Last but not the least, we students were encouraging to decorate our classrooms with recycled materials. Through the campaign, they have benefited a lot. We realize that it is our responsible to leave a better, cleaner and healthier planet for future generations.

4 . Asia’s mountain glaciers (冰川) will lose at least a third of their mass through global warming by the century’s end, with serious consequences for millions of people who rely on them for fresh water, researchers have said. The high mountains of Asia consist of a geographical region surrounding the Tibetan Plateau, holding the biggest store of frozen water outside the poles. It feeds many of the world’s great rivers, including the Ganges, the Indus and the Yarlung Zangbo River, on which hundreds of millions of people depend.

Nearly 200 nations adopted the Paris Agreement in 2015, which sets the goal of limiting warming to a level of “well below” 2°C, while “pursuing efforts” to achieve a lower ceiling of 1.5°C. Earth’s surface has already warmed by about 1°C, according to scientists.

The Asian high mountains, the new study said, were already warming more rapidly than the global average. A global temperature rise of 1.5°C would mean an average increase in the region of about 2.1°C, with differences between mountain ranges — all of which will warm by more than 1.5°C. The Hindu Kush mountain range would warm by about 2.3°C and the eastern Himalaya Mountains by 1.9°C, the study forecast.

“Even if temperatures stabilize at their current level, (glacier) mass loss will continue for decades to come,” the researchers added. “For the high mountain glaciers to survive, it is vital to reduce the global temperature increase to the lowest possible level.”

A study in July in the journal Nature Climate Change said there was only a 5% chance of holding global warming under 2°C. For 1.5°C, the chance was about 1%. On current trends, some experts project Earth is on track to warm by about 3°C.
