2 . For 30 years we have been told how temperatures have been rising rapidly to unheard of levels. This is causing polar ice to melt, sea-levels to rise and has brought about a dangerous increase in extreme weather events. These intense climatic changes would likely present challenges to our society and environment.
The causes of climate change are mainly anthropogenic (人为的) in nature. Since the industrial revolution, human activities have increased the amount of greenhouse gases in the atmosphere. The increased amount of gases which absorb heat has led to more heat being kept in the atmosphere, causing global warming.
The certainty of global warming can be seen through some of the natural phenomena like the effect on crops and extreme weather conditions around the world. The most recent assessment report says that the earth’s average temperature has risen by 0. 74 degrees in the period from 1906 to 2005, and that the average temperature will continue to rise. There have also been more violent downpours, sea levels have risen and the ice at the world’s poles and on its mountains is melting. The rising sea level is flooding the low-lying countries in Asia and small islands in the Pacific. This may lead to the displacement of millions of people, loss of millions of land and consequently billions of dollars.
Troubled by the serious situation, world leaders came together for the 2015 United Nations (UN) Climate Change Conference in Paris. The climate talks led to 196 countries reaching a landmark agreement that will, for the first time, commit nearly every country to lowering planet-warming greenhouse gas emissions to address global climate change. That was certainly an encouraging step forward for our earth and mankind!
As the world leaders continue to commit themselves to monitor our sick planet, we need to continue to take small steps to heal the world. We are left with not much of a choice. If only we could just pack our bags and migrate to Mars!

3 . Although billions of locusts(蝗虫) appearing on East African countries greatly panicked farmers in 2020, they managed to see through this unexpected crisis. “Their success primarily results from a technology-driven anti-locust operation,” said Mr. Cressman, an officer in the UN Food and Agriculture Organization.
Normally, these locusts live alone across the deserts of North Africa, Southwest Asia and the Middle East. But when rains arrive, they change from a slightly brown into a deep yellow and form groups of more than 15 million insects per square mile. Such quantities of locusts can consume the equivalent amount of food in a single day as more than 13 000 people.
Locust trackers in Sudan and Eritrea find the insects by using a tablet-based program to transmit data to authorities so experts can design appropriate control strategies. But people who want to use this system might encounter a technological problem: The version of the tablets that the locust-tracking program was written for is not manufactured and newer tablets are unsuitable for the software.
Rather than rewriting the locust-tracking software for newer tablets, Mr. Cressman thought creating a simple smartphone app would make anyone collect data like an expert. He sought help from Dr. Hughes, who had already created PlantVillage to track a crop pest. Borrowing from this blueprint Dr. Hughes and his colleagues completed eLocust3m, which anyone with a smartphone can use. The app presents photos of locusts at different stages of their life cycles, which helps users diagnose what they see in the field. The locations are then automatically recorded by GPS and algorithms(算法) double check submitted photos. If necessary, pesticide-spraying aircraft will take position.
The F.A.O. estimates that this effort in East Africa has prevented the loss of agricultural products with a commercial value of $ 1.5 billion, saving the livelihood of 34 million people.

6 . Scientists say they have found high levels of small plastic particles(颗粒) in Arctic snow. A German-Swiss research team collected snow samples(样本）from the Arctic and other areas. They included northern Germany, the Bavarian and Swiss Alps, and the North Sea island of Heligoland.When the researchers examined the samples in a laboratory, they were surprised to find very high levels of microplastics.
Microplastics are very small pieces of plastic. These plastic particles are generally smaller than 5 millimeters in length. They come from the breakdown of man-made plastic products and industrial waste.
The study found the highest levels of microplastics came from the Bavarian Alps. One snow sample from the area had 154,000 microplastic particles per liter. Samples collected from the Arctic had much lower levels. However, even samples from the Arctic contained up to 14,000 particles per liter.
The study also attempted to explore how some of the material could have been carried in the atmosphere. A limited number of earlier studies did find microplastics in the air of some cities, including Paris, Tehran and Dongguan, China.
Bergmann Melanie co-wrote the report on the new study. She believes the new study clearly shows that “the majority of the microplastic in the snow comes from the air.” The new study suggests that much of the microplastic found in Europe and the Arctic comes from the atmosphere and snow.
While there is growing concern about the effect of microplastics on the environment, scientists are still studying their possible harmful effects on humans and animals. “I hope the new study will lead to more research on this issue. I think microscopic plastic particles should be included in worldwide observations of air pollution levels.We really need to know what effects microplastics have on humans, especially if inhaled with the air that we breathe.” Bergmann said.

8 . The Tokyo Summer Olympics is going green. The 5,000 medals Japan has made are more special than most.
One novel focus of the Tokyo Olympics is to be“sustainable”—to avoid using too many natural resources, so that the games are easy on the environment. As part of this goal, the organizers decided to make all of the Olympic medals out of metal recycled from old electronics.
Almost all electronics are made with small amounts of "precious metals", like gold and silver. But collecting enough of these metals to make 5,000 medals was a huge challenge. That's because the amount of metal in each device is tiny. It would take about 20,000 cell phones to get just 1 kilogram of gold.
Beginning in April 2017, the organizers placed collection boxes around the country, and asked people to turn in their old electronic devices. Soon people began to respond to the initiative, turning in smartphones, digital cameras, hand-held games, and laptops. At first, collection went slowly, but soon more and more areas began to take part. By the end, 1,621 local governments had helped out with the collection process.
Then came the job of breaking those devices down into smaller pieces. After being taken apart and sorted, the small electronics were smelted (熔炼) to get all the gold, silver, and bronze elements. This is a tricky job, which calls for careful attention and good skill. It's also dangerous, because some of the metals and other things aren't safe for people to touch or breathe.
By the end of March, 2019, the organizers had hit their targets of getting enough metal for the medals. They had collected around3xkilograms of gold, 4,100 kilograms of silver and 2,200 kilograms of bronze. And now all the 5,000 medals are available for the would-be winners.

9 . Rainbow -coloured rubbish is the colourful waste created by a Swedish city with a unique recycling system. Like many cities in Sweden, Eskilstuna has an impressive recycling record. It met the EU’ s 2020 target of recycling 50％ of waste many years ago. But almost everyone who lives here follows a strict recycling policy at home. People are expected to sort their household waste into seven separate categories, including food, textiles, cartons and metal. But what really makes the system stand out is the bright colour code.
The reason for this becomes clear at the city’ s recycling plant. The bags arrive all jumbled up because they’ re collected altogether, once a fortnight from outside people’ s houses. But thanks to those bright colours, scanners can select the bags and separate them efficiently. The food waste in green bags is processed on site into slurry(浆) to make biogas, which powers the city’ s buses. One of the benefits of this method of recycling is that there is less cross-pollution,so more of the recycled waste can actually be used to make new things.
Like the rest of Sweden, Eskilstuna is committed to sending zero waste from its citizens to landfill(垃圾堆) . Waste that cannot be recycled is incinerated at a local plant to generate electricity. This reduces reliance on fossil fuels, but does create greenhouse gases. As countries a-round the world try to improve their recycling rates, some may look to Eskilstuna as an example to follow— as long as they think they can persuade their citizens to get busy sorting at home.

10 . This season, the bushfires in Australia have burned more than 12.35 million acres of land. At least 25 people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties(伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.
Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather have made Australia more susceptible to fires and increased the length of the fire season. “The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia’s fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia,” Hausfather added on Friday.
Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures are also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.
Climate experts stress that climate change is not the only factor in the severity of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled burns and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched(派遣).
