1 . The number of weather-related disasters has increased by five times over the past 50 years, the latest report by the World Meteorological (气象) Organization (WMO) said on September. However, thanks to improved early warning systems and disaster management, the number of death from these hazards (危险) has been almost three times less.

According to the WMO, from 1970 to 2019, weather, climate and water hazards accounted for 50 percent of all disasters. Among the top 10 hazards that led to the largest loss of human life during this period were droughts, storms, floods and extreme temperatures. However, deaths fell from over 50, 000 in the 1970s to less than 20, 000 in the 2010s.

“Weather, climate and water extremes are increasing and will become more frequent and severe in many parts of the world as a result of climate change,” says WMO Secretary-General Petteri Taalas.

“That means more heat waves, drought and forest fires such as those we have observed recently in Europe and North America. We have more water vapor in the atmosphere, which is worsening extreme rainfall and deadly flooding. The warming of the oceans has affected the frequency and area of existence of the most intense tropical storms.”

“Economic losses are increasing as exposure increases. But behind the statistics lies a message of hope. Improved multi-hazard early warning systems have led to a significant reduction in deaths. Quite simply, we are better than ever before at saving lives,” Taalas said.

4 . In 2012, James Cameron, creator of Avatar and Titanic, became the first person to reach the Challenger Deep. When he arrived at the deepest spot on Earth at 7 miles below sea level, he spent hours mapping the region and taking photos and samples.

“As human beings, we’re drawn to absolutes—the deepest, the highest, the coldest, the farthest.” he says. “And as a storyteller and curious monkey, I just wanted to see what was there.” The answer is obvious—plastic and more. “Our so-called civilization is using the ocean as its toilet,” Cameron says. “Unless this changes, ocean ecosystems are going to continue their rapid collapse.”

Despite decades of environmental studies, the impact of plastic and other forms of pollution on oceans are not entirely understood. Initial studies appear to indicate that ingesting them-either directly or indirectly-could cause disease. Plastics can also release poisonous substances into the water, which could potentially impact animal populations.

But plastic is just one of the problems facing oceans that have yet to be fully understood. “Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which include carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic dead zones the size of countries,” Cameron says.

Oceans, like the rest of the world, are impacted by the burning of fossil fuels and the release of greenhouse gases like carbon dioxide-about 30 percent of which is absorbed by the sea. This absorption causes ocean acidification, where the pH level is altered to become more acidic. As a result, it’s harder for some creatures to form shells and skeletons and countless species at the base of the food web can struggle to survive, which, scientists say, has the potential to cause huge disruptions to entire ecosystems. Indeed, ocean acidification is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.

The effect of climate change on the world’s oceans will likely worsen in coming decades. Last June, scientists announced carbon dioxide levels had reached the highest levels since human records began. The last time carbon dioxide levels were this high was during the Pliocene era, between 3 and 5 million years ago, when global temperatures were about 4 degrees Celsius warmer than they are today. Current climate models suggest that if greenhouse gas emissions continue on their current trend, we may be on course to see 4 degrees of warming by 2100.

As a result, understanding the role oceans have on global systems is becoming more and more important.

At the age of seven, while his friends were spending their allowances on candy and toys, Jose Adolfo Quisocola was busy saving money for basic purchases. To try to get his peers (同龄人) to do the same, the boy from Peru came up with the idea of an eco- bank, the Bartselana Student Bank, which allows kids of all ages to become financially independent while also helping the environment.

Set up in 2012, the bank is the world's first bank for kids. To become a member, a kid has to bring in at least 5 kilograrms of solid waste and set a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram of recyclables on a monthly basis and observe other requirements, such as attending financial education and environmental management workshops.

The waste accumulated is sold to local recycling companies, which, thanks to Jose's efforts, pay a higher - than - market rate for everything brought in by the bank members. The money received is placed in the personal account where they collect until the savings goal is reached. The account holder can then withdraw the money, or choose to leave it and make it continue to grow for a bigger target. “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project,” Jose recalls. “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school headmaster and an assistant in my class.”

The boy's efforts paid off, and by 2013, the bank had over 200 members, who brought in one ton of recyclable waste. Today, the eco - bank, which now has the support of several local institutions, boasts ten educational centers. They are designed to teach over 3, 000 students, aged 10 to 18, to become financially independent, use their money wisely, and help the environment. Not surprisingly, Jose's efforts have earned him several national and international awards. On November 20, 2018, Jose won Children's Climate Prize, which comes with a medal and $ 5, 500 in prize money and is given to a child or youth who has accomplished an extraordinary achievement for the climate or environment.

7 . Antarctica is known for being a vast land of ice and snow, a place too cold for most life. Despite this, the continent is slowly starting to turn warm. According to the Guardian, the Antarctic has registered a new high temperature for the first time on record, prompting fears of climate instability in the world's iciest place.

On Feb 9, Brazilian researchers at Seymour Island reported a temperature of 20.75℃ on the icy continent of Antarctica. It was almost a full degree higher than the previous record of 19.8℃, taken on Signy Island (西格尼岛) in January 1982.

This record-breaking reading was taken at a monitoring station in the northern part of Antarctica. According to Brazilian soil scientist Carlos Schaefer, the temperature was documented during a 20-year-long research project. The focus of this project is to study the effect that climate change has on the permafrost(永久冻土)within the region. Permafrost is soil that stays frozen for at least two years. Although this is a first record high for Antarctica, Schaefer stressed that "We can't use this to anticipate climatic changes in the future. It's simply a signal that something different is happening in that area."

But in fact, the last high temperature reading was in the 19℃ range. These higher temperatures can cause ice and glaciers in Antarctic regions to melt. The Antarctic peninsula(半岛)---the long finger of land that stretches towards Argentina---is most dramatically affected. Scientists saw glaciers that have retreated by more than 100 meters in Discovery Bay where the snow melted in little more than a week, leaving dark exposed rock. This melted ice leads to a rise in sea levels that can threaten the safety of coastal areas. It's believed to be behind an alarming decline of more than 50 percent in chinstrap penguin(帽带企鹅) colonies, which are dependent on sea ice.

Like American writer Ernest Hemingway once said, "The Earth is a fine place and worth fighting for." We should do everything we can to help save our planet. Otherwise, it may become too hot for us to fix.

9 . At a large forest park in eastern Beijing, 11 birds on the state-level protection list were recently released.

These birds had recovered after the Beijing Wildlife Rescue and Rehabilitation Center rescued and took care of them. “We will speed up our efforts to push the establishment of district-level wildlife rescue centers to jointly guard the health of wildlife,” said Du Lianhai, director of the center.

The center was set up in 2001 and built a wildlife rescue base in the capital’s Shunyi District in 2005. Staff at the base have rescued and rehabilitated over 30,000 wild animals in total.

Wildlife protection has been strengthened in Beijing in recent years. On June 1, the city’s newly adopted regulation on wildlife protection took effect, introducing stricter and more concrete measures to protect the environment and wildlife.

For example, the regulation states clearly that Beijing bans hunting throughout the year, compared with the previous regulation which bans hunting during the periods of March to May and September to November each year. The new regulation also gives severer punishment for poachers.

After years of monitoring, data with the Beijing Gardening and Greening Bureau recently showed ecological reconstruction progress. The species and quantity of wild animals in Beijing are continuously increasing, with the number of terrestrial spinal wild animals (陆地脊椎野生动物) growing from 461 species in 1994 to more than 500. The habitat of the endangered bird has expanded from Fangshan District to the whole city, according to the bureau.

“The enforcement of the new regulation marked a new phase in Beijing’s wildlife protection work,” said Dai Mingchao, deputy director of the Beijing Gardening and Greening Bureau.

“We will step up the publicity of the regulation and raise citizens’ awareness of wildlife protection,” Dai said. “In our integrated protection of mountains, rivers, forests, farmlands, lakes and grasslands, we take into full consideration the requirements of food-chain construction, ecological corridor construction, and wildlife and their habitat protection.”

10 . The story of a voyage bearing witness to plastic pollution in the oceans. Junk Raft, based on facts, is an exciting book. Science educator and researcher Marcus Eriksen's navigational feat(航海壮举）is holding readers’ attention and interest — 88 days crossing some 4,000 kilometers of open ocean, on a raft(筏子) made of 15.000 plastic bottles wrapped in fishing nets. But it is more. Two equally fascinating story lines are made up through the written records of a series of events: Eriksen’s evolution from soldier to research director of the environmental non-profit 5 Gyres Institute, and the journey we all need to take towards a more sustainable use of plastics.

Around 15% of all the liner in our oceans is plastic, and a calculated 5 million tons of plastic waste enter the seas annually. Unavoidably, it is now present at the sea surface and on shorelines, in Arctic seas and on the sea bed at depths of 3,500 metres. Around 700 sea species are known to come into contact with pieces of waste plastic material and can be harmed or killed by taking in it or becoming twisted and caught in it.

This environmental challenge has attracted increasing scientific, media and societal attention in recent years, yet few accounts have conveyed the wider picture accessibly Junk Raft does just this while exposing our frustratingly slow progress on an issue of major importance to fisheries, tourism and, finally, the health of the world's oceans.

Eriksen lists the issues associated with the accumulation of sea plastic: the causes, consequences and potential solutions. Our single use culture is the main offender. For more than 60 years, society and industry have been producing more and more throwaway items particularly packaging. Eriksen takes the crisis into consideration together with a timeline of scientific discovery and advancement since the 1970s. Eriksen believes that the troubles of industry and policy involvement is because people lack correct consciousness of the problem.

We are brought back to the realities of life aboard the raft, with Eriksen's fellow sailor Joel Paschal. This is both fascinating and eventful, from their blow, occasionally very dangerous progress to the moments when it seems the raft will break up into pieces, littering the ocean with the waste material, Eriksen is trying so hard to fight against.

Junk Raft is filled with adventure, romance, a sense of optimism and important truths that will be needed by the thousands of groups. It serves as a reflection of the choices and journeys that each of us makes and helps us understand how plastic in the oceans is closely connected with the future of human life.
