In Kenya’s countryside, people are facing one of the most serious droughts in memory. Some regions have been without rain for two years, and more than half the crops and most of the farm animals have died. Up to 4 million people may require food aid in the coming months.

Kenya isn’t the only country to suffer the fallout from climate change in recent years. Countries least responsible for the climate crisis are most vulnerable to its effects. In South Asia, Bangladesh already spends $2 billion each year on climate-related damage, according to a report from the International Institute for Environment and Development. A dozen island nations are at risk of disappearing entirely.

The international community has realized the urgency. In 2010, the United Nations created an institution, the Green Climate Fund, or GCF, to support developing countries that aren’t historically responsible for causing the climate crisis to cut their emissions (排放物) and deal with climate impacts.

However, the UN climate fund now has warned that carbon-cutting projects in developing countries would have to be cut without more money coming in.

Campaigners have blamed the United States—one of the GCF’s founders—for the potential cuts. “If the GCF needs to limit its operations in the near future due to lack of funding, it’s hard to find any single country more at fault than the US,” Action Aid’s policy director Brandon Wu told Climate Home News.

In 2014, then-US president Barack Obama promised the GCF $3 billion but gave only $1 billion before the end of his term. His successor, Donald Trump, didn’t give any money to the fund and, so far, neither has President Joe Biden. The US owe s the fund $ 2 billion.

Last year, 46 climate and green groups signed a letter that urged the White House to give the $2 billion to the GCF. The climate and green groups also asked the administration to commit an additional $6 billion to bring the US in step with other donor countries.

In 2019,1 3 countries—mostly in Europe but including South Korea and New Zealand—announced a doubling or more of their contributions to the GCF to help fun d green projects for 2020-23.

High sea-surface temperatures are causing long-term damage to coral reefs (珊瑚礁). Corals are dying. The IPCC (政府间气候变化专门委员会) projects that up to 90 percent of coral reefs could disappear if global warming reaches 1.5℃. Another reason corals are in trouble is because of ocean acidification. Higher carbon dioxide levels have shift ed the chemistry of the ocean, making it more acidic, and corals and sea creatures have trouble growing in acidic conditions.

When ocean water warms, it expands in volume. This is a major cause of the rise in sea levels, along with the water added to the ocean by the melting of land-based glaciers (冰川). The sea level has risen by an average of 20 centimeters since the late 19th century, and the research by scientists studying the last 25 years of satellite data found that the ocean water is rising faster and faster. If it continues at its current rate, the rise in sea level by 2100 will be more than double the current estimates. Sea level rise leads to the destruction of coastal wetlands, flooding and damage to water ecosystems.

Temperature and precipitation (沉淀) are key elements of climate. A warmer climate means that more water rises from both the land and ocean, and a warmer atmosphere holds more of that water. Scientists have noticed that there are more heavy rainfall events. Additionally, higher water temperature in streams, lakes, and rivers lead to lower levels of dissolved oxygen in the water, which impacts the survival and populations of fish and other sea life.

Especially troubling are the extreme weather events that are happening more often around the world. Hurricanes are ramping up in intensity, particularly in North Atlantic. The year 2017 was a busy one for Atlantic hurricanes. Meanwhile, in the western United States, the state of California has had record-setting drought conditions, which began in 2012.

But what happens when the batteries are used up and have to be replaced? Many of them end up in the trash where the chemicals can get into the soil causing environmental damage. In fact in Australia, 97 percent of single-use batteries end up in landfills.

While batteries can be traditionally recycled, this involves using high heat to melt the metals that can then be reused. The method doesn’t allow for the repurposing of other elements that actually have to be mined. It is allowing valuable resources to go to waste.

Envirostream — a part of the battery recycling company Lithium Australia — came up with an innovative way to turn old batteries into plant fertilizer. While some of the chemicals in batteries are poisonous, the company engineered a new method that takes the micronutrients like zinc and manganese oxide out of the alkaline (碱性的) batteries by crushing (碎) them and removing the poisonous elements. Lithium Australia has tried to find a solution for these waste batteries that is better for the environment and creates better value.

The company began field trials in 2020, testing a fertilizer supplement made from the upcycled batteries on wheat and found that it compared well to commercial fertilizers. After that, they tested the fertilizer in soil that was lacking in the minerals. Now, the fertilizer has been successfully applied to growing tomatoes, avocados, and cotton crops.

Going from powering remotes to powering plants completes a cycle for elements that come from the earth to then go back to the earth. Recycling batteries for useful components and keeping them out of landfills is good for the planet.

【推荐2】One of the biggest challenges that traditional educators face is how to unlock students’ love of learning. Once students overcome their fear or unwillingness, they will be on the track of becoming motivated learners.

In order to help students discover the joy in learning, some teachers are turning to a simple but effective strategy called gamification-using game-related elements such as activities and rewards to promote students’ engagement in class. With an origin in educational psychology, this approach is designed to reach students by making the learning process funny and interesting.

What’s more, researches show that gamification can also make assignments less stressful. Without too much pressure, students will associate learning with curiosity and joy. Accordingly, they feel like continuing the journey because positive feelings have boosted their confidence.

But like any other strategies, gamification has its drawbacks when used incorrectly. It is very likely that some students only focus on winning rewards but have no interest in understanding concepts or learning new skills-exactly the opposite of the desired outcome. To avoid this, teachers can help prevent students from becoming wrongly motivated by choosing suitable rewards. Instead of class parties or snacks, try rewards that help students develop a passion for academic subjects.

For example, have students earn points towards a class field trip by behaving and doing their assignments, or pair subjects that a student dislikes with fun books or activities to encourage motivation. That way, they associate fun with reading, math, or other skills. More examples include competing on a leader-board, holding a talent show, or playing other team-building games. All activities and rewards need to be carefully selected and well arranged.

If you’re having a hard time getting your class interested in learning, talk with them together or individually about what motivates them and include it into your student engagement strategies.
