1 . Climate change disproportionately affects the world’s most vulnerable people, particularly poor rural communities that depend on the land for their livelihoods and coastal populations throughout the tropics. We have already seen a chain of tough suffering that results from extreme weather events, such as hurricanes, floods, droughts, wildfires, and more.
For remedies, advocates and politicians have tended to look toward cuts in fossil-fuel use or technologies to capture carbon before it enters the atmosphere—both of which are crucial. But this focus has overshadowed the most powerful and cost-efficient carbon capture technology in the world. Recent research confirms that forests are absolutely essential in reducing climate change, thanks to their ability to absorb and isolate carbon. In fact, natural climate solutions such as conservation and restoration of forests, along with improvements in land management, can help us achieve 37 percent of our climate target of limiting warming to a maximum of two degrees Celsius above preindustrial levels, even though they currently receive only 2.5 percent of public climate financing.
Forests’ power to store carbon dioxide is staggering: one tree can store an average of about 48 pounds in one year. Intact(完整的)forests could take in the CO2 emissions of some entire countries.
For this reason, policymakers and business leaders must create and enforce policies to prevent deforestation, foster, reforestation of degraded land, and promote the sustainable management of standing forests in the fight against climate change. Protecting the world’s forests ensures they can keep performing essential functions such as producing oxygen, filtering water and supporting biodiversity. Not only does the world’s entire population depend on forests to provide clean air, clean water, oxygen and medicines, but 1.6 billion people also rely on them directly for their livelihoods.
Unfortunately, a huge amount of forest continues to be converted into agricultural land to produce a handful of resource-intensive commodities - despite zero-deforestation commitments from companies and governments. So now is the time to increase forest protection and restoration. This action will also address a number of other pressing global issues. For example, in less developed, rural areas - especially in the tropics - community-based forest-management programs can forge pathways out of poverty. In the Peten region of Guatemala, for instance, community-managed forests boasted a near-zero deforestation rate from 2000 through 2013, as compared with 12 percent in nearby protected areas and buffer(缓冲)zones. These communities have built low-impact, sustainable forest-based businesses that have stimulated the economy of the region enough to fund the creation of local schools and health services. Their success is especially noticeable in a location where, outside these community-managed zones, deforestation rates have increased 20-fold.

2 . As seabird biologist Bonnie Slaton slides off a small boat and walks through high water, the brown pelicans (鹈鹕) spread their wings overhead until she reaches Raccoon Island. The narrow island is a small piece of land separating the American state of Louisiana from the Gulf of Mexico. During the seabird breeding (繁殖) season, the placer, one of the few remaining places of safety for the pelicans, is full of noise.
Twelve years ago, there were 15 low-lying islands with breeding areas for Louisiana’s state bird. However, today, only about six islands in southeastern Louisiana have brown pelican nests and the rest have disappeared underwater.
Slaton and other scientists set u cameras to observe pelican nests on the island. The cameras show that in recent years the pelicans have faced some natural disasters. The main killer of them is flooding, which can wash away all the nests, as happened in April 2021. The disappearing islands are the location of a story of successful conservation. For many years, scientists have worked to bring the pelicans beck from tally dying off.
Mike Carloss is a state wildlife biologist in Louisiana. He said he never saw brown pelicans as a child in the 1960s. Their populations had been killed by the use of DDT, a kind of farm chemical. It thinned eggshells and prevented pelicans from giving birth to young birds. The beloved birds were completely gone from Louisiana, only appearing on the state flag. But a long-running effort to save them led to the birds’ return. After DDT was stopped in the U.S. in 1972, biologists brought young pelicans from nearby Florida to let them inhabit empty islands across the Gull of Mexico again. More than 1,200 pelicans have been set free in southeastern Louisiana over 13 years.
The brown pelicans can live more than 20 years. So, the final effect of disappearing breeding areas is uncertain and it will sill take time to become clear. And the future for pelicans is uncertain on the islands.

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.
5 . Burning coal for energy adds planet-warning carbon dioxide (CO2) to Earth’s atmosphere. As the planet heats up, experts warn that simply cutting greenhouse gas emissions (排放) will not be enough to avoid global warming. CO2 must also be removed from the atmosphere.
Existing experimental machines that pull CO2 directly from the air are too expensive to be widely used. But a new effective technology to remove CO2 already exists. It is not expensive and easy. It is forests. Planting trees and watching forests are effective ways to clean the air.
Forests used to cover large areas of the Appalachian Mountains in the eastern United States. In the state of West Virginia, coal mining let the land there bare, without trees. Over the years, coal mining and cutting forests took over 90 percent of the red spruce (云杉) forests.
Chris Barton works for the University of Kentucky. He started a group called Green Forests Work, aiming to put trees back on the roughly 400,000 hectares of land.
However, Barton explains the land has problems. “If you planted trees on these places, they just didn’t grow. The ground was too hard. Water didn’t infiltrate (渗透). The trees can’t root. Oxygen can’t circulate in those environments.” Using heavy equipment, workers tear the ground. In this way, the trees put down roots.
Barton says not everyone believes the solution is a good idea. “We’ve had a lot of doubtful look at us twice from people. But after we do it, there’s no question that it was the right thing to do.” And it has worked. Forests are coming back to the grounds.
Scientists say that, in West Virginia alone, restoring red spruce forests to the area could send what is equal to 56 million barrels (桶) of oil into the ground. But it will take time — a long time. Around the world, experts say, nature offers powerful tools to fight climate change. But patience is needed. Nature works, but slowly, in its own time.

6 . As the effects of climate change become more disastrous, well-known research institutions and government agencies are focusing new money and attention on an idea: artificially cooling the planet, in the hopes of buying humanity more time to cut greenhouse gas emissions.
That strategy, called solar climate intervention (干预) or solar geoengineering, involves reflecting more of the sun’s energy back into space — abruptly reducing global temperatures in a way that imitates the effects of ash clouds flowing out from the volcanic eruptions. The idea has been considered as a dangerous and fancied solution, one that would encourage people to keep burning fossil fuels while exposing the planet to unexpected and potentially threatening side effects, producing more destructive hurricanes, wildfires floods and other disasters.
But. as global warming continues, producing more destructive hurricanes, wildfires floods and other disasters, some researchers and policy experts say that concerns about geoengineering should be outweighed by the imperative to better understand it, in case the consequence of climate change become so terrible that the world can’t wait for better solutions.
One way to cool the earth is by injecting aerosols (气溶胶) into the upper layer of the atmosphere. where those particles reflect sunlight away from the earth. That process works, according to Douglas MacMartin, a researcher at Cornell University.
“We know with 100% certainty that we can cool the planet,” he said in an interview. What’s still unclear, he added, is what happens next. Temperature, MacMartin said, is an indicator for a lot of climate effects. “What does it do to the strength of hurricanes?” he asked, “What does it do to agriculture production? What does it do to the risk of forest fires?”
Another institution funded by the National Science Foundation will analyze hundreds of simulations of aerosol injection, testing the effects on weather extremes around the world. One goal of the research is to look for a sweet spot: the amount of artificial cooling that can reduce extreme weather events without causing broader changes in regional rainfall patterns or similar impacts.

7 . Not long ago, Egypt marked the 150th anniversary of the opening of the Suez Canal. The canal connects the Mediterranean Sea to the Red Sea and the Indian Ocean. It helped speed world trade between the East and the West. But the man-made waterway has also helped speed the rise of other things, such as invasive(入侵的)non-native species (物种). Scientists say the invasive creatures have damaged the Mediterranean’s environment and caused native species to disappear.
The number of non-native creatures has risen since the Suez Canal was widened in 2015. The “New Suez Canal” has raised concerns in Europe and brought disagreement from many Mediterranean countries. Bella Galil is an Israeli biologist who has studied the Mediterranean for over 30 years. She says much of the ecological(生态的)damage cannot be repaired. She said urgent action is needed to ease the effects of the invasive fish and other sea life.
Galil works at Tel Aviv University’s Steinhardt Museum of Natural History. She noted that the widening and deepening of the Suez Canal has created a “moving aquarium” of species. These creatures could make coastal waters almost unusable for human beings. Galil believes the number of invasive species has reached 400. That is twice the number 30 years ago. She said this is a “historic example of the dangers of unintended consequences.”
Israel is now dealing with huge numbers of poisonous(有毒的) jellyfish that affect coastal power centers and keep people from visiting the seashore. Other poisonous species, such as the lionfish and silver-cheeked toadfish, are also appearing.
Galil said the problems of invasive species can be compared to those of climate change, pollution and over-fishing. She argues that the new species have caused a major “restructuring” of the environment. This has endangered native species.
Some experts have suggested that increasing salt levels in the canal itself could create a barrier(障碍物) that would keep invasive species out.
