1 . A recent global study, which surveyed 10,000 young people from 10 countries, showed that nearly 60 percent of them were extremely worried about the future state of the planet. The report, which was published in The Lancet, also showed that nearly half of the respondents said that such distress affected them daily, and three quarters agreed with the statement that “the future is frightening.” This, along with many other studies, shows clearly that climate change is not just a threat to the environment that we inhabit. It also poses a very real threat to our emotional well-being. Psychologists have categorized these feelings of grief and worry about the current climate emergency, a common occurrence among youth today, under the label of “eco-anxiety”.
Eco-anxiety doesn’t just affect young people. It also affects researchers who work in climate and ecological science, burdened by the reality depicted by their findings, and it affects the most economically marginalized (边缘化的) across the globe, who bear the damaging impacts of climate breakdown.
In 2024, eco-anxiety will rise to become one of the leading causes of mental health problems. The reasons are obvious. Scientists estimate that the world is likely to breach safe limits of temperature rise above pre-industrial levels for the first time by 2027.
In recent years, we’ve seen wildfires tear through Canada and Greece, and summer floods ruin regions in Pakistan that are home to nearly 33 million people. Studies have shown that those impacted by air pollution and rising temperatures are more likely to experience psychological distress.
To make matters worse, facing climate crisis, our political class is not offering strong leadership. The COP28 conference in Dubai will be headed by an oil and gas company executive. In the UK, the government is backtracking on its green commitments.
Fortunately, greater levels of eco-anxiety will also offer an avenue for resolving the climate crisis directly. According to Caroline Hickman, a researcher on eco-anxiety from the University of Bath, anyone experiencing eco-anxiety is displaying entirely natural and rational reactions to the climate crisis. This is why, in 2024, we will also see more people around the world join the fight for climate justice and seek jobs that prioritize environmental sustainability. Campaigners will put increased pressure on fossil fuel industries and the governments to rapidly abandon the usage of polluting coal, oil, and gas.
It’s now clear that not only are these industries the main causes for the climate crisis, they are also responsible for the mental health crisis, which is starting to affect most of us. Eco-anxiety is not something we will defeat with therapy, but something we will tackle by taking action.

3 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing.” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
What is the main purpose of the passage?
| A．To assess the consequences of ocean colour changes. |
| B．To analyse the composition of the ocean food chain. |

COP26,
6 . The scientists behind a new database of more than 400 extreme weather attribution (归因) studies have performed an essential service. This piece of work, drawing together every study of this type, ought to create a greater sense of urgency around policymaking and campaigning. It shows that intense heatwaves, hurricanes, and floods have all been made far more likely by greenhouse gas emissions. And it spells out the alarming unpredictability as well as the extent of global heating’s consequences.
Until the early 2000s, when the first attribution studies were published, it was harder to link CO2 in the atmosphere with global heating’s sensible effects. Thanks to a growing body of research, now we know. The last summer’s record-breaking “heat dome”(热穹顶) across the globe would have been almost impossible without human-caused climate change.
“Beauty is truth, truth beauty,” wrote the poet John Keats just over 200 years ago. When it comes to climate, truth can feel closer to terror these days. But scientists are right to insist that the reality must be faced. Indeed, this is the only way to avoid the most disastrous outcomes. In a new book, Hothouse Earth, Prof Bill McGuire argues that we have reached a stage when minimising dangers should be regarded as “climate appeasement”.
Like the historical responsibility for carbon emissions, attitudes and experiences in the present crisis are unevenly and unjustly shared out. Billions of people around the world, and above all in the global south, are caught up day-to-day in a struggle for survival. This doesn’t mean they don’t recognise global heating; subsistence (勉强维持生活) farmers and fishers are more directly exposed to environmental damage than anyone else. But western governments, businesses and people who are relatively sheltered from global heating’s worst effects should recognise this as the privilege that it is. With this year’s Climate Change Conference fast approaching, western governments must follow through on their promises of climate finance to enable a green transition in the developing world.
The purpose of attribution science is not simply to warn the world about what is happening, but to aid preparations for what has not happened yet. The most alarming global trend, apart from still-rising emissions that mean we are on course for 2. 5°C of heating, is the unexpected speed with which it is already causing chaos. Given what we now know about the impact of 1°C of warming, it is no exaggeration to say that this trend is disastrous.
But alternatives exist, and insisting on this point has never been more important. The alarming findings of attribution scientists can give rise to desperation-but must not be allowed to end determination and hope.

Climate change influences how organisms live and function in their environment. Investigating how organisms adapt is essential for accurately predicting their survival, and tracking genomic(基因组的) changes helps researchers determine the lasting effects of the changing environment. Copepods, a dominant coastal species, are particularly useful for studying genetic changes in response to shifting marine environments. By studying copepods, researchers can get an idea of how the ocean food chain might react to changes in the Earth’s climate.
Tracking a copepod’s evolving genome in the wild, however, can be time-consuming and laborious. To circumvent this challenge, Pespeni and her team used an evolve-and-resequence approach in the lab. They exposed a copepod population to three stressors—water warming, acidification via high CO₂ levels, and combinations of the two ocean warming and acidification (OWA) conditions in the laboratory, and tracked their adaptations to these conditions over 25generations. Previously, they tracked reproductive fitness traits such as egg-hatching success under these conditions. They found that the fitness of the population exposed to OWA conditions initially decreased, but then adapted to the stressors over several generations.
In the current study, the researchers sequenced the genomes of animals in each experimental group at generation 0 and 25 to quantify how allele (等位基因) frequencies changed in response to experimental selective pressures. The researchers found adaptive alleles related to development were unique to the multiple stressor experiment, providing a possible explanation for the observed selection of hatching success.
“We showed that the warming alone was a much strong er selective pressure than CO₂. But when you combine them, you get a unique synergy. So, it’s not just one plus one equals two; it’s one plus one equals something totally different,” said Pespeni. Whereas previous studies observed the effects of single stressors on evolving organisms, Pespeni’s study demonstrated that multiple stressors result in a unique response to selection in a non-additive manner. This is important because human-induced environmental changes are multifaceted(多方面的), and additional stressors are still needed to further mimic natural environmental changes, and this study reveals the complexity of the genomic adaptive response.
According to Morgan Kelly, a professor who was not involved in the study, the insights presented by the researchers in this study call into question the previous single stressor studies and will influence future experimental design. “There’s this big question of the role that evolutionary change will play in response to climate change, and the way the researchers integrate genomic information is the best of its kind in the world of marine experimental evolution,” said Kelly.
According to Pespeni, there is reason to maintain hope in the face of climate change because her work revealed that the copepods eventually fully regained their ability to reproduce following the combined environmental changes.

10 . Climate experts are having a debate: they are asking whether the UK should focus more on adapting to climate change or trying to prevent it.
David Frost holds that preventing climate change is no longer an option, given the extent to which the Earth now appears certain to heat up. Despite the many policies which attempt to stop climate change, it now seems unavoidable that the world will pass the 1.5℃ or 2℃ increases in average global temperature that are likely to induce large changes in the climate.
David Frost is right in that our economies are growing so much slower than we had anticipated. Our emissions can drop if we reduce emissions per unit of GDP we create—but they can also drop if the GDP is lower. Lower growth means it is more feasible (可行的) for us to achieve targets such as Net Zero, but it also makes it less environmentally urgent to achieve those targets so soon, because we are and have been emitting a lot less carbon than we had anticipated.
The UK authority finds the debate about adaptation difficult. Partly, it is because some activists claim that adaptation is not feasible. They say that climate change will end human civilization, potentially leading to the entire extinction of the human race.
However, the mainstream view of many scientists and economists, who work on climate change, is that global warming could lead to large changes in our environment. Significant parts of the world currently heavily populated could become effectively uninhabitable while other parts currently unsuitable for high-density human habitation would become more habitable. Meanwhile, at higher temperatures both climate and weather are likely to become more volatile—including increased frequency of storms, flooding and other weather events.
These would be significant changes, but it would be perfectly feasible for humans to adapt to them. The issue is not whether adapting would be technically feasible, but whether it would be desirable either in ethical or practical terms. Are we willing to accept a materially warmer world, with humans living in different parts of it? Are we willing to accept the possible extinctions of certain species and the greater flourishing of those currently less successful and of new species yet to evolve? Are we willing to accept the consequences of a large shift in the patterns of human habitation across the world?
It is by no means clear on what basis we ought to ethnically privilege the plants and animals that flourish under today’s climate over those that would flourish under a warmer, more volatile climate. However, adaptation will be feasible and is a necessity given the extent to which warming is now unavoidable. Slower GDP growth and thus slower climate change ought to make greater efforts at adaptation more attractive.
