Goal 13:Tackling(应对)Climate Change
Goal 13 calls for urgent action to fight climate change and its impact.
To address climate change, countries adopted the Paris Agreement to limit global temperature rise to well below 2 degrees Celsius. Learn more about Goal 13, and for the latest United Nations climate news, visit un. org/climatechange.
Why we need action
Climate change is now affecting every country on every continent. It is disrupting(扰乱) national economies.
The greenhouse gas emissions(排放)from human activities are driving climate change and continue to rise.
A race we can win
Affordable, scalable(可攀登的)solutions are now available to enable countries to turn to cleaner, more resilient(有弹性的)economies. The pace of change is quickening as more people are turning to renewable energy.
But climate change is a global challenge that does not respect national borders. Emissions anywhere affect people everywhere. It is an issue that requires solutions that need to be managed at the international level and it requires international cooperation to help developing countries move toward a low-carbon economy.
To address climate change, countries adopted the Paris Agreement on 12 December 2015.
A.They are now at their highest levels in history. |
B.These actions can be taken to fight climate change. |
C.The agreement entered into force less than a year later. |
D.They are also taking other measures that will reduce emissions. |
E.The passive attitude we have to the agreement as individuals can be changed. |
F.It is linked to all 16 of the other Goals of the 2030 Agenda for Sustainable Development. |
G.It is also costing people, communities and countries dearly today and even more tomorrow. |
4 . As a popular subject of study among evolutionary ecologists, three-spined stickleback (三刺鱼) is known for their different shapes, sizes, and behaviors-they can even live in both seawater and freshwater, and under a wide range of temperatures. But what makes that?
The researchers tracked six populations of the fish before and after seasonal changes to their environment, using genome sequencing. Seasonal changes result in great changes in habitat structure and balance of salt and freshwater, and only those fish able to tolerate these rapid changes survive into the next season.
“After comparing these changes, we find that they probably resemble the habitat shits experienced by stickleback populations during the past 10,000 years.” says Professor Barrett “We hope to gain insight into the genetic changes that may have resulted from natural selection long in the past.”
Remarkably, the researchers discovered the evidence of genetic changes driven by the seasonal shifts in habitats, which mirrored the differences found between long-established freshwater and saltwater populations. “These genetic changes occurred in independent populations over a single season, highlighting just how quickly the effects of natural selection can be detected,” says Professor Barrett, "The findings suggest that we may be able to use the genetic differences to predict how populations may adapt to environment."
The research emphasizes the importance of studying species in dynamic environments to gain a better understanding of how natural selection operates. In further research, they plan to investigate how repeatable the observed genetic changes are, by testing whether they show up year after year. Doing so would demonstrate their ability to reliably forecast the evolutionary future of these populations.

6 . As Covid-19 spread through the United States in the spring of 2020, previously busy cities fell silent. A new study shows that the dip in noise in the early months of the pandemic (大流行病) led to an increased abundance of birds in cities.
The flock to cities ranged “from birds like hawks and eagles all the way down to small songbirds and even hummingbirds” says Michael Schrimpf, study co-author and postdoctoral flow at the University of Manitoba's Natural Resources Institute
To see if and how birds were using now-quiet cities differently, the team of researchers analyzed more than 4.3 million bird observations of more than 80 bird species recorded on the community science app eBird. They looked at more than three years of observations taken by experienced birders before and through the first few months of the pandemic.
Scientists found significant changes in birds' migration patterns and use of urban habitats (栖息地),like bravely getting closer to usually-noisy areas like roads and airports. It was also revealed that white-crowned sparrows adapted their tune when San Francisco streets fell quiet. Bird abundance increased in cities overall, especially during spring and fall migration.
North America has lost almost a third of its birds in recent decades due to a combination of factors, including climate change, predation (捕食) by stray cats, and habitat loss, so any information scientists can obtain about how to make urban environments more bird-friendly is significant. The study's authors note that one of the most remarkable findings is that many different birds benefited from a reduction in noise, which doesn't have to be limited to pandemic lockdowns.
“There is an opportunity to adjust how we live, to slow down,” says Schrimpf. “We hope that it might be a lesson for us that we can take away in a post-pandemic world.”

9 . I’m at the salon and my hairdresser Kristi Lauren is talking rubbish. To be precise, what she tells me is pretty dumbfounding, that is, exactly how much waste her salon recycles: last year it was 1.25 tonnes. Everything from hair to shampoo bottles is recycled in innovative ways. Her waste is collected by Waste Free Systems, a social enterprise.
Lauren explains the problem, “Our colour tubes are boxed, and they can have a paper ingredient (成分) list as well as the plastic cover and the metal tube. All our product bottles. Then there' s all that cut hair, and the unused colour that would normally be washed down the sink.”
Waste Free Systems charges a fee for collecting the waste, and money raised by selling recycled materials goes to charities. Lauren, who runs an eight-chair salon, says, “It's a small price to pay. It ends up being just about $ 2 per client — we call it a green tax .”
Paul Frasca is the co-founder of Sustainable Salons,a similar service which now works with almost 1,000 hairdressing salons and beauty salons across Australia and New Zealand. Frasca says many salons are now using their green programs actively as a marketing strategy. “The environmentally aware consumer is now the most important customer on the market. So it doesn't just make environmental sense.”
Both programs are researching new ways to redirect waste. Waste Free Systems is using hair to provide nutrients for plants, while Sustainable Salons makes hair products for cleaning up oil leakage. Sustainable Salons has partnered with Dresden Vision to turn plastic shampoo bottles into frames(框架)for eyeglasses. Waste Free Systems has experimented with turning plastic bottles into 3D printing material.
