The unusually hot water affected animals that live off the coast of Maine, which are important to the local fishing economy (经济). What’s more, it quickly became clear that the state wasn’t alone. “Heat wave events have popped up all over the ocean.” says Andrew Pershing, scientific officer at the Gulf of Maine Research Institute. “We’ve actually had three huge heat waves in the Gulf of Maine—2012, 2016 and 2018—and now we’re looking at repeat heat waves in the northern Pacific; Australia’s also had some repeat heat waves.”

That’s a big deal for coastal communities whose economies depend on fish and other seafood. Heat waves in recent years drove a lot of changes in life off the coast of the Pacific Northwest, which in turn led to disastrous seasons for fishermen. Unusually hot water supported the growth of algae that polluted the Dungeness crab (螃蟹) fishery on the West Coast, shutting it down for months. At the same time, the hot water off the coast led to continuous dry weather on land, which killed large numbers of salmon (鲑鱼) and raised the risk of wildfires.

The report suggests actions to slow ocean warming and rising and to adapt to its influences. Most importantly, the authors support what has been known for many years: Greenhouse gas emissions (排放物) are the main driver of changes in the world’s oceans, and the global economy must make a complete change to reduce those emissions.

“Even if we cut carbon emissions right now, we are still looking at 20 to 30 years of change.” Pershing explains. “That means, no matter what we do, we have to work out how we are going to adapt to these changes.”

On the other hand, darker colors, like blue and green are peaceful. The color blue can help people calm (使平静下来) down. So, a blue room can be a good place to study. However, it is easier to nod off in a blue room than in a red one. So some good ways can be used to avoid falling asleep easily.

The colors of clothes can also influence people’s feelings. Black and deep-blue clothes can produce a sense of strength and seriousness. Therefore, a person in a black suit can seem like a leader more easily than one wearing white. If a person is wearing a dark suit and a red tie, he or she may seem both powerful and energetic (精力充沛的). Perhaps this is why many business people wear dark suits with red ties. Brown and green clothes can produce a sense of confidence (自信). That means it may seem easier to trust the people wearing such colors. Therefore, many people choose to wear green or brown clothes for meetings or interviews.

Choice of color, for rooms as well as clothes, is not simply about appearance.

Connected Canadians, an Ottawa based organization provided senior citizens with tech help from volunteer mentors(导师) . To Dufton, it sounded like a great opportunity.

Emily Jones Joan is se and Tasneem Damen decided to start Connected Canadians in 2018. “Our goal is to teach senior show to search for information， ”says Jones Joan is se， “and then to become confident in their ability to pick up new technology skills on their own.”

Since much of our life is lived online, a person without the skill to deal with it can quickly feel isolated(孤独的) .Tech use has increased during COVID-19. A2020survey showed 23 percent of seniors now make video calls on their smartphones twice as many as in 2019.Seniors’use of social media is also on the rise. About 72 percent of those over 65 also said they felt comfortable using current technology.

There’s no limit on the number of sessions(时段) a senior can access. Most questions include figuring out a new phone, solving printer problems, connecting on Zoom and setting up email. The organization’s in 2021.One big reason why Connected Canadians has been so successful, adds Jones Joan is se, is that they encourage their mentors to respect and care for the senior, and not treat them like a five-year-old. Mentors are trained to imagine they are helping their elderly parents.

Kate Oakley, 70, says she started having tech trouble when she tried to move into the 21st century. She compares Connected Canadians to going to the library. “You have a knowledgeable librarian and they guide you to the right path,” says Oakley.   “They don’t do it for you, but they help you fix it yourself, so you are not always dependent on them.”
