More than 170,000 people in California are unhoused.Even as the state has poured resources into fighting against the problem，the number of people without homes has ticked upward in recent years.On the surface，the state has one key advantage for people without a reliable roof over their heads：relatively consistent and livable weather.So one of my first thoughts when I heard news of a hurricane attacking Los Angeles was just “What will happen to the city’s homeless population？”

City agencies quickly took action.As it became clear that the Los Angeles region could experience an extreme downpour and subsequent flooding，outreach teams fanned out across the river bank and dam areas across the city that have become home to a significant unhoused population，offering support to move them into shelters and motels(汽车旅馆)．

Despite that，it’s obvious that the effects of climate change will hit the most vulnerable(脆弱的) hardest.We see this globally as extreme weather events hit countries that have contributed the least to the problem.

The most notable connection between climate change and the US housing crisis is the threat extreme weather poses to unhoused people.More unhoused people are affected as climate change drives increasingly unpredictable weather.People without homes know how to respond to expected seasonal events.But events like a near-hurricane in Los Angeles or a wildfire in Maui can catch populations with limited access to information off guard.

Another link worth considering is the way in which climate change creates more homelessness and further stresses on housing systems.Hurricane Katrina，for example，displaced 800,000 people.Four years later,12,000 people remained without shelter.

Housing has been—and will continue to be—a key issue in Maui too as it recovers from the wildfire that killed more than 100 people.Maui has already had a housing crisis，the result of a high cost of living driven in large part by the tourism industry.And，now，many more are left looking for places to stay.Ashley Kelly，the chief operating officer at Hawaii’s Family Life Center，said：“Finding housing for any new clients is just not possible right now.”

1．What contributes to the increase of the unhoused population in California?

A．Its mild weather.B．Its inclusive local culture.

C．Its limited basic facilities.D．Its relaxed state policies.

2．What did outreach teams do in response to the hurricane in Los Angeles?

A．They built dams to prevent flooding.

B．They moved homeless people to safe places.

C．They sought low-cost housing from city agencies.

D．They surrounded the river bank to keep people away.

3．Which word can best describe Maui’s housing circumstances now according to Ashley Kelly?

A．Mysterious.B．Exceptional.C．Changeable.D．Difficult.

4．What is the text mainly about?

A．Ways of Americans relocating disaster-affected populations.

B．The significance of timely weather updates for the homeless.

C．The link between climate change and the housing crisis in the US.

D．Approaches of homeless Americans to dealing with natural disasters.

Today，you can buy a pair of sneakers(运动鞋) partially made from carbon dioxide pulled out of the atmosphere.But measuring the carbon-reduction benefits of making that pair of sneakers with carbon dioxide is complex.There’s the carbon dioxide that stayed in the ground，a definite carbon reduction.But what about the energy cost of cooling the carbon dioxide into liquid form and transporting it to a production facility? And what about when your kid outgrows the shoes in six months and they can’t be recycled into a new product because those systems aren’t in place yet?

Researchers are trying to help companies figure out how to account for each step in a product’s life.

As companies try to reduce their carbon footprint，many are doing life cycle assessments to measure the full carbon cost of products，from the obtaining of materials to energy use in manufacturing，from product transport to users’ behavior and end-of-life disposal(处理)．It’s an impressively complex measurement，but such bean-counting is needed to hold the planet to a livable temperature，says low-carbon systems expert Andrea Ramirez Ramirez of the Delft University of Technology in the Netherlands.

Carbon use can be reduced at many points along the production chain—by using renewable energy in the manufacturing process，for instance，or by adding atmospheric carbon dioxide to the product.But if other points along the chain like transporting consume more energy or give off more carbon dioxide，Andrea notes，the final record may show a positive rather than a negtive number.A product is carbon-reduction only when its production actually removes carbon from the environment，temporarily or permanently.

In the rush to create products that can fight climate change，however，some companies have been charged with “greenwashing”—making products appear more environmentally friendly than they really are.Examples include labeling(用标签表明) plastic garbage bags as recyclable when their whole purpose is to be thrown away；using labels such as “eco-friendly” or “100% Natural” without official certification；and claiming a better carbon footprint without acknowledging the existence of even better choices.

5．How does the author lead in the topic of the text?

A．By listing specific figures.B．By putting up questions.

C．By referring to documents.D．By offering some solutions.

6．What does Andrea think of measuring the carbon cost of products?

A．Difficult but meaningful.B．Expensive but promising.

C．Energy-saving and affordable.D．Time-consuming and valueless.
