Scientists in Antarctica have recorded, for the first time, unusually warm water beneath a glacier (冰川) the size of Florida that is already melting and contributing to a _______ in sea levels.

The researchers, _______ on the Thwaites Glacier,recorded water temperatures at the base of the ice of more than 2 degrees Celsius, _______ the normal freezing point.

It is _______ how fast the glacier is deteriorating (恶化): Studies have forecast its total collapse in a century and also in a few decades. The presence of _______ water in the grounding line may support estimates at the faster range.

That is _______ because the Thwaites, along with the Pine Island Glacier, _______ as a brake (阻力) on part of the much larger West Antarctic Ice Sheet. Together, the two bigger glaciers are currently _______ ice that, if melted, would raise the world’s oceans by _______ than a meter over centuries, an amount that would put many coastal cities under water.

“Warm waters in this part of the world, as ________ as they may seem, should serve as a ________ to all of us about the potential dire (非常糟糕的) changes to the planet ________ out by climate change,” said David Holland, a lead ________ on the expedition.

While scientists may not yet be able to definitively ________ how soon glaciers like the Thwaites will melt, human-caused climate change is a key ________. The biggest predictor of “how much ice we will lose and how quickly we will lose it,” Dr. Moon said, “is human action.”

What ______ our lives most was being able to share this gift with others.

If you like to take a walk in the woods in the United States or you prefer to decorate a tree at Christmas, you should know that climate change is making both of those activities a lot more ___________.

Looking at two ___________ and economically important species - the Douglas fir and the Ponderosa pine -scientists found that fires and drought _____________ by climate change make new growth difficult, especially in low-elevation forests, according to a study published Monday in the Proceedings of the National Academy of Sciences.

Some forests in four regions in California, Colorado, the Northern Rockies and the southwestern part of the United States have crossed ''a(n) ___________ climate tipping(转折)point for post-fire tree generation, '' the study says.

Climate conditions over the past 20 years have _____________ changes that would have taken decades or even centuries to ___________ across broad regions of the country. This is leading to the sudden _____________ of trees and making these lands increasingly unsuitable for tree regeneration.

''Climate changes is _____________ our forests now, not just in some distant future. Maybe in areas where there are really _____________ seed sources, there could be some trees, but it is becoming really hard to get these trees back due to climate change, '' said study co-author Kim Davis.

The problem probably won't get any better, as climate change is making intense wildfires much more ______________. Western foresters say there used to be a fire season. But devastating and ____________ fires have become a reality all year long. In 2018, fire cost California more than $9.05 billion, according to the USA insurance commissioner, the deadliest and most destructive wildfires season in the ________________ history.

A higher number of fires and low seed availability means a high probability that these trees in these regions won't come back, Davis said. This study ______________ on the driest and hottest areas of the Western forests, but researchers will next try to focus on how much will be impacted.

____________, there are some things people can do to ease some of this problem. Forest management plans that reduce high-severity burns can help. Increasingly, forest managers are considering allowing some fires to burn under more moderate conditions, Davis said, Forest ______________can also replant trees after fire, at least in the areas where climate conditions will allow.

My photographs are the items I would definitely take or guard in case of an emergency. But what else? This was the question I asked myself as a ________ came toward us.

Unlike some friends and________, we decided to stay in our home. We didn’t have to choose what we would save by ________ it into the car, but we still had to decide what required protection by storing it in our walk-in closet. Surprisingly, few items made the cut - an obvious ________ that we had surrounded ourselves with beautiful yet unessential items. We needed ________ for the truly important things: ourselves.

Because when you hear the roar of the winds, or when something ________ hard against your windows, you don’t think of photos.You don’t worry about your big screen TV, or those paintings you’ve covered with towels to protect them, or that ________ car that you still haven’t finished paying for.

As ________ goes on outside, this is what you think: My children, are they OK? Are their impact-resistant(耐冲击的) windows working ________? Are their roofs keeping out the damage? My grandchildren, are they crying out in fear? Are they ________ as their own grandparents are? My relatives — yes, even those I try to avoid — have they ________ the worst of it? My friends, will they be forced to move somewhere else permanently? You don’t think about what you own but about what you love; what money can’t buy back.

Months and years after the hurricane, I often told people that there are two parts to ________ this kind of catastrophe: the horror of the hurricane itself and then the rebuilding that follows. The ________ together of a life, however, will take months, perhaps years.

But we will do it, ________ and as a community. Of that I have no doubt. In fact, I’ll make one more prediction. Piece by piece, item by item, we will once again collect the material possessions that decorate a home. I hate to admit this, but lessons learned ________ fear aren’t always long-lasting.
