temperatures是什么意思？

However, we have already reached temperatures that are inlinewith other minimum-ice periods, so continued warming is likely not natural.

Global temperatures affect the rate of economic development.

Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉.

All these clothes are similar to the space Suit designs that kept astronauts comfortable in the temperatures of the moon, and are spin-offs from space technology.

As global surface temperatures increase, so does the likelihood of extreme weather.

Late November and December saw early snow and bone-chilling temperatures in much of the country, part of a year when, for the first time in two decades, record-cold days will likely turn out to have outnumbered record-warm ones.

Marine life may be affected too: El niños can reduce the rising of the cold, nutrient-rich water that supports large fish 35 populations, and the unusually warm ocean temperatures can destroy coral.

The three environmental trends—the shortage of fresh water, the loss of topsoil and the rising temperatures—are making it increasingly hard to expand the world's grain supply fast enough to keep up with demand.

Some scientists believe that the rise in carbon levels means that the Amazon and other rain forests in Asia and Africa may go from being assets in the battle against rising temperatures to liabilities.

Trees need more water as temperatures rise, but the prolonged droughts have robbed them of moisture, making whole forests easily cleared of trees and turned into farmland

The picture worsens with each round of El Nino, the unusually warm currents in the Pacific Ocean that drive up temperatures and invariably presage (预示) droughts and fires in the rain forest.

He has had his truck adapted for cold temperatures.

It melted at temperatures a bit higher than those of today

For us it'll have to operate for long periods of time in very cold temperatures.

million years, a period when global temperatures probably were not significantly higher than they are today

But this year, the Arctic is experiencing much higher temperatures.

Most forms of steel abruptly become brittle at temperatures below about -25°C unless they are mixed with other metals.

Now, though a novel type of steel has been developed that resists fractures at much lower temperatures, while retaining its strength and toughness-without the need for expensive additives.

rising temperatures and overfishing in the pristine waters around the Antarctic could see king penguin populations pushed to the brink of extinction by the end of the century, according to a new study.

Steel's fragility at low temperatures first became a major concern during the Second World War.

Then there is Antarctic's remoteness, with some mineral deposits found in windswept locations on a continent that is larger than Europe and where winter temperatures hover around minus 55 degrees Celsius.

This is troubling as climbing Arctic temperatures combined with rapid sea ice loss are creating a new type of climate feedback loop, which could accelerate Arctic warming.
