What about supply? 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.

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℉.

Wow, with the museums and restaurants in Washington, I'd be happy here no matter what the temperature.

The extensive data sources, combined with computer simulations, created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel emissions.

The researchers gathered 150 years of ocean temperature data in order to get a better picture of heat absorption from surface to seabed.

They gathered together temperature readings collected by everything from a 19th century voyage of British naval ships to modern automated ocean probes.

While sleeping, their body temperature drops, and their heart beat slows down.

it is unfair to those climate-vulnerable nationsit aims to keep temperature rise below 2 ℃ onlyit is beneficial to only fewer than 4% of countriesit burdens developed countries with the sole responsibilityThey needn't worry about the food and water they consume.

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.

The goal of keeping global temperature rise well below 2 ℃ is commendable but the emissions-reduction pledges submitted by countries leading up to the Paris talks are very unlikely to deliver on this.

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.

It was a method of refrigeration which rolls from his work in low temperature physics.

For the same reason, he placed the chairs close to each other and raised the temperature to a slightly uncomfortable level

He distinguished himself in low temperature physics.

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

"In theory," says Vallentine, "this can create a high enough temperature to generate super-heated steam.

During the Arctic winter from October to March, the average temperature in the frozen north typically hovers around minus 20degrees Celsius.

When a tree first starts growing in a certain area, it's likely that the 27 climatic envelope—the temperature, humidity, rainfall patterns and so on—suits it.

However, the last such increase in temperature took place two years ago.

Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a busin

The robots are equipped with many sensors to identify conditions of the environment, cattle and food, using thermal and vision sensors that detect changes in body temperature.

Weather conditions that drive this bizarre temperature surge have visited the Arctic before.
