60% of all animals have been killed since the 1970s.Because of global temperature change, the Earth's oceans and land have always warmed; animals and eco-systems can't keep up with the new rate of change, which forces some animals and plants into extinction.Unless we change our habits, ...
D A new study says that no matter how much the world cuts back on greenhouse gases, a large and importan part of ice of Antarctica(南极洲) is expected to disappear.Researchers used computer models to expect the future melting (融化) of protective ice around Antarctica's Amundsen Se a in...
The past seven years of the record really stand out as much warmer than anything that has come before. This can be seen in the figure below from Berkeley Earth. Each shaded curve represents the annual average temperature for that year. The further that curve is to the right, the warmer it...
we mean really long-term. Even a few hundred years is pretty short-term when it comes to climate. In fact, changes in climate sometimes take tens of thousands of years. That means if you happen to have a winter that isn't as cold as usual, with not very much snow -- or even two...
If it were not for the oceans, the planet would be much hotter due to climate change. But in the last 40 years, the ocean has absorbed about 90% of the warming caused by heat-trapping greenhouse gas emissions. Much of this ocean heat is contained near the ...
are ocean temperatures. Historically, El Niño Southern Oscillation (ENSO) events have resulted in warmer-than-normal coastal waters from California to Peru, but more recently, a new warming phenomenon has been identified across the world's oceans. Marine heatwaves are created by a regional build...
Traveling at 80% the speed of light to Gilese 581's planet, it would take us about 96 years to reach the planet. How much time would have elapsed on Earth?How much has the Earth warmed between: i) 1880 and 2012 ii) 1970 and 2012 Provide the answer in both degrees ...
Although the amounts being released by human activities are not as great as the amounts of CO2, nitrous oxide absorbs much more energy than CO2 (about 270 times as much). For this reason, efforts to curb greenhouse gas emissions have focused on N2O as well [Source: Soil Conservation ...
we now knowhow much the world has warmed, how rapidly mountain glaciers andArctic ice are retreating, how much and whereprecipitation is changing, how much soil moisture is reducingandwhat it would take to avoid significant global climate disruption. Long-term, depoliticized investments in this ki...
The naturally occurring phenomenon which covered the lower atmosphere of the earth and warmed it is known as the greenhouse effect. The... Learn more about this topic: Global Warming: Atmospheric Causes and Effect on Climate from Chapter 12/ Lesson 4 ...
