Global surface temperature (GST) is the average temperature of Earth's surface. Scientists take the temperature of the surface of the sea and the... Learn more about this topic: What is Global Warming? - Definition & Lesson for Kids
What cities are at sea level? What is the temperature at sea level? What is the lowest point below sea level? What are the levels of the pelagic zone? How high did sea level rise during the 20th century? How much has sea level risen since 1990?
Jetting into the Arctic Ocean, Alaska's Point Barrow is the northernmost tip of the United States. Of course, Alaska's not the only place that penetrates the Arctic Circle. Large portions of Canada, Russia, Norway, Finland and Sweden also fall within the Arctic Circle's borders. So does ...

Greenland) could melt, dramatically increasing sea levels. With warmer temperatures, there would be the expansion of the water in the ocean, further contributing to a rise in mean sea level. Sea level rise is also known as submergence since land above current mean sea level is drowned or ...
The darker red colors indicate an in increase in sea surface temperature. Coral bleaching is caused by increasing ocean temperatures. As water temperatures rise, it causes corals to expel their zooxanthellae, leaving behind a bone-white shell and depriving the coral of its main food source. “...
A rise of just 1 to 2 degrees can force the corals to drive out the algae (水藻). Then the corals turn white in a process called “bleaching”. Corals can recover from short-term bleaching, but long-term bleaching can cause permanent damage. In 1998, when sea surface temperatures were ...
Over 60 years ago, Sir Gilbert Walker, a British scientist, discovered a connection between surface pressure readings at weather stations on the eastern and western sides of the Pacific. He noted that a rise in atmospheric pressure in the eastern Pacific [#highlight6]is usually accompanied[/...
The idea, first floated by the British physicist John Latham in 1990, is that spraying tiny salt particles from seawater toward low-lying clouds above the sea could form additional droplets, increasing the surface area—and thus reflectivity—of the clouds. The team is currently raising fun...
Ice cores are tubes of ice taken from deep below the surface of the ice today. Scientists can analyse the bubbles in each layer to calculate how much carbon dioxide they contain. Rising sea levels also tell us that the climate is warming up, and this isn't just due to melting ice caps...
