1 . Earth’s oceans are changing color and climate breakdown is probably to blame, according to a research. The deep blue sea is actually becoming steadily greener over time, according to the study, with areas in the low latitudes(纬度)near the equator especially affected.

“The reason why we care about this is not that we care about the color, but that the color is a reflection of the changes in the state of the ecosystem,” said BB Cael, a scientist and author of the study published in Nature.

The previous research focused on changes in the greenness of the ocean to learn about trends in the changing climate. But Cael’s team pored over 20 years of observations by NASA’s Modis-Aqua satellite, a comprehensive database, and looked for patterns of change in the ocean’s color through a fuller color spectrum(色谱)including red and blue.

The changes have been detected in over 56% of the world’s oceans. In most areas there’s a clear “greening effect”, Cael said, but he added that there are also places where red or blue colorings are rising or falling. “These are not massive ecosystem-destroying changes. They may be mild,” said Cael. “But this gives us an additional piece of evidence that human activity is likely affecting large parts of the global biosphere(生物圈)in a way that we haven’t been able to understand. ”

Although this discovery firmly documents another consequence of a changing climate, what is not yet clear is how strong these changes are and what is happening inside the ocean to cause them, according to Michael J Behrenfeld, a researcher of ocean productivity, who was not involved in the research.

NASA will be launching an advanced satellite mission in January 2024 called Pace which will also measure hundreds of colors in the ocean instead of a handful, progressing studies like these further. “Making more meaningful inferences about what the changes actually are is definitely a big next step,” said Cael.

Tianwen-1, China’s first independent interplanetary mission (星际任务),    1    (reach) Mars within days of two other major missions: the United Arab Emirates’ Hope satellite and NASA’s Perseverance rover (探测器), after it had travelled 292 million miles from Earth. All three took advantage of a    2    (particular) suitable launch window when objects launched from Earth would have a    3    (short) and more efficient path to Mars. But all three missions will have plenty to do on the Red Planet.

Various space missions, the European Space Agency’s Mars Express and several of NASA’ s Mars lovers    4    (include), have found possible evidence of water on or under the    5    (planet) surface. But bothTianwen-1    6    the as-yet-unnamed rover will use radar devices to search for even better evidence of pockets of water on Mars.

That’s important, scientists say, because plenty of evidence points to Mars having an    7    (able) to support life at some point in its history: In some areas, it is likely to host liquid water. Tianwen-1’s intended landing site at the Utopia Planitia crater may still host an underground deposit (沉积层),    8    contains as much water as Lake Superior. On a broad scale, researchers around the globe hope    9    (use) information from any of the new Mars missions to look into how a planet with liquid water, organic maternal and an energy source can transform itself    10    a dry, dusty desert place.
