1 . Satellites in space measure temperatures over large areas of the ocean. They are, however, less specific when it comes to measuring temperatures along the coast. However, there is a new solution.
Scientists want people who do water sports to help them gather coastal climate data. This includes surfers, divers and fishermen. The idea came from new data collected by scientists who are also surfers. The group was led by a scientist in England named Bob Brewin. The group designed a surfboard that could be their laboratory. The results show different water temperatures than what the satellites have shown.
Coastlines are important to the economy. Large amounts of people use them for business and fun. Coastlines are also important for the environment because they are home to many different plants and animals.
Brewin says satellite data alone cannot be trusted. So, his team wants volunteers to gather data during their water activities. The information the volunteers find will be used along with satellite readings. The scientists think this will result in more accurate information. “We can begin to understand how our coastal environment is responding to climate change,” Brewin said.
They want surfers to check water surfaces and divers to measure temperatures deeper in the water. The information would then go into the scientists’ database. Meanwhile, a group of scientists from Europe had another idea. The group is interested in boots that some fishermen use. These boots sense water temperatures. The scientists think the fishermen who wear those boots could be connected to a datacollection system.
Many water sports take place in areas that are important for sea life. These locations can be difficult to check, Brewin says. For example, ocean waves can ruin data-collection floats and boats. So,coastal sea surface temperature records are poor.

4 . Within a few decades, global temperatures are expected to climb to 1.5 degrees Celsius above pre-industrial levels. And that’s going to be really bad for corals, according to the latest report out from the Intergovernmental Panel on Climate Change.
So the recent IPCC report says that up to 1.5 we can expect 10 to 30 percent coral survivorship. And above that, it decreases sharply.
Andrea Grottoli is a distinguished professor at the Ohio State University. Amid the doom and gloom of the IPCC report, Grottoli has some rare good news. Corals may be more adaptable to future conditions than we thought.
Her team studied three species of coral from the island of Oahu, in Hawaii. They put them in tanks with either heat stress, more acidic water or both. And what really matters in this study is the one where both increases in temperature and ocean acidification, because that’s exactly what’s happening on reefs now.
Twenty-two months later, they assessed the winners and losers. They found that on average more than half the corals survived. Even after being punished with warmer, more acidic waters — the kind they’d face under two degrees of global warming, the corals survived. Two of the three species were actually physiologically performing normally. They were doing more than surviving. They were coping. They’d adapted. They were doing well.
The results appear in the journal Scientific Reports. Grottoli says the study provides hope. The world’s corals may be more resilient than we thought — especially since one of the Hawaiian species they studied is widespread around the planet.
But will this good news motivate world leaders to control warming? Well, corals may be able to wait just a little longer to find out.

6 . Greenland lost a record amount of ice during an extra warm 2019, with the melt massive (巨大的) enough to cover California in more than 4 feet of water, a new study said.
After two years when summer ice melt had been the smallest, the summer of 2019 broke all records with 586 billion tons of ice melting, according to a report. The loss is far more than the yearly average of 259 billion tons of ice since 2003, and it easily breaks the previous record of 511 billion tons in 2012.
“Not only is the Greenland ice sheet melting, but it’s melting at a faster and faster pace,” said study lead author Ingo Sasgen, a geoscientist at the Alfred Wegener Institute in Germany. The study also showed that there were many years in the 20th century when Greenland actually gained ice. The Greenland melt in 2019 added 0.06 inches to global sea level rise. That sounds like a tiny amount, but “in our world it’s huge — that’s astonishing,” said study coauthor Alex Gardner, a nice scientist at NASA’s Jet Propulsion Laboratory in La Canada Flintridge. With more water from other melting ice sheets and glaciers (冰川), the ocean expands and that translates into slowly rising sea levels, coastal flooding and other problems.
Though general ice-melt records in Greenland go back to 1948,scientists began making more precise records in 2003, using NASA satellites to measure the gravity of the ice sheets. It’s like put-ting the ice on a scale and weighing it as water flows off, Gardner said.
In 2017 and 2018, cooler Arctic air flowed from the open ocean into Greenland, which made the melt less severe. Several other scientists said Sasgen’s study made sense. “The fact that 2019 set an all-time record is very concerning,” one of them said.
