1 . The world’s nations have promised to limit global temperature increases to 1.5 degrees over pre-industrial levels, which involves shutting down fossil fuel extraction (化石燃料开采) as quickly as possible. But despite this promise, first reached six years ago during the Paris Climate Accords, the fossil-fuel producing nations are on track to extract more than twice as much coal, oil and natural gas as would be permissible under this plan, a new United Nations report says.
To have a chance of limiting temperature increases to 1.5 degrees, production of coal needs to drop by 11% every year between 2020 and 2030. while production of oil and gas needs to drop by 4% and 3%, respectively, the report finds. Instead, production of oil and gas is set to increase, while coal production is projected to drop slightly.
The so-called production gap, the difference between countries’ climate promises and their fossil fuel production plans — hasn’t changed since the United Nations first examined it in 2019, indicating that international climate accords are still closer to theoretical promises than detailed plans.
The report looks at fossil fuel production in 15 countries — including Australia, Brazil, Canada, India, the U.S. and the United Kingdom — hat are collectively responsible for three-quarters of the world’s fossil fuel production. Most of these countries have promised to reach zero emissions by mid-century, but they are planning to increase their fossil fuel extraction until at least 2030.
So far, climate efforts from major fossil fuel extractors, including industry, have “focused on extracting fossil fuels in less-polluting ways, not on winding down production levels in line with climate goals,” the report says. While these efforts, such as developing carbon-capture (碳捕捉) technology and reducing methane leaks (甲烷泄露) are important. they fall far short of the changes science demands if global temperatures are to stay at a livable level.
To close that gap, the report urges governments to make realistic plans for winding down fossil fuel extraction, starting with state-owned companies, which arc responsible for more than half the world’s extraction of such fuels.

5 . Parrots consistently top the charts of the world’s smartest animals. A new discovery published by the Royal Society Open Science reveals to us what sets the intelligent individual monk parakeet (和尚鹦鹉) apart in a group.
Previously, it was thought that these birds introduced themselves to others with a sort of “catchphrase” that distinguished their identity. However, after running the vocalizations (发声) collected in this study through a machine learning program, a team led by Simeon Smeele, a doctoral student at Aarhus University in Denmark, found that the birds actually had “voiceprints” like humans that identify themselves in the group.
The researchers studied thousands of monk parakeet vocalizations from hundreds of birds in Barcelona across two years and ran these recordings through the program that identifies small differences in their calls.
“The voiceprint is the underlying quality of a voice that you can recognize in humans, and this is the first time that has been shown in another vocal learner,” Smeele said. For example, the voiceprint of your father is how you know it’s his voice, even if he isn’t present. “This is what I think could explain how they recognize each other, because it can be stable over very long periods of time.” he added.
“This shows that these birds also have that sort of information that they might be using in their complicated social interactions,” said Emily Du Val, Ph.D., a behavioral ecologist at Florida State University. “Research into animal communication has the potential to motivate the public into action to conserve animals. Recognizing who each other is and understanding how they interact with one another are important for human life,” she said.
This model can potentially be applied to other animals with vocal recognition like bottlenose dolphins, bat s and elephants. Future research will look into whether these voiceprints are recognized by all parakeets in the community or only a circle of close relatives.

7 . More than half the world relies on rice as a main food source. Yet the crop faces an worrying future as global warming increases the Earth’s temperature and adds to more storms, droughts and heat waves, because rice is sensitive (敏感的) to climate extremes and grows in places already experiencing many. Any disturbance to that food source can cause great problems.
The latest report from the Intergovernmental Panel on Climate Change—which brought together 234 scientists to collect recent climate studies—warned that human-caused global warming is happening at an extraordinary pace and is adding to the deadly floods, heat and droughts that we’re already witnessing. And those events result in major risks to farming.
“Higher temperatures lead to increased water loss, resulting in soil drying, increased plant stress and impacts on agriculture, especially in regions where large amounts of rainfall are not expected,” the report states.
If greenhouse gases are not reduced, about a third of global land areas are expected to suffer from at least moderate drought by the end of the century, the report concludes. Some changes like sea-level rise are already locked in.
Rice is especially sensitive to these changes. Rice often grows in ecosystems, such as deltas (三角洲), that have low sea-level and are easy to be influenced by rising seas. Any additional temperature increase could cause sea water into the filed where a healthy crop can develop, scientists say.
A 2018 study in the Archives of Agronomy and Soil Science found that an increase in the frequency and seriousness of hot weather could reduce rice outputs by up to 40% by the end of this century.
“Most of the world’s rice is currently grown in regions where existing temperature is already close to the most suitable range for rice production,” the study states. “Therefore, any further rise in temperature or short period of high temperature during sensitive growth stages will be disastrous.”

9 . Field Trip
Minnewaska State Park
May 11
This field trip will allow senior students in Mr. Corzine’s Regents Biology class to experience the beautiful Minnewaska State Park, while learning about many concepts (概念) connected to our unit on ecosystems (生态系统). Students will be going on a two-mile walk from the Peterskill entrance to the park, down to the river and then back up to a lookout point. While there they will walk through different ecosystems and learn about the history of the park.
Students should be prepared to spend time outside:
·Wear comfortable shoes and waterproof (防水的) clothing, as there is a very small possibility of light rain. The possible rain date is May 12.
·We will be walking through grassy areas, so long trousers are recommended.
·Each person should bring enough water (at least 1 liter) , as well as lunch. Minnewaska is “carry in-carry out”, so be prepared to carry whatever rubbish is produced. A small backpack (book bag) is recommended.
·Also, the weather is pretty cool at the top of the Park, so please be sure to bring warm clothing.
We will meet at the entrance in the Gym Lobby at 7:50 and will set out at 8:00 am. We plan to return at 1:45 pm. There is no cost for this trip, as the Park will be supplying the bus for us.

10 . According to a new study, human noise is a “major global pollutant” that harms a wider range of animal life than we tend to think. Published in the journal Biology Letters, the study suggests noise pollution not only harms lots of animals, but also threatens the survival of more than 100 different species.
Lots of species rely on sound for communication, for example, including many amphibians, birds, insects and mammals which use sound for vital business like finding mates or warning about predators (捕猎者). If noise pollution drowns out enough of these messages. it can threaten survival and the stability of their populations.
On the other hand, noise pollution can make it harder for some predators to find food Bats and owls rely on sound to hunt, for instance, which may not work if noise pollution drowns out the sounds of their prey like insects and mice. Even if noise pollution is mild, it might still force them to spend more time and energy searching for food, which could be enough to cause a decline.
Noise pollution is a well-known risk for whales and dolphins, but it threatens other sea animals, too. The researchers cite fish larvae, which are easily drawn to the sounds of coral reefs (珊瑚礁). This is how they find suitable habitats, but if their journey features too much noise from ships and other human sources, more fish larvae may get lost or move into wrong reefs, potentially reducing their lifespan.
Similarly, noise pollution influences the way animals migrate (迁徙), which in turn can have chain effects for ecosystems along migration routes. Some migrating birds avoid areas with noise pollution, the researchers note, which may change not only where they travel, but also where they establish long-term homes and raise their young. Many ecosystems and non-migrating species have come to depend on the arrival of migrating birds, and many others may be unprepared for their sudden absence, so this could cause a series of ecological changes.
“Noise must be considered as a global pollutant and we need to develop strategies to protect animals from noise for their livelihoods,” says Kunc, the lead author of the study.
