Earth warming at record rate, researchers say

The Earth’s warming rate hit a record high last year, though the data did not show climate change is significantly accelerating, according to research published Tuesday.

According to the “Indicators of Global Climate Change” report, last year’s rate of warming reached 0.47 degrees Fahrenheit, or 0.26 degrees Celsius, per decade, up from 0.45 degrees Fahrenheit, or 0.25 Celsius.

While not a major jump, study lead author Piers Forster, a Leeds University climate scientist, noted to The Associated Press that it makes last year’s rate the highest ever.

The group of 57 scientists pointed to the combination of greenhouse gas emissions and decline in aerosols as the main contributors to this high rate of warming, while noting greenhouse gas emissions have not risen past prepandemic levels.

“If you look at this world accelerating or going through a big tipping point, things aren’t doing that,” Forster told the AP. “Things are increasing in temperature and getting worse in sort of exactly the way we predicted.”

2023 marked the hottest year ever recorded, with average land and ocean temperatures reaching 2.12 degrees Fahrenheit above the 20th century average, the National Oceanic Atmospheric Administration confirmed earlier this year.

Under the Paris Agreement in 2015, the world agreed to try to limit future warming to a threshold of 1.5 degrees Celsius — 2.7 degrees Fahrenheit — though this is for long-term temperature measurements rather than a single month or year.

If the Earth continues to produce the same amount of carbon dioxide emissions as the start of this year, the report predicted the temperature will break the Paris Agreement threshold in less than five years.

Tuesday’s report, published in the journal Earth System Science Data, said 2023 was 1.43 degrees Celsius warmer than the 1850 to 1900 average, with 1.21 degrees of that contributed to by human activity. The remainder of the temperature change can be pinned on natural factors such as El Niño.

Over a 10-year period, the world’s temperature increased by about 2.14 degrees Fahrenheit — 1.19 degrees Celsius — since preindustrial times.

El Niño conditions arrived early in June last year, ahead of its typical time frame in late summer or early fall. Forecasters are predicting El Niño will likely get warmer and cause even higher temperatures this year.

The coalition of scientists behind the Tuesday report was created to provide annual scientific updates between every seven-to-eight-year major United Nations scientific assessment, the AP noted.

  • Philippine town cleans up beach in exchange for rice

    STORY: :: Mabini, PhilippinesPlastic waste litters the shores of this resort town near Manila, the Philippines' sprawling capital.This coastal cleanup crew is trying to hold back the steady flood of waste.But each sack of they gather doesn't go unrewarded. They get a two-pound bag of rice in exchange, enough for a small family's needs.:: This Earth Green campaigners say the exchange can educate the community about why protecting the environment is so critical, all while keeping the shores clean, and as inflation bites, keeping people here, like Janeth Aceveda, afloat. "The exchange is a huge help for us because in a month I need four and a half sacks of rice, but now all I have to buy is two sacks, which is a huge help in saving money. It also helps the environment and it shows when our surroundings are clean." Mabini in Batangas province is a world-class scuba diving destination, known for its vibrant corals and marine biodiversity. But a rising tide of plastic pollution is posing an increasing threat to marine life. Organizer Giulio Endaya has witnessed the harm first hand. :: Giulio Endaya, Exchange organizer"I've seen sea turtles entangled in nets and other types of plastics. They've been known to eat straws and plastic bags, and the fish also eat microplastics that have been, you know, broken down in the shore. And recently we've been finding more and more microplastics even in fish that we eat, so it's also harmful to us." To untangle the problem, Endaya and his group of volunteers spearheaded the ‘Plastic Palit Bigas’– or ‘plastic in exchange for rice’– program. The project is funded by donations from individuals and small companies that advocate for marine conservation. Through the exchange, Mabini volunteers can turn in sacks of litter, regardless of weight, for a kilogram– or 2.2 pounds– of rice. Volunteer Raymond Basit says it’s been a potent incentive. "It helps a lot because people now have an urge, because of poverty and especially during these times, the price of goods is so high. Now during their free time they can clean, and they push themselves to clean because they get something in return, which is a big help for them." An updated 2022 University of Oxford report found that The Philippines accounts for 36% of the total global input of plastic waste into the ocean, more than any other country. The plastic for rice exchange aims to change that. :: 4.7 tonsAccording to Endaya, since clean-up efforts began in October 2022, more than 4.7 U.S. tons of garbage have been collected and exchanged for nearly 3 tons of rice.
