Accurate computer climate models essential in understanding future implications of human-driven climate change.
Earth's climate system model, E3SM, overestimates albedo by about 5% due to underestimation of microphysical properties impact on ice reflectivity.
New finding will help improve climate models' accuracy and provide a clearer understanding of Earth's climate system.
Scientists from UC Irvine and University of Michigan discover overestimation of ice reflectivity in older climate models due to lack of consideration of microphysical properties like algae and dust.
In recent developments, Earth system scientists from the University of California, Irvine (UC Irvine) and the University of Michigan have discovered a significant missing piece in climate models. The team led by Chloe Clarke from UC Irvine and Charles Zender from UC Irvine and University of Michigan found that older model versions overestimated ice reflectivity due to lack of consideration of microphysical properties like algae and dust, leading to an increase in Greenland Ice Sheet melting by about six gigatons more than in older model versions. This discovery is crucial as accurate computer climate models will be essential in understanding the future implications of human-driven climate change.
The study, published in the Journal of Geophysical Research: Atmospheres, reveals that Earth's climate system model, E3SM, overestimates a key physical property called albedo. Albedo is the degree to which ice reflects planet-warming sunlight into space. The team found that old model versions underestimated the impact of microphysical properties like algae and dust on ice reflectivity by about 5%. This new finding will help improve climate models' accuracy and provide a clearer understanding of Earth's climate system.
Meanwhile, extreme weather events continue to pose challenges around the world. In Nepal, a landslide swept away two passenger buses from the highway into a nearby river. Sherpas in the Himalayas are battling climate change and its impact on their livelihoods, culture, and environment. More than 161 million people are under heat alerts as extreme weather conditions prompt warnings and health fears. The severity of these events highlights the urgent need for accurate climate models to help mitigate their impacts.
Additionally, new research shows that human-caused climate change is affecting Earth's rotation and increasing the length of each day. This trend, set to accelerate over this century as humans continue to pump out planet-heating pollution, has important implications for our high-tech world. GPS systems and other computing systems rely on precise time measurements, making these changes significant.
Earth system scientists have discovered a missing piece in climate models.
The new ice reflectivity incorporated into the model has increased the Greenland Ice Sheet’s melting rate by about six gigatons more than in older model versions.
Chloe Clarke, a project scientist in UC Irvine professor Charlie Zender’s group, led the study published in the Journal of Geophysical Research: Atmospheres.
New research shows that human-caused climate change is affecting Earth’s rotation and increasing the length of each day.
Climate change is now a bigger influence on time than previously thought, outpacing the moon’s role in increasing day length.

Polar ice melt caused by global warming is changing the speed of Earth's rotation, with a trend set to accelerate over this century.
Deception
(80%)
The article makes several statements that are not deceptive but do contain some elements of sensationalism and selective reporting. The author states that 'climate change is messing with time more than previously thought' and 'climate change could become the new dominant factor.' These statements are sensational in nature as they imply a greater impact of climate change on time than what has been previously known or suggested. However, the article also provides evidence to support these claims through scientific research and data. The author also selectively reports on certain aspects of the study, focusing on the impact of climate change on day length without mentioning other factors that influence Earth's rotation such as processes in its fluid core and moon's pull. This could give readers a skewed perspective of the situation.
If the world is unable to rein in emissions, climate change could increase the length of a day by 2.62 milliseconds by the end of the century – overtaking the natural impacts of the moon.
The impacts of human-caused climate change are so overwhelming they’re actually messing with time, according to new research.

Bias
(95%)
The author expresses a clear bias towards the idea that human-caused climate change is having a significant impact on the Earth's rotation and day length. She uses language such as 'overwhelming', 'huge impact', and 'gravity of ongoing climate change' to depict climate change in an extreme manner. The author also quotes scientists who express similar views, further reinforcing this bias.

It’s yet another sign of the huge impact humans are having on the planet.

The article contains an appeal to authority when it states 'a team led by researchers from the UC Irvine Department of Earth System Science and the University of Michigan Department of Climate and Space Sciences and Engineering reveal how a climate model commonly used by geoscientists currently overestimates a key physical property of Earth’s climate system called albedo.' This statement implies that because these researchers have made this discovery, it is true. However, while their expertise lends credibility to the findings, it does not automatically make the statement free from fallacies.
