Although we can see that the Earth is getting warmer as a result of exposure changing of the climate continue to intensify, clouds on our planet are making our planet hotter than ever, scientists fear.
Using a new approach to analyzing satellite data, scientists in a new study suggest that Earth’s clouds could make matters worse. global warming with time. This work, carried out by researchers at Imperial College London and the University of East Anglia in the UK, provides evidence of a high likelihood – roughly 97.5% – that clouds will intensify global warming.
“Over the past few years, there has been growing evidence that clouds are likely to have an exacerbating effect on global warming,” study co-author Per Novak, a researcher at the University of East Anglia and Imperial’s Grantham Institute and Data Science Institute. said in a statement… “However, our new approach allowed us for the first time to obtain the global significance of this feedback effect, using only the highest quality satellite data as the preferred line of evidence.”

Many countries have signed the Paris Agreement, an international treaty that pledges to limit global heating to 2 degrees Celsius (3.6 degrees Fahrenheit), or ideally 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels.
However, according to this study, global warming is unlikely to remain 2 degrees Celsius (3.6 degrees Fahrenheit) lower than pre-industrial levels and is likely to rise by more than 3 degrees Celsius (5.4 degrees F). , according to the same statement. …
The researchers point out that one of the main uncertainties in predicting the future climate is clouds and how they might change in the future and affect the temperature rise. Depending on how dense they are and where they are in the atmosphere, clouds can make warming less severe or much more severe.
In this study, the researchers developed a new method, inspired by machine learning, that took satellite data about clouds, their temperature, humidity, and wind conditions into account to study clouds and how they will affect the climate in the future. Scientists have found that in the future, cloud cover will actually make climate change and temperature rise much more extreme, both by less reflection of solar radiation from the Earth and by increasing solar radiation. Greenhouse effect…
“The value of climate sensitivity is highly uncertain, and this leads to uncertainty in future projections of global warming and in the remaining ‘carbon budget’ – how much we can emit before we reach the overall target of 1.5 degrees Celsius or 2 degrees Celsius globally. “warming,” co-author Paulo Ceppi, a researcher at the Grantham Institute, said in the same statement.
“There is therefore an urgent need to better quantify how clouds will affect future global warming. Our results will mean that we are more confident in climate predictions and can gain a clearer picture of the severity of future climate change. This should help us know our limits – and we take steps to stay within them, ”added Chappy.
