Scientists In National Aeronautics and Space Administration (NASA) a National Oceanic and Atmospheric Administration (NOAA) I decided on a new study Earth’s atmosphere The “unprecedented” heat wave caused the planet’s energy imbalance to double between 2005 and 2019.
NASA described the blue marble in a statement released Tuesday Weather It is determined by the balance between the amounts The sun Energy is absorbed into the atmosphere and surface, as well as the amount of infrared radiation. Room.
According to a recent study published in 2005 Geophysical Survey Letters, the sum of these two components of energy determines whether the earth is warming or cooling.
“The concentration of well-mixed greenhouse gases in the atmosphere increases exponentially and the time it takes. The ocean, The cryosphere and the Earth increase with this increase in energy to achieve thermal equilibrium and thus the Earth warms up, ”says the study summary. This extra energy (about 90%) heats the oceans, while the rest heats the earth, melting ice and snow and warming the atmosphere. “
To reach these conclusions, the agency’s researchers compared data from NASA’s clouds and the Earth’s Radiation Energy System (CERES). Satellite sensors In the universal measurement range from “Argo” in the ocean.
“We show that these two independent approaches will lead to an increase in the Earth’s energy energy rate from mid-2005 to mid-2019, with clouds, sea ice and mixed greenhouse growth reducing energy reflection into space. Gas and steam.”
Increases in greenhouse gases such as carbon dioxide and methane cause global warming, trapping warming radiation, melting snow and ice, and other changes.
“The result of all these factors is the Earth’s energy imbalance.” Says in a NASA statementThe authors of the study examined the findings of cloud, water vapor, micronutrient gas, sunlight, surface albedo, aerosol light emission, and surface and atmospheric temperature distributions.
In addition, the researchers found changes Pacific Decade (PDO), The Pacific Climate Change to the Energy Phase “Energy may have played a major role in increasing energy imbalances”.
A similar warm-up phase of the PDO from 2014 to 2020 led to a decrease in cloud cover and increased solar absorption.
“The two independent ways of looking at changes in the Earth’s energy imbalance are interrelated, and both show this great tendency, and we’re very confident that this is a real phenomenon for Webb,” said Ceres, lead researcher at NASA’s Layley Research Center. “The trends found are a little intimidating.”
“It’s probably a combination of human influence and inherent diversity,” he added. During this time, both of these causes the temperature to rise, causing a major change in the Earth’s energy balance. The rate of growth is unprecedented.
Finally, the study found that the Earth will experience more climate change if the rate of heat absorption does not decrease.
