Climate change, If the warming were caused by a more active Sun, then…
Climate change
Evidence
Global temperature rise
The planet's average surface temperature has risen about 2.05 degrees Fahrenheit (1.14 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.
Warming ocean
The ocean has absorbed much of this increased heat, with the top 100 meters (about 328 feet) of ocean showing warming of more than 0.6 degrees Fahrenheit (0.33 degrees Celsius) since 1969.
Shrinking Ice sheets
Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 279 billion tons of ice per year between 1993 and 2019, while Antarctica lost about 148 billion tons of ice per year.7

Ocean acidification
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30%.13,14 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the ocean.
Solution
-
Adaptation
adaptation is a change in how we live in our past climate to match the present or future. in the past years.
we and other living things must reduce the impacts of climate change because this doesn't fact some people but the whole world in a negative way. We just have to maintain the beneficial ones, like a longer growing season. i
the population have already had some changes to adapt to, but the climate is changing very fast so this results in a harder way to make new changes, : the harder it'll be to make new changes
-
Causes
There are four different gases that cntribute to climate change such as: water vapor, nitrous oxide, methane and carbon dioxide
-
Carbon dioxide is released by: Respiration, burning fossil fuels, deforestation and others
-
methane is produced by: decomposition of wastes in landfills, agriculture, rice cultivation, ruminant digestion and manure management associated with domestic livestock.
Nitrous oxide is produced by soil cultivation practices, by commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
-
If the warming were caused by a more active Sun, then scientists would expect to see warmer temperatures in all layers of the atmosphere. Instead, they have observed a cooling in the upper atmosphere, and a warming at the surface and in the lower parts of the atmosphere. That's because greenhouse gases are trapping heat in the lower atmosphere.
