Объяснение:

Greenhouse Gases: The primary contributors to global warming are greenhouse gases, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases trap heat in the Earth's atmosphere, leading to a warming effect known as the greenhouse effect.

Human Activities: Industrial processes, deforestation, burning of fossil fuels (coal, oil, and natural gas), and certain agricultural practices release substantial amounts of greenhouse gases into the atmosphere. The increased concentrations of these gases enhance the natural greenhouse effect, causing the Earth's surface temperature to rise.

Temperature Rise: Over the past century, the Earth's average surface temperature has increased, with notable warming trends in recent decades. This warming is associated with various climate-related changes, including more frequent and severe heatwaves, changing precipitation patterns, and rising sea levels.

Effects on Climate: Global warming contributes to climate change, leading to alterations in weather patterns and increased frequency of extreme weather events such as hurricanes, droughts, floods, and wildfires. These changes have widespread impacts on ecosystems, agriculture, water resources, and human communities.

Melting Ice and Rising Sea Levels: The warming climate accelerates the melting of glaciers and ice caps in polar regions and contributes to the shrinking of sea ice in the Arctic. Melting ice contributes to rising sea levels, posing threats to coastal communities and ecosystems.

Ocean Acidification: Increased absorption of carbon dioxide by the world's oceans leads to ocean acidification. This has harmful effects on marine life, particularly organisms with calcium carbonate shells, such as corals and certain shellfish.

International Efforts: The international community recognizes the importance of addressing global warming. Agreements like the Paris Agreement aim to limit the global temperature increase to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit it to 1.5 degrees Celsius.

Renewable Energy and Mitigation: Transitioning to renewable energy sources, improving energy efficiency, afforestation, and adopting sustainable practices are crucial for mitigating global warming. These efforts aim to reduce greenhouse gas emissions and promote a more sustainable and resilient future.

It's important to stay informed about ongoing research, policies, and initiatives aimed at addressing global warming and its associated impacts on the environment and society.

Answer 2

Ответ:

Over the past 140 years, the average annual temperature has increased by about 1°C.

It is important to understand that during its existence the Earth's climate has changed quite often. This is due, first of all, to changes in the orbit of our planet: the orbit either “stretches out” or becomes more rounded (the cycle is approximately 93 thousand years). In addition, the angle of inclination of the earth’s axis to the orbital plane changes every 41 thousand years, and the cone of rotation changes every 26 thousand years. The combination of these factors directly affects the amount of solar heat that enters high latitudes (the Arctic and Antarctic), and therefore the formation of glaciers.

So why is there so much talk about climate change, since current fluctuations can be explained by cyclicality?! The fact is that the air temperature on Earth has not increased so quickly for at least the last 800 thousand years. This was discovered by a group of European scientists who studied the ice of Antarctica (details here). And the overwhelming majority of experts believe that the rate of climate change can only be explained by the anthropogenic factor, i.e. human activity.
