Step-by-step explanation:
Global Temperature Rise: Average global temperatures have been rising over the past century, with the last few decades experiencing accelerated warming. This is primarily due to increased concentrations of greenhouse gases in the atmosphere.
Melting Glaciers and Ice Sheets: Many glaciers and ice sheets around the world, including those in the Arctic and Antarctic, have been shrinking due to warmer temperatures. This contributes to rising sea levels.
Sea Level Rise: As glaciers and ice sheets melt, and as warmer water expands, global sea levels are rising. This leads to coastal erosion, increased flooding, and threats to low-lying communities.
Ocean Acidification: The oceans are absorbing a significant amount of the excess carbon dioxide from the atmosphere. This leads to increased acidity in the oceans, which can harm marine life, particularly coral reefs and shellfish.
Extreme Weather Events: There is evidence of an increase in the frequency and intensity of extreme weather events such as hurricanes, droughts, heatwaves, and heavy rainfall. These events can have devastating impacts on communities and ecosystems.
Shifts in Ecosystems: Changes in temperature and weather patterns are affecting ecosystems and the timing of natural events such as animal migrations and plant blooming. Some species are struggling to adapt, leading to imbalances in ecosystems.
Changing Rainfall Patterns: Climate change can alter precipitation patterns, leading to shifts in rainfall distribution. Some areas experience increased rainfall and flooding, while others face drought and water scarcity.
Threats to Biodiversity: The changing climate can disrupt habitats and threaten the survival of many species. Some animals and plants might struggle to find suitable conditions to survive.
Ocean Warming: The oceans have absorbed much of the heat from global warming. Warmer ocean temperatures can impact marine life, including coral reefs and fisheries.
Rising CO2 Levels: The concentration of carbon dioxide in the atmosphere has risen significantly since the industrial revolution due to activities like burning fossil fuels and deforestation. This is a major driver of global warming.
