Question

what is the primary cause of increased worldwide temperatures? solar flares natural climate cycles human activity releasing greenhouse gases volcanic eruptions

Explanation:

Human activities, such as burning fossil fuels (coal, oil, and gas), deforestation, and industrial processes, release large amounts of greenhouse gases (like carbon dioxide, methane) into the atmosphere. These gases trap heat from the sun, leading to the greenhouse effect and increased global temperatures. Solar flares have a negligible long - term impact on global temperatures. Natural climate cycles exist but cannot account for the rapid and significant temperature increase observed in recent decades. Volcanic eruptions can have a short - term cooling effect due to the release of aerosols that block sunlight, but this is temporary.

Answer:

Human activity releasing greenhouse gases
