The Earth’s climate has been changing since the beginning of time, and it will continue to do so in the future. In recent decades, scientists have observed an increase in global temperatures due to human activities such as burning fossil fuels, deforestation, and agricultural practices. These changes are causing sea levels to rise, extreme weather events to become more frequent and intense, and glaciers and ice sheets to melt at a faster rate. Scientists believe that these trends could have serious implications for our planet’s ecosystems, economies, and societies.
