The Vostok ice core graph shows a pattern of warming and cooling over the past 420,000 years. Since 1880, the Earth's climate has been warming due to human activities, such as burning fossil fuels and deforestation. This has caused the global average temperature to increase by 1.1°C since 1880. This warming trend is expected to continue, resulting in a shift in the pattern of warming and cooling shown on the Vostok ice core graph. The graph will show a more rapid and sustained warming trend, with fewer cooling periods. This could lead to more extreme weather events, such as heat waves, droughts, and floods.
