Recent research based on sea levels shows how the current climate is affected, and it might change its trajectory in the future. Such a fact was highly influenced because of Earth’s last warm period 125,000 years ago, the sea levels increasing up to 10 meters above present levels. The study explains how Antarctica had a negative role, because of its ice sheets can switch quickly, and in such ways that could have immense implications for coastal populations and infrastructure in the future.
Our planet is known to have both cold glacial moments, and warmer interglacial ones when the ice melts and sea levels increase. We find ourselves right now in an interglacial period, which started almost 10,000 years ago. The greenhouse gas emissions from the last 200 years have such a negative impact that climate changes are more active and more intense than during the previous interglacial period. What does this fact mean exactly? According to the study, the last rates of the increasing sea level bring just low-end forecasts of what might result in the future. The analyzed information and data from the previous interglacial shows that the temperatures were up to 1 Celsius higher than today.
Moreover, the study indicates that ice melt in the previous interglacial moment created global seas to increase almost up to 10 meters above the current level. Also, the carbon dioxide levels were only 280 units per million, compared with more than 410 today.
What Could We Expect
Nowadays, greenhouse-gas-driven climate change, ice loss, and warming are occurring in both poles at the same time. Such a fact indicates that if climate change advances unabated, our planet’s previous extreme sea-level rise could be a slight suggestion of what should we expect.
