Climate Change and the Last Ice Age by City-Tech Blogger Jerry Camilien

My hypothesis is that climate change and global warming may have played a role in the last ice age. The question is how would an ice age that lasted for millions of years thaw out without the effects of global warming? So, climate change is nothing new if you look at ancient history where abnormal changes in the climate were occurring across the planet. The ice age affected most of the northern hemisphere approximately 2.6 million years ago according to scientists, but it’s even older than that. Climate scientists are still working to understand what caused the ice age, but they claim it is the amount of sunlight that enters Earth. When more sunlight reaches the northern hemisphere, the temperatures rise then ice sheets melt, and the ice age start to decline around 10000 years ago. The ice sheets melting caused sea levels to rise causing massive flooding across the planet. Leading to the end of prehistoric species like dinosaurs who may have drowned in the great floods. Displacing prehistoric civilizations who hunted for food and maintained shelter. The shifting of land masses causing spreading and gaps at a time when land masses which were attached millions of years ago the term which is called Pangaea. The spreading apart process occurred for millions and millions of years that gives us the geographic landmass we have today on our global maps. Today, we are seeing history repeating itself with Arctic ice caps melting sheeting of ice but this time around it seems more so due to human activities that are affecting the climate. Arctic sea ice has been shrinking steadily in recent decades, damaging the livelihoods of indigenous peoples and wildlife such as polar bears. Leading to increase sea levels that continue to grow more and more affecting the intensity of floods, tropical storms, and hurricanes. On the other hand, this has opened the region to more shipping and oil and gas exploration. One way to mitigate climate change is returning to the Paris Agreement that the current U.S. President withdrawn from. With the help of over 100 different nations we can limit climate change effects. We do need all the help we can get, we can do it alone, but this a global concern.
