Global Warming and its Effects on Ice Ages
The effects of global warming could end up making the planet colder over time. This might seem counterintuitive, with global warming in the spotlight, but researchers are finding that climate change is not only capable of causing an ice age, but could in fact be the cause.
The reason behind this is that global warming could drastically reduce the amount of snow and ice that accumulates in the Arctic and Antarctic regions. When this happens, less radiation from the sun is reflected back into space and more stays trapped on earth. This heat can cause sea ice to melt and destabilize the polar vortex — a ring of strong winds that protect us from colder temperatures. The weakened Arctic winds allow the cold air to escape towards the equator, where it can cause harsher winters in the northern hemisphere.
While most research on global warming and its climate effects has focused on the northern hemisphere, a recent study from the University of Toronto found that the southern hemisphere is also vulnerable — and not to just reduced snow and ice. Leading researcher Dorian Abbot said that in addition to melting ice, global warming can also be responsible for changing weather patterns that can trigger a cooling spell in the region. These conditions could result in a decrease in temperatures over several years and ultimately lead to an ice age.
Rising oceans levels are likely to accelerate any ice age, as melting glaciers and ice sheets will cause the oceans to become warmer. This will also result in stronger storms, more extreme weather and increased flooding. Additionally, these rising waters will reduce the amount of land exposed to sunlight, resulting in further cooling.
Experts are warning that these effects are likely to be noticeable in our lifetime and yet, it’s not too late. By curbing our reliance on fossil fuels, reducing emissions and improving energy efficiency, we can still make a change for the better. Sustainable energy, renewable resources and green technology are already making a difference, and small changes like switching off lights are also having a positive impact.
Ultimately, global warming could lead to an ice age, but it doesn’t have to. With our collective efforts, we can still preserve the planet and limit the effects of climate change. Now is the time for meaningful action — for individuals, businesses and governments — so that our children may live to see a planet that hasn’t been ravaged by the effects of global warming.
