Climate change: what we need to know and change to save our planet
Climate change: a definition
Climate change has already happened over the 4.5 billion years of history. Remember Ice Age? This is usually what climate-skeptics will say when you talk about climate change. This is true, except these natural cycles of warming and cooling have nothing to do with the massive shifts in temperature that our environment is experiencing. Climate change has found a new definition now because of timing: a shift that would normally take hundreds of thousands of years to occur, now happens in decades. Since 2001, 17 of the 18 hottest years ever recorded have taken place. The problem is that when it comes to climate change facts don’t seem to have the same impact as profits and it may be too late when the population, the government and the big corporations decide to act jointly and effectively.
Climate change: causes and effects
Once upon a time there was an Industrial revolution that “increased” the wealth and the well-being of the world population: technologies and factories seemed to have the right answer for a bright future. The only problem was its secret ingredient: carbon dioxide.Human activity in fact requires coal, oil and gas to produce energy for homes and transports which in turn produces carbon dioxide, the number one culprit for this faster warming. So if you want to know the cause, grab a mirror and take a good look: it’s us.
The effects of climate change are numerous and interconnected: temperature rises (increasing the gap between minimum and maximum), the sea levels rise, the ocean increases in temperature, heavy precipitations are more frequent and the glaciers, including the permafrost are thawing. Last year, the world’s leading climate scientists warned we only have 12 years to limit global warming to a maximum of 1.5C and avoid climate breakdown.
