Bill Nye and Leonardo DiCaprio have finally begun to open people’s eyes to the dangers of global warming with their hit documentaries, but is it too late? Scientists have recently revealed that flooding has already been occurring in coastal cities in not only the U.S. but around the world. Flooding has managed to leak its way into houses and sea levels are still on the brink of rising even higher due to melting glaciers.
Here’s what’s happening and why
Recently, a team of scientists published a study that found that the rate of sea level rise in the 20th century was greater than it had been in 2,800 years according to the Climate Institute.
Sea levels have risen almost 3 inches globally in the most recent 20 years and rise on an average of 1/8 inch each year. Melting land ice is responsible for a larger—and ever-increasing—amount of the global sea level rise in recent decades, as opposed to thermal expansion of seawater.
The Climate institute also claims that a compounding problem with ice melt is that it can accelerate through positive feedback. Snow-covered ice has a high reflectivity or albedo, which means that radiation is reflected back from it and not as much is absorbed as heat. Water, however, has a very low albedo and does absorb high amounts of solar radiation and heat held in the earth’s lower atmosphere.
Louisiana floods have been directly linked to climate change
According to news outlet, Climate Central, claims that the storm that recently hit Louisiana is directly caused by the emissions that we are putting into our atmosphere.
“Climate change played a heavy role in the storm that brought a three-day deluge to coastal Louisiana last month, triggering floods that killed 13 and left thousands more homeless, research showed,” claims Climate Central. “The unprecedented 1 to 2 feet of rain that fell over parts of Baton Rouge and nearby communities over several days in the middle of August stunned experts. While such deluges are rare, the new research indicated that the likelihood the region will experience them may have doubled during the past century.”
The future dangers
PBS has already made a map of the cities that are likely to be underwater by 2045. Among these cities are New Orleans and Miami. The reality is that scientists have actually identified over 144 cities just in the U.S. that likely to take the plunge. This means tons of chaos for not only society but economy as a whole.
You are mistaken if you don’t think that your tax dollars will be spent on all the damage that is done in the aftermath of the world wide flooding. Not to mention the amount of citizens that will be now homeless and looking for homes in your area.
What we can do
Unfortunately, climate change is irreversible, but it can be slowed down. All we have to do is slow down our use of dangerous emissions into the atmosphere. You can do this by changing your diet, recycling and reducing your use of pollution.
