Another alarming change that scientists have witnessed is an extreme rise in ocean temperatures. In fact, they have recorded a 0.75 degree Celsius warming per decade. This increase in temperature is detrimental to the organisms the call the ocean home. In fact, warming seas fueled by climate change has exacerbated Sea Star Wasting Syndrome, which causes sea stars to dissolve. It's gotten so bad that their populations are just a fraction of what they used to be.
Another concerning consequence of climate change is ocean acidification. The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning fossil fuels and changing land use the amount of carbon dioxide absorbed by the ocean also increases. This process has an especially devastating effect on shell organisms. Ocean acidification prevents calcium carbonate from being used to create shells and takes the calcium carbonate from the organisms that are alive.
While this tour was deeply enlightening, it reinforced just how pressing the threat of climate change truly is. It is incumbent upon members of Congress to advance legislation that will reduce our reliance on fossil fuels, provide our parks the resources necessary to adapt to these changes and ultimately avoid further damage to our planet. If we don’t act, generations of Americans after us will be left wondering why we failed them and why we failed to protect our national treasures from climate change.
