Is global warming real?
Many people seem to believe that global warming is real whilst others seem to think it’s just another silly rumor flying around and that it’s not real like Y2K. But if global warming wasn’t real how could one possibly explain all the things that are happening to the earth? Global warming is in fact real and now the effects are more prominent than ever. The polar ice caps are melting, sea levels are rising, and the weather has been all over the place. Scientists are telling us that this is what global warming looks like and that we have to do something to fix it soon and fast or else we may not have a sustainable planet to live on anymore.
The effects of global warming are the social and environmental changes caused either directly or indirectly by the emissions caused by greenhouse gases. Although many people dismiss the thought of global warming claiming that is “doesn’t exists” there is a scientific consensus that climate change is occurring, and that human activities is the primary causes. There have been many climate changes that have already been observed, such as glacier retreat, changes in the timing of seasonal events such as the flowering of plants and even changes in agricultural productivity.
One of the most dramatic effects of global warming is the reduction in Arctic sea ice. In 2012, scientists observed the smallest amount of Arctic ice ever recorded. Most analyses project that, within a matter of years, the Arctic Sea will be completely ice-free during the summer months. This is completely mind-blowing because the Arctic Sea used to be riddled with ice caps and ice everywhere and now within a matter of a few more years it’ll be a summer paradise free of ice during the summers which in this case is not a good thing. Going off that it’s safe to assume that in a decade or so the Arctic Sea will have little to no ice season round which is devastating to say the least.
Another effect of global warming that was previously stated is glacial retreat. Only 25 glaciers bigger than 25 acres are now found in Montana's Glacier National Park, where there was once about 150 glaciers found, according to the U.S. Geological Survey. A similar trend is seen in glacial areas worldwide due to global warming.
Not only is the glaciers affected but the effects of global warming on the Earth's ecosystems are expected to be widespread and devastating. There has already been a mass migration of plants and animals that are now moving their range towards north or to higher altitudes because of the rising temperature, according to a report from the National Academy of Sciences. Warmer temperatures will also expand the range of many disease-causing pathogens that were once confined to tropical and subtropical areas, killing off plant and animal species that formerly were protected from disease.
These coupled with the other effects of global warming, if left unchecked, will likely contribute to the disappearance of up to one-half of Earth's plants and one-third of animals from their current range by 2080, according to a 2013 report in the journal Nature Climate Change.
Future effects of climate change will vary heavily on two factors which is the climate change policies and social development. The two main policies that currently address climate change are adapting to the impacts of climate change and reducing human greenhouse gas emissions. We first have to be able to reduce the amount of greenhouse gases we produce and then figure out a way to adapt to the earth we have created. Another possible option is Geoengineering which is the artificial modification of the Earth’s climate systems through two primary methods, Solar Radiation Management (SRM) and Carbon Dioxide Removal (CDR).
However, with all this being said there still are solutions out there. For starters, we have to cut carbon pollution by reducing our dependency on fossil fuels by using a cleaner, more renewable energy such as solar power. We would also have to implement new policies that help prepare us for the consequences of climate change such as storms, flooding, drought, and etc. But first and foremost, we need a national leadership that will address what the earth and scientists are telling us about global warming instead of ignoring it because at this point in time that is the only way to save the earth.
