The earth is getting warmer by the second, With record warm temperatures coming up every year. In fact, according to NASA, the rate of temperature increase has nearly doubled in the last 50 years. So it’s safe to say that global warming does exist and is continuing to be a big problem. To be completely sure, we need to look at a bunch of other factors that account for climate change.

The melting of glaciers can lead to harsh conditions like landslides, avalanches, and loss of pure water for the people who rely on the consumption of melted glacier water. Also, Melted Glaciers can be replaced by snowfall in the winter, but this leads to an overall decrease in glacial mass.

According to EPA, The overall glacier mass in the US has been decreasing every year since the 1970s. It is also predicted that by 2100, china would experience a 75% decrease in overall glacial area. Melted Glaciers can be replaced by snowfall in the winter, but this leads to an overall decrease in glacial mass.

The arctic sea ice cap increases during winter and diminishes in the summer reaching its lowest point in September.

The area became smaller every year, for the past 30 years, decreasing by 3.2% per decade.

As glaciers melt and water temperatures increase, the oceans start to expand leading to an overflow of water; this is called the thermal expansion of water.

Research has shown that the sea level has been rising at a rate of 0.04 to 0.1 inches per year.

Such a condition would affect the people that live in coastal areas by exposing them to floods and storms. And also, marine life is threatened as there could be an intermixing of fresh and saltwater.

As the air near the ocean gets warmer, evaporation starts to take place, leading to an increased amount of water vapor in the air; the water vapor contributes to excess warming and in some cases, extreme precipitation events like hurricanes and floods.

Humidity is the presence of water vapor in the air which gets evaporated when the surface temperature warms. And since water vapor is a greenhouse gas, the increase in humidity can directly cause additional warming.

Another factor to look at is, many people use air conditioners during humid conditions leading to more energy loss, causing climate change.

As temperatures rise, the snow melts early, which could endanger the lives of those who rely on consuming melted snow water.

According to NOAA, Areas covered by snow in the northern hemisphere are found to reduce in size.

Snow can naturally reflect the sun’s energy into space which can help in keeping the planet cool. But as the snow melts, it is replaced by dark land and oceans which absorb energy, causing the opposite effect.
