There has been a great deal of incontrovertible evidence of climate change that simply can't be ignored any longer. The world has been gradually changing for the past years and most of these changes, unfortunately, are not even good changes at all. On the contrary, the effects of climate change will be devastating to the human race along with every other species on the planet.

Incontrovertible Evidence

Without doubt, there are several phenomena happening around the world right now that serve as physical evidence of climate change.

Needless to say, there is a lot of theory behind climate change, namely sophisticated climate models which describe:  the greenhouse effect, the roles of various greenhouse gases (along with their GWP) and climate feedbacks.

Without further ado, here is a list of some of these changes that scientists are observing as we speak which act as evidence:

Rising Temperatures

The ten hottest years ever recorded all took place since 1998, with the hottest one of all being 2014. Clearly, the rising of the global temperature is strong evidence of climate change. Since the 1880s, it has been noted that the Earth is continuously warming up, most of which took place in the 1970s. During the 2000s, decline of the solar output happened, which resulted to a unique deep solar from 2007-2009. Up to now, the Earth’s temperature is still rising.

The increasing temperature of the oceans is also an evidence of climate change. Experts noted that the oceans are absorbing the sun’s heat in an increasing rate. Warming has increased since the year 1969 wherein the oceans showed warming at 0.302 degrees Fahrenheit. Incidentally, the increase in carbon dioxide in oceans has also led to ocean acidification.

Rising Sea Levels

A good evidence of climate change is the rising sea levels. During the last century, sea levels rose by about 6.7 inches and now, the rate continues to accelerate.

Melting of Glaciers and Polar Ice Caps

The withdrawal of the glacial formations in several parts of the Earth, particularly those in the Himalayas, Africa, Alps, Andes, Alaska, and Rockies as a reaction to the twentieth century global warming is yet another evidence of climate change. Since 1966, the reduction of the snow cover has already reached the extent of about 10%.

Similarly, the melting of polar ice caps poses as another piece of evidence. For the past decades, the Arctic ice has been lessening in a rapid rate, with the range and density continuing to decline. Moreover, some scientists say the Arctic will become ice free by as early as 2020. Its area reached its lowest in 2012

Other Drastic Changes

Since the 1950s, high temperatures have been attributed as the cause behind the increasing instances of severe rainfall experiences in the United States.

Overall, extreme weather events which include tropical stormshurricanesheat wavesdroughtswildfires, and floods have been increasing in frequency and intensity around the world.

Mass desertification is drying up large areas of arable land in various parts around the world. For instance, the Sahara Desert is enlarging by a rate of 48 kilometers per year. Reports say that over 1 billion people are under threat from further desertification.

Diseases such as malaria and dengue fever are not only targeting more people, but are expanding to new areas as a result of higher temperatures.
