Is Global Warming Real? The Evidence

Is Global Warming Real? The Evidence

‘Scientific evidence for warming of the climate system is unequivocal’.

– Intergovernmental Panel on Climate Change

Global warming is one of the most discussed subjects in the world, cropping up in politics, news reports and schools. Although there is certainly proof that the earth is warming, the debate about whether global warming is real continues. The climate is certainly a complex system. However, with constant advancements in technology, we are now able to understand global warming more than ever before. Earth-orbiting satellites allow scientists to see the bigger picture, collecting as many different types of information about our planet. This body of data is collected over many years and reveals to us the rate of our changing climate. During the last four decades, the rate at which scientists have added to the body of knowledge of atmospheric and oceanic processes has accelerated dramatically.

There are plenty of organisations that are publishing evidence backed by scientists that prove global warming is  happening. Read more about at National Geographic and NASA for evidence that proves global warming is happening and it is happening now.

How is Climate Change Measured?

There is no single instrument measuring climate change. Instead, there are thousands of measuring devices spread across the globe, on land, under the sea and in the air. Evidence of global warming can be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.

The current global warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years. There is no question that increasing levels of greenhouse gases are causing the earth to warm. But lets look at the evidence.

Trees

 

 

 

 

 

 

 

The study of the growth of tree rings is known as dendrochronology and is the relationship between climate and tree growth. Trees contain some of nature’s most accurate evidence of the past, recording evidence of floods, lightning strikes, droughts, insect attacks, and even earthquakes that occurred during the trees lifespan. Each tree will store information about the climate in which it lives through the formation of rings. Every year, trees form new rings as they grow. The subtle changes in the thickness of rings, a result of varying weather conditions, can indicate changes in the climate during the trees lifespan. Scientists have been studying tree rings for decades to understand how our climate is evolving and changing.

Lakes and Oceans

 

 

 

 

 

 

 

 

Another telling sign of climate change is buried deep in our lakes and oceans. When evaluating the sea bed, scientists can uncover sediment layers going back millions of years. These layers of sediments contain a wealth of information about what was in the air and water when they fell, indicating the changes to climate.

A combination of satellite data and ground measurements have been used by scientists to provide a comprehensive view of changing lake temperatures worldwide.  When our water temperatures are fluctuating, it influences the health of multiple ecosystems and many life forms in our lakes and oceans are rapidly disappearing because their habitats are being effected so negatively by climate change.

Polar Ice Sheets

 

 

 

 

 

 

 

 

Scientists have been drilling cores through the Earth’s polar sheets for decades to learn more about climate progression. Tiny bubbles of gas that have become trapped in the ice are pieces of the Earth’s atmosphere that have literally been frozen in time. It is through examining these gases that scientists can uncover the concentrations of greenhouse gases and learn more about how our climate is changing. Furthermore, it was through this very method of drilling into the polar ice sheets that scientists discovered that the concentrations of greenhouse gases (since the industrial revolution) are higher than they have ever been for hundreds of thousands of years.

Rising Global Temperature

The global temperature is on the rise and has been steadily rising for the past century and a half. Scientists have evidence on all three of the major global surface temperature reconstructions that show Earth has been warming since 1880. In fact, the most significant warming has occurred in the past 35 years. In 2001 we had some of the warmest years on record. Check out the evidence in the National Centers For Environmental Information. 

Rising Sea Levels 

 

 

 

 

 

 

 

When sea level rise they can cause destruction of natural habitats, soil contamination, lost habitats for animals, wetland flooding and much more. As the problem of global warming gets worse, hundreds of millions of people live in areas that will become increasingly vulnerable to flooding. Rising sea levels would force them to abandon their homes and relocate. Many low-lying islands are being submerged completely. Check out the evidence for rising sea levels on the NASA Website confirming the rising sea levels.

Glacial Retreat

Glaciers are retreating almost everywhere around the world – including the Alps, Andes, Himalayas, Rockies, Alaska and Africa. Large ice formations, like glaciers and polar ice caps, naturally melt and retreat during the summer months. And then in the winter, it snows and the ecosystem balances itself out again. However, recently persistently high temperatures that are caused by global warming have resulted in increased summer melting and decreased snowfall in the winters. Due to this imbalance, sea levels are rising.

Extreme Events

 

 

 

 

 

 

 

 

 

As the majority of people know, climate change can cause extreme weather events. Natural disasters are often depicted in films such as ‘The Day After Tomorrow’, warning us of the dangers of climate change. Sadly, films like this are on the rise as so many people are trying to raise awareness of the increasing threat of global warming.

Global warming is rapidly making our days warmer, causing severe floods and devastating droughts. Basically, the world’s climate is all over the place. Such a changeable and unpredictable climate is a great risk to animal and human habitats alike. This intensification of climate extremes is one of the most visible impacts of global warming in our everyday lives.

Conclusion

In recent years, global warming has caused a great deal of political controversy. As scientific knowledge and understanding has grown, the debate is moving away from whether humans are causing global warming and toward how best to respond. Here at James Waste we are passionate about caring for the environment and passing on our planet to the next generation healthier than we found it. Understanding global warming and its impact is important because it will equip up with the knowledge to face the problems posed by it.

Most predictions say the warming of the planet will continue and is likely to accelerate. Global warming is real, climate change is happening right before our eyes and we need to fight to protect this beautiful planet of ours.
