Chichén Itzá is located in Tinum, Yucatan, Mexico. With the most common natural disasters in New Mexico consisting of wildfires, floods, severe storms, extreme heat and drought, landslides, winter storms, tornadoes, and power outages, Chichén Itzá faces many threats due to climate change. The Chichén Itzá is mainly built with limestone which is highly susceptible to erosion from the acidity of the rain. It is put at great risk, with acid rain falling on the Yucatan peninsula and much of southern Mexico fast bringing destruction to the temples, colourful murals and aunting megaliths of the ancient Maya civilization. Of course, this puts historical sites such as Chichén Itzá in danger. With increasing industrialization, the amount of harmful greenhouse gasses has skyrocketed. This causes acid rain falling onto the Yucatan peninsula to possibly be intensified, causing the Chichén Itzá to be at risk of total destruction due to acid rain.

Additionally, archaeological data and evidence of climatic change are used to suggest that the collapse of Uxmal and Chichén Itzá in the Northern Maya Lowlands was the result of long and recurrent drought episodes in the eleventh century. Although environmental evidence indicates that drought episodes might have begun in the ninth century, they gradually increased in frequency through the eleventh century and generated devastating effects on the late Terminal Classic period civilization.

Thus, it is easy to imagine how vulnerable this historical wonder of the world is today, with the entire world now facing the consequences brought about by global warming, various historical sites are currently facing threats with the Chichén Itzá being an example.

The 12 Apostles. A sight to behold. They were formed 20 million years ago by the severe conditions of the Southern Ocean. Gradually, caves in the cliff face developed into arches, and these arches collapsed and limestone stacks were left behind. However, what was once a picturesque scenery has indisputably been reduced to a mere seven stacks.

The winds are getting stronger and that accounts for the higher wave conditions, and also those low-pressure systems are tracking further to the south and what that does is it means the waves will come from a slightly more southerly direction. Since the wave direction changes there is a change in orientation of the coastline as well. With a long beach, when wave conditions change two or three degrees the alignment of the beach will change. This change in orientation of the coastline will cause erosion in some parts of the beaches. With rising sea levels, waves are washed further into the shore, increasing the rate of erosion of the Apostles. This can be seen from how 5 of the Apostles have been completely washed away. Global warming has also resulted in the rise of temperatures, which in turn increases the rate of degradation of the 12 Apostles. In fact, in a number of spots, the road is now only metres from the tide line. This is a very beautiful and fairly unique experience for driving and sightseeing. However, once the ocean breaches the road, locals will be cut off and tourists will miss out on this iconic journey.

In conclusion, climate change has already affected and eroded 5 of the 12 Apostles, and it is not going to be long before all the apostles are eroded. Therefore, we must play our part in environmental conservation to protect these natural scenic sites.

We have chosen to make a model of the Colosseum ,which is one of the wonders of the world, out of recycled amazon prime box. and designed the design using markers.

Global warming constantly lowers humidity levels in southern Europe which will lead to an increase in the amount of salts deposited on marble and limestone, potentially weakening and breaking the structures of the Colosseum.

We decided to do the poem in the form of the "divide sign". This is because currently, people are divided abut this issue and opposing viewpoints have caused many conflicts among us. Many also seem to believe that they are doing their due diligence when in fact, more can be done. We believe that if we all unite as one, this seemingly unachievable goal will become our achievable goal. Thank you.

increasingly high temperatures linked to climate change, as well as wilder weather, heavy droughts and flooding, are taking a growing toll on the ancient stonework. this is a result of climate change and it is serious because it has led to the deterioration of cultural & historically rich monuments

Stonehenge is being threatened by climate change because climate change is the increase in the Earth’s surface temperature, creating warmer weather conditions that allow animals such as badgers and moles to flourish. Underground activity of such animals would then increase, thus increasing the risk of the Stonehenge shifting around and even crashing.
The extreme temperatures brought about by climate change also result in more severe weathering. The rise and fall in temperatures cause the expansion and contraction of the stones which weakens their structures and they crumble more easily. Climate change has brought about effects that threaten the stability of Stonehenge.

We chose the great barrier reef as people are constantly destroying the oceans by throwing their trash into the oceans inconsiderably. Other than that, global warming that is caused by people's emission of greenhouse gases is warming the ocean. This is incredibly hurtful for the ocean as it endangers the sea life, more specifically the corals reefs and especially the great barrier reef as it is a wonder of the world and should be protected. The Great Barrier Reef has lost over half of their corals due to climate change, which causes the bleaching of corals, therefore in order to draw attention to this issue that is not very known to many people.

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

Due to global warming, the world faces warmer winters that will likely boost the populations of the burrowing animals. In the report issued by the scientists, it says that the warmer winters will cause the animals to reproduce more, causing the ground to become more disturbed due to the rise in activity underground near the archaeological grounds thus, making the stonework less stable and more likely to fall.

The hotter and drier summers due to the increased average temperatures would also increase the number of visitors to the ancient sites. Currently, there are about one million visitors a year, which increases the disturbances underground possibly risking the Stone henge.

Global warming also causes increased humidity and the warmer and wetter ground conditions mean that it is the ideal time for earthworms to reproduce. Worms are a major part of the mole’s diet, thus creating an endless cycle of reproduction between the animals. The soft, wet soil also makes it easier for the animals to dig than does the drier ground which causes the ground to be more disturbed and so it could cause the Stone henge to be uprooted.

With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapour is evaporated into the atmosphere it becomes fuel for more powerful storms to develop. If storms become worse, and the sea levels rise, the British heritage sites might be washed right out into the sea with the higher tides.

Hence, in many ways, climate change could risk one of the oldest historical sites in the world being destroyed.

We used recycled materials ranging from a used, broken balsa wood plane to toilet rolls and egg cartons. Balsa wood is a good choice because of its high strength to weight ratio and ease of shaping.

Climate change leads to global warming. As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent. Additionally, carbon dioxide absorbed into the ocean from the atmosphere has already begun to reduce calcification rates in reef-building and reef-associated organisms by altering seawater chemistry through decreases in pH. Since the late 18th century, the ocean has absorbed about 30% of the carbon humans have generated, decreasing its pH level. This process is called ocean acidification. Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns.

When combined, all of these impacts dramatically alter ecosystem function, as well as the goods and services coral reef ecosystems provide to people around the globe.

Climate change is also increasing the frequency and intensity of severe weather events. Coastal regions like the Great Barrier Reef are particularly exposed to damaging cyclones, flooding and storms. Between 2004 and 2018, 10 cyclones of category three or more crossed the Great Barrier Reef, causing significant damage to coral reefs.

Our class has chosen to create the Great Barrier Reef model! It is home to many species of marine life, generates clean air and protects the coastline. However, due to the pollution of the ocean, the Great Barrier Reef experiences coral bleaching and is gradually losing its wonder.

Our product is made up of recycled materials, like shredded plastic bags to represented the plastic waste deposited in the ocean every day. We also used cut up posters and newspaper to create the corals, as well as some small marine life like lobsters and fishes. This is to emulate the ocean scene of animals having to live with a polluted environment.

The Great Wall of China, which has stood for more than two millennia, has recently experienced the collapse of two chunks of its structure: one due to climate changes causing erosions of the land surrounding the wall and the other caused by mining taking place in nearby areas.

Extreme weather conditions have caused approximately 25 miles of a section of the wall built during the Han dynasty to erode in recent years. Sandstorms have caused the bricks of packed earth to wear down, and, over time, “also cracked the wall and caused it to collapse or break down,” archaeologist Zhou Shengrui says.

Another section of the wall, which was considered the “crust of the cream” of the Ming dynasty, has suffered a 700-meter (or 2,300 feet) loss because of a network of underground mines in a secluded area of the Hebei province. Although the mines are not located directly beneath the wall, the nearby hollowed chambers beneath the earth are affecting the structure’s stability.

This is the reason why we decided to make the Great Wall of China with recycled materials as we think that it is crucial to bring light to the fact that even such a great wonder of the world can be affected by climate change with severe repercussions.

The great barrier reef is in great danger due to rising sea temperatures. The corals cannot tolerate the high temperatures caused by global warming, causing them to die and be bleached. In order to protect the great barrier reef, many researches have tried scientific methods to mitigate the impacts of global warming. However, we should also do our part to fight against climate change. Thus, we decided to construct a great barrier reef in order to bring light to this issue and call everyone to play their part in making a difference in through small efforts, which are extremely impactful as a collective. This HUSH STEM project is just one of many steps that we, as RGS students, can take to impact change. Thank you. #ilovehushstemweek

Our class built a model of the colosseum, using recycled materials including used styrofoam, old cardboard and old worksheets. The rough surface of the styrofoam represents the slow erosion of the colosseum’s walls over time, as there is an increase in acid rain triggered by climate change. Acid rain occurs when greenhouse gases such as carbon dioxide, sulfur dioxide and nitrogen oxides dissolve in the rainwater, which corrodes the marble and concrete surfaces of the colosseum. If we do not decrease the use of fossil fuels and take active steps to reduce the greenhouse gases emissions in our daily life, many important and historical landmarks such as the colosseum will be eroded away to nothing.
