How Did African Climate Change

With the climate change it allowed most animals and plants to survive. Now people didn’t have to go seek for food it came to them.

After the last ice age, the European continent was transformed as climate warmed and sea levels rose. Increased rainfall and warmer temperatures allowed communities to depend more on plant foods and exploit their surroundings. Communities took advantage of new resources and grew in size and complexity as hunter-gatherers became farmers.

One of the first catastrophe that came and helped end the bronze age was climate change. Around 1200 BC many regions in Afro-Eurasia were used to having rapid population growth and prospering agriculture life. During

After viewing the results of the archaeological skeletons and coexisting Europeans, there were contradictions in the genes that dealt with skin, hair and eye pigmentation. Over hundreds of thousands of years, the earliest ancestors had dark pigments but scientists believe that over 50,000 years, humans slowly started to relocate to northern latitudes. Due to the limited levels of sunlight, their pigments slowly started to change to a lighter and lighter shade. As humans, is it essential to receive vitamin D from UV sunrays. Since ancestors did not eat and drink vitamin D fulfilled food

Agriculture is one of key industries in both sub-Saharan Africa and Australia. In the recent few decades, agricultural production is under serious threat from severe drought, and the drought has triggered a series of chain-reactions involving important economic and social issues. To cope with various challenges, sub-Saharan Africa and Australia have already taken multiple approaches.

Hieroglyphs can be considered one of the oldest forms of literature; Egyptians developed this technology at around 4,000 BC. Reasons for creating hieroglyphs are art, and communication (Mattessich). Parallel to that, farming was another type of technology that was being developed along the north of Africa and the river Nile, by the upcoming kingdom of Africa. Nubia (modern day Sudan) also gave rise to another kind of technology in term of agriculture, the cattle herding, their location made it easy to feed animals because it was tropical and had lots of vegetation. Hunter gathers were living since the beginnings of times, so this is not a new developed technology but it is significant to say that the rest of Africa was occupied by them (Britton).

Our bodies are in a “can’t live with you, can’t live without you” relationship with the sun. Too much sun can fatally damage our skin, causing skin cancer, hence the “can’t live with you” part. Meanwhile, all organisms need the sun to live. Humans need the sun for oxygen, which is a result of plants going through a process called photosynthesis. Photosynthesis is a process that turns carbon dioxide and water to glucose and oxygen, using sunlight. The plants need glucose for energy, while humans need oxygen to breathe. Additionally, natural sunlight helps our bodies create vitamin D and destroy our bodies’ reserves of folic acid. We need a sufficient amount of vitamin D to live but we also need folic acid as well.

In the face of climate change Sub-Saharan Africa is confronted by two main challenges of food security and water availability for human and agricultural use. These challenges are projected to increase in the coming years compounded by extreme droughts and extreme flooding in some areas. Rain-fed agriculture is the main livelihood for a majority of small scale farmers in SSA. Their main farming systems focus on the “ major crops”(maize, wheat, rice and beans) However, strategies to cultivate these crops in the region are no longer sustainable due to reliability on finite resources, high input load and vulnerability to climate change. A key alternative strategy to adapt to a changing climate is the development and promotion of Orphan crop species

Africa and America are two very different continents but can still be compared throughout their history. After previously researching Americas history it came about that a vital part of the American culture come down the native people deciding to move or remain in one place due to a huge climate change, a very similar thing happened in West Africa. In about 5500BC it was the ‘beginning of the desertification of north Africa, which ultimately lead to the formation of the Sahara desert from land that was previously savannah, though is still wetter than today. It's possible this process pushed people in the area into migrating to the region of the Nile in the east, thereby laying the groundwork for the rise of Egyptian civilization.’ [https://en.wikipedia.org/wiki/Timeline_of_environmental_history].

Africa used to be full of life and the population was vast, due to the events that took place Africa no longer has the resources to trade with other countries. The impact of the slave trade was large enough to deny Africa from all of its greatness. Africa is now known for hosting small villages that are very poor and underdeveloped, Africans are unable to fend off disease and they cannot afford the supplies and materials for cures. They were drained of many resources not just their people, Africa

The episode I watched from “How the Earth Was Made” was the Sahara Desert episode. In this episode I found it shocking how much the landscape has changed in the past millions of years. By studying the landscape, erosion of rocks, fossil records, and ocean floor sediment scientists have discovered many things about how and why the landscape has changed. Scientists have discovered that over four million years ago the Sahara Desert was originally an ocean. Fossils of whales, other sea creatures, and mangrove tree roots were found on the site. Scientists predict that because of plate tectonics the ocean started to dry up and trapping ocean creatures in bodies of salt water that were slowly shrinking. By observing ocean sediment scientist could

Climate change slowly began in the 1800s when fossil fuels started to gain popularity. Fossil fuels made former

I think that the most interesting connection between historical and recent climate change is is the cycle. Over the last 600 million years or so, the earths climate has gone through many cycles, some short and relatively mild and some long. The climate change in the past were natural in origin and the only difference between then and now is us. In the past the climate change was natural cycle, climate change that took place over millions of years can be much larger and have different causes such as continental drift and orbit (IPCC, 2007). The changes experienced today is different and can be seen on a centennial time scale. I think the most interesting connection between historical and recent climate change is like many others will probably

Rainfall patterns changed around 11,700 to 12, 00 years ago due to the ice age. There where advances and retreating of ice caps or ice sheets. At the same time monsoons, rains over deserts transformed the deserts into habitable land.

Well it all starts a long way back in this little place next to asia called Europe, it's kind of out of the way, you probably have never heard of it. It isn't like our entire nation sprouted out of it. But along comes these Europe people and they decide to shake Africa clean of all of its natural resources. You know, just the non valuable things like gold, food, and human beings. And on top
