How Did African Climate Change

1. Global warring 2. The increase in the temperature 3. The south the farmers burn rain forest 4.

When traders bought they bought low and sold high. Traders would weight their gold when paying and the African people would buy at high prices because they wouldn't weigh the gold. This also allowed nations too have a import and export tax giving the government extra income. This made people want to come to africa and while they were there they would also want to buy goods they can't normally buy such as Ivory and leopard skin. This lead to people killing most of the leopards and elephants for their skins and tusks. This over killing led to the population of animals decreasing. Causing them to kill animals faster than they are being born. This meant that you children and your grandchildren would have to go further too kill animals to make money they need to

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.

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.

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

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).

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

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, global warming, greenhouse effect—even if you only watch the news periodically, these are phrases that you have most likely become aware of. In short, climate change is the change global and regional patterns regarding climate; this is due to possible changes in the Earth’s axis, human activity modifying the composition of the atmosphere, or geographical activity such as volcanic eruptions [1]. Many have speculated and argued whether climate change actually exists. Regardless of your opinion, a staggering amount of scientists have accepted climate change as a reality. In fact, the much-admired astrophysicist Neil deGrasse Tyson claims that individuals denying scientific facts is the “beginning of the end of an informed democracy” [2]. The article Climate Change: No Hiding Place supports Neil deGrasse Tyson’s notion stating “those who doubt that greenhouse gases are quite the problem they have been cracked up to be by most of the world's climatologists” [3]. While it may be difficult to see climate change presently, there are many indicators of its existence with the higher temperatures and acidity levels in the ocean, the melting of Arctic ice caps,

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

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

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.

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
