This understanding is crucial because it allows decision makers to place climate change in the context of other large challenges facing Africa and the world. This study reviews the causes and effects of climate change on agriculture in Africa. The main interests are findings concerning the present ...
Causes of climate change The earth's climate is dynamic and always changing through a natural cycle. What the world is more worried about is that the changes that are occurring today have been speeded up because of man's activities. These changes are being studied by scientists all over the...
West Africa was hit with a severe drought following a humid heat wave that drove temperatures to record levels in February. 西非遭受了严重的干旱,此前潮湿的热浪使2月份的气温达到了创纪录的水平。 Scientists from the World Weather Attribution group say the unusually hot weather was made ten times...
which would weaken their immune systems and make them more susceptible to disease. Another possibility is that temperature shifts caused by climate change may create environments more favorable for the growth of chytrid fungus. In addition, climate...
At times they may find relief by hunting big game in Africa, or by flying round the world, but the number of such sensations is limited, especially after youth is past. Accordingly the more intelligent rich men work nearly as hard as if they were poor, while rich women for the most ...
the production and use of fertilizers and manure for growing crops, and the use of energy to run farm equipment or fishing boats, usually with fossil fuels. All this makes food production a major contributor to climate change. And greenhouse gas emissions also come from packaging and distributing...
CO2 content in the oceans also contribute to a warm climate and also can contribute to sea level rise. DRIFTING OF CONTINENTS-Africa and South-America were joined together, about 200 million years ago. At that time scientists believe that the earth is not like what we are seeing today, but...
Chytrid fungus has now been found in more than 400 amphibian species and has been associated with population die-offs in North, Central, and South America, as well as in Africa, Europe, Australia, and New Zealand. While it is clear that chytrid fungus is the immediate cause of many rapid...
2. What increased the likelihood of the unusually hot weather, according to scientists from the World Weather Attribution group? 3. Name one consequence of the drought in West Africa. 4. True or False?Big companies haven’t yet had to increase theirprices. ...
forcing amphibians to congregate in smaller bodies of water, facilitating the transmission of disease. All these factors point to a possible connection between climate change and disease, but to date the necessary research has not been done to determine if any of these inks are actually operating....
