Peru is a nation composed of heterogeneous ecosystems including the coastline of the Pacific Ocean, deserts, the Andes Mountains including the glacial regions, and the second largest portion of the Amazon Forest Basin (US AID, 2011). Its heterogeneity creates such a dire situation for Peru in terms of climate change and the effects it has on each individual system as well as the effects on wildlife and human occupants that live in these regions. In Peru, the climate changes that have been taking place have led to several disastrous outcomes that include not only draught, but have also led to depletion of the Amazon Rain Forest, an increase in disease, extreme temperature changes, glacial ablation, extreme weather, and changes in the nations oceans which are home to many species found only in this region. These changes in climate have affected the entire country from the Amazon Basin to the farmlands of Cusco. Are the climate changes occurring in the region only human induced, or are there other naturally occurring forces that are contributing factors as well? What changes and policies are being implemented in order to halt or slow the process of climate change in this country and what is the severity of problems that could arise if nothing is done?
The most immediate issue caused by climate change in Peru is the effect of the change on farmlands and food production in the country. Although agriculture only accounts for about 7 percent of the GDP for Peru, around 23.3 percent of the working population partakes in agricultural practices (US AID, 2011). Farming regions such as Cusco and Piura have experienced a drop in crop production by nearly half in recent years (Hufstader, 2009). Eighty percent of the farmland in these region...

It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
In order to get a comprehensive picture of these issues, this chapter reviews literature on climate change and vulnerability. It begins by defining climate change and analyzing global climate change in general and its impacts on local smallholder farmer’s livelihoods in a developing country such as Zimbabwe. Lastly the chapter also assesses the measures of adaptation which smallholder farmers can use to increase their coping capacity and resilience to climate change and variability.
In recent decades, the contentious issues surrounding climate change and the corresponding effects it likely exerts upon contemporary civilization has developed to become one of the most pressing areas of concern afflicting humanity (Armstrong, 1). Currently, climate change has started to demonstrate its potentially calamitous consequences upon human subsistence practices, and has even begun to alter the very environments that entire societies reside in, theoretically endangering them in both instances (Armstrong, 1). Though the hindrances inherent in climate change are potentially devastating to the preservation of modern society, the problem of climate change itself is not one that is exclusive to the contemporary era. Rather, the harmful
The clock is ticking! Global Co2 emissions have increased exponentially since the industrialization of today’s developed world. Emissions have now passed the absorptive capacity of the earth and are accumulating in the earth’s atmosphere, warming the surface of the earth and inducing localized climatic changes. Climate change is often a localized issue. Many regions of the world will continue to become hotter, while others may experience highly variable weather patterns. Climate change poses a serious threat to ecosystems, economic sectors, and human welfare. Although almost entirely caused by the developed world, climate change will disproportionally affect the world’s poor.
...ld. Globally, more intense hurricanes and downpours could cause billions of dollars in damage to property and infrastructure. Declining crop yields due to prolonged drought and high temperatures, especially in Africa, could put hundreds of thousands of people at risk for starvation. The Ski resorts located in the lower altitudes of the Swiss Alps have difficulty obtaining bank loans because of declining snow.
The causes of climate change are also known to them that though it is not only the human action playing role but it is the main cause of climate change. The effects of climate change does include harm and loss of environment and organisms but it also has impact on the human health. Semenza (2014) displays an assessment report which states that throughout the 21st century, the rapidly occurring climate change will lead to increase in number of humans with ill health in many regions mainly in those of developing countries where citizens face low income. Semenza (2014) also mentions how there are physiological limits to intense heat exposure and the global climate change will turn some parts of the world which are currently highly populated into uninhabitable even if the global temperature rises by 7 degrees Celsius. Johnson (2014) states how El-Niño-related hydroclimate variability will lead to being intensified under global warming mainly in areas as southern Asia which are already stressed by different droughts, floods, and crop yields. Dettinger, Udall, and Georgakakos (2015) mentions how climate change puts risk and threat on water resources in the western United States to an extent that no other part of the country matches it. Dettinger, Udall, and Georgakakos (2015) also states how recent research and studies strictly point a limited number
These nations “with the least resources have the least capacity to adapt and are the most vulnerable to climate change damages, just as they are more vulnerable to their environmental stresses” (Ravindranath et al., 2002). The largest problems will stem be from a lack of water in already water scarce areas, a decline in the crop yields and health issues relating to the climate change. Heat will become a major source of harm and diseases will increase as well (Ravidranath et al,

It’s impossible for poor rural women and their communities to cope with the effects of climate change when both are perpetually in crisis mode. Their capacity to adapt must be strengthened. Compared to men in poor countries, women face additional cultural, social and economic barriers that make them more vulnerable to climate change. They have limited access to productive assets such as land, credit, and extension services, and they continue to lack voice and decision-making power on agriculture policies and programs. As a result, they are in many cases the first casualties of volatile climate conditions, falling into food insecurity and malnutrition. This reality demands a gender analysis toward climate change mitigation” (Hunger report 22) This being said, our increase in involvement improving women’s rights for education, ability to voice their opinions and breaking cultural norms that restrict them will result in less stress as well as more food. This will break the cycle of poverty. Educating women agriculturally will benefit them and increase their involvement in growing and cultivating produce, which will lead to them selling what they make and gives in increase in their home’s
We live on an incredibly large planet. Even broader than the size of the planet are the amount of changes and relationships between humans, animals, environment, weather, and the effects of each. Many times with busy schedules and modern lifestyles we forget the interaction that goes on between any number of concepts or ideas. We fail to realize that a specific weather occurrence in the Pacific Ocean can have an effect on every day life in the United States. El Nino is one of the largest scientific phenomenons that scientists have ever explored. The main concepts of El Nino are very simple and there are many variations, causes, affects, and relationships to study.
Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment.
Since 1960s both minimum and maximum temperatures have exhibited a rising trend; with minimum increasing by a range of 0.7-2.0 degrees Celsius and maximum by 0.2-1.3 degree Celsius varying by region and season. Notable also is variability of rainfall patterns such as below normal rainfall in the long rains season and more during the short rainfall season, some regions have recorded more intense rainfall and downpours that have resulted to floods and infrastructural impairments. Extinction or near extinction of flora and fauna, changes in flowering and maturity patterns in crops are all attributable to climate change. These changes have had and are expected to have far reaching impacts on the economic sectors of the economy. Some of the expected sectoral impacts are discussed
