Taiwan is located between the world's largest landmass, the continent of Asia, and its largest ocean, the Pacific Ocean. The Tropic of Cancer passes through the island of Taiwan, giving it a subtropical and tropical oceanic climate. High temperatures and rainfall and strong winds characterize the climate. Because of Taiwan's position in the Asian monsoon region, its climate is greatly influenced by monsoons as well as by its own complicated topography. The annual mean temperatures in the lowlands are 22–25°C, and the monthly mean temperature exceeds 20°C for eight months starting with April each year. The period from June to August is the hottest season with mean temperatures of 27–29°C. Temperatures are cooler between November and March; in most places, the coldest monthly mean temperature is above 15°C. The climate is mild rather than cold and temperatures only fall dramatically when a cold front affects the region. Average annual rainfall in the lowlands of Taiwan is in the range of 1,600–2,500mm. Due to the influences of topography and the monsoon climate, the rainfall differs greatly with different areas and seasons. In mountainous areas, average rainfall may exceed 4,000mm/yr. Rainfall is generally higher in mountainous areas than in lowland areas, higher in the east than in the west, and higher on windward slopes than on the leeward side. The northeast monsoon prevails during the winter; this is the rainy season in the north though rainfall is not intense. But the same winter period is the dry season in the south. During the summer, the southwest monsoon prevails, often giving rise to convective thunderstorms and bringing intense and copious rainfall. With added downpours brought by typhoons, this season often accounts for over 50% of annual rainfall in the south so that central and southern regions often suffer greatly. Relative humidity on the island of Taiwan, surrounded by ocean, is high, usually measuring in the range of 78–85%. In the north, relative humidity is higher during winter than during summer. The situation in the south is the opposite. Over the past 100 years, the rainfall in the north has increased, while the rainfall in the south has decreased. The trend is not as consistent as that of the temperature change (Environmental Protection Administration, Executive Yuan, R.O.C. (Taiwan), 2002).

Global temperature has risen by 1°C since 1900, while since the 1990s the Arctic has recently experienced an accelerated warming of about double the average rate of global warming. Nearly all climate scientists agree that the main cause of this temperature rise is ever-increasing accumulations of ‘greenhouse gases’, especially carbon dioxide and methane, within our atmosphere. Sea level rise could easily exceed one metre this century under ‘business as usual’. However, global warming is not just about rising temperatures, melting ice and rising sea levels, but it also affects the frequency and severity of many extreme weather events. Planetary warming is not a uniform process, can spring surprises in regional climate change and is probably linked with the tendency for Northern Hemisphere mid-latitudes to have more extreme (variously hot/cold/dry/wet) weather, especially during the recent period of rapid Arctic warming. There is overwhelming scientific evidence that human activity through enhanced greenhouse gas emissions is largely responsible for recent climate change and accompanying extreme weather, and we are already clearly seeing these changes. However, it is equally evident that, although initial remedial steps are being taken, finding an adequate solution will not be easy unless much larger changes are made to the way in which we all live. Limiting global warming to 1.5°C above pre-industrial temperatures would require global carbon dioxide emissions to decrease by approximately 40–60% by 2030 relative to 2010 levels. This can only be achieved through a collective solution that fully involves diverse communities, among them religious stakeholders.

The purpose of this study was to investigate the trends of climate change and their impact on businesses in Kenya’s Public Listed Companies (PLCs).

Out of 66 PLCs, the researchers interviewed 10 companies, and therefore obtained a 15% sample. The methodology was utilization of both primary and secondary data and by use of a combination of the structured and unstructured interviews.

The findings indicated that, although climate change issues are mentioned or implied in strategic plans and core values, they rarely however, translate to normal or day-to-day conversation or operation of the businesses. PESTEL factors are cited as having a very positive impact on businesses that are technological and economic, contrary to environmental/climate change factors which have a more negative than positive effect on the business. Electricity outages/shortages will have serious impact, while agricultural, tourism, insurance, and aviation sectors are likely to be most severely affected by climate change. The hypothesis that climate change is affecting all businesses was accepted while that stating that climate change is significantly impacting businesses negatively rather than positively by increasing operating costs which may result to closure if not mitigated by 2030 was rejected.

Companies should not adopt a “business as usual” attitude but invest in training on effects and strategies for mitigation as well as adaptation and translate climate issues into action as well as create synergy in tackling climate change issues.

The research is valuable to environmentalists, meteorologists, business community, academicians, as well as scientists and scholars alike both nationally and internationally.

While climatic conditions are believed to have some influence on triggering conflicts, the existing empirical results on the nature and statistical significance of their explanatory role are not conclusive. We construct a dataset for a sample of 139 countries which records the occurrence of an armed conflict, the annual average temperature and precipitation levels, as well as the relevant socioeconomic, demographic, and geographic measures over the 1961–2011 period. Using this dataset and controlling for the effect of relevant nonclimate variables, our comprehensive econometric analyses support the influencing role of climatic factors. Our results are robust and consistent with the hypothesis that climate warming is instrumental in raising the probability of onset of internal armed conflicts and suggests that, along with regulating population size and promoting political stability, controlling climate change is an effective factor for inducing peace by way of curtailing the onset of armed conflicts.

The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) (Intergovernmental Panel on Climate Change, 2007) of 2007 concluded that most of the warming of the climate is very likely driven by human activities that increase greenhouse gas (GHG) concentrations in the atmosphere. Activities such as burning of fossil fuels for power generation and in vehicles, as well as increasing deforestation, result in emissions of four long-lived GHGs: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and halocarbons (a group of gases containing fluorine, chlorine, or bromine). The report projects that by the end of the 21st century global temperatures could rise by 1.1–6.4°C over 1990 levels, while global mean sea levels could rise by 18–59cm, depending on future scenarios of varying global emission levels. This is likely to adversely impact ecosystem resilience, putting many plant and animal species at the risk of extinction. Sea level rise and coastal erosion coupled with temperature extremes, heat waves, and heavy precipitation events that are projected to become more frequent will affect the health and well-being of millions of people around the world.

In the southern hemisphere, the Antarctic continent is also experiencing a net loss in ice from the extensive glaciers and ice sheets that cover it. However, the connection between changes in Antarctic ice sheets and the global warming trend are much more uncertain than in the Arctic. The complex of changes in the Antarctic climate and the ice sheets are described in a later section of this chapter.

Ladakh is an isolated arid environment in the Western Himalayas whose population relies mainly on glacial melt water. If the predicted adverse impacts of climate change occur, rising temperatures would accelerate the retreat of glaciers and place immense stress on the traditional Ladakhi agriculture and way of life. Very few studies in hydrology and glaciology currently document physical processes happening in Ladakh and only one project has combined climate data based upon measurements of temperature and precipitation, collected by the Indian Air Force in Leh town, and perceptions of local communities in order to explore the potential impacts of climate change in the area. This information constitutes the basis for climate change-related interventions of nongovernmental organizations (NGOs), both local and international, and could help inform any future climate modeling. However, the quality of this data can be questioned on several points, it terms of accuracy, availability and, most importantly, usefulness. Moreover, this chapter discusses the relevance of this kind of data when the focus is placed upon the adaptation of local communities to global environmental changes where climate change may not be the primary cause. For instance, the region is also currently undergoing a rapid transition from subsistence farming to a market-based economy due to the integration of Ladakh into India and the growing influx of tourism. When addressing the broader context of environmental change, reliable, accurate, and available climate data and models could be useful only if used as part of a holistic approach. This approach requires research and interventions to combine scientific information with local knowledge and perceptions about the impacts of climate change to root the physical data in a “real world” context. It must also acknowledge other drivers of environmental changes such as unsustainable development.
