Tonga is one of the world’s most exposed countries to climate change and natural disasters. It suffered the highest loss from natural disasters in the world (as a ratio to GDP) in 2018 and is among the top five over the last decade (Table 1). Climate change will make this worse. Cyclones will become more intense, with more damage from wind and sea surges. Rising sea levels will cause more flooding, coastal erosion and contaminate fresh water. Daily high temperatures will become more extreme, with more severe floods and drought.

The Impact

This article analyses the profound and rapid climate changes that have taken place worldwide in the past two decades and their effects on modern enterprise. Reducing greenhouse gas emissions and developing strategies to adapt to and counterbalance future impacts of climate change sustainably are among the most pressing needs of the world today. Global temperatures are predicted to continue rising, bringing changes in weather patterns, rising sea levels, and increased frequency and intensity of extreme weather events. Such climatic events can have a major impact on households, businesses, critical infrastructure and vulnerable sections of society, as well as having a major economic impact. Therefore, society must prepare to cope with living in a changing climate. The effects of a changing climate have considerable impacts on modern enterprises. In some parts of the world, these impacts are increasingly becoming evident.

Rising Sea Levels

Climate change is one of the most serious risks facing humanity. Temperature rises can lead to catastrophic climate and natural events that threaten livelihoods. From rising sea levels to flooding, bush fires, extreme temperatures and droughts, the economic and human cost is too large to ignore. More than 190 world leaders got together in Glasgow during November 2021 at the UN’s COP26 climate change summit to discuss progress on the Paris Agreement (COP21) and to agree on new measures to limit global warming. In Paris, countries agreed to limit global warming to well below 2° and aim for 1.5° as well as to adapt to the impacts of a changing climate and raise the necessary funding to deliver on these aims. However, actions to date were not nearly enough as highlighted by the IPCC (2018) special report. The world is still on track to reach warming above 3° by 2100. As evident from figure 1, global temperatures have been on a steadily increasing path since the start of the 20th century and this process has substantially accelerated since the beginning of the 1980s. This has been unevenly distributed, with temperatures in the Northern hemisphere being a full 1°C higher than for the 1961–1990 average, whilst temperatures in the Southern hemisphere have increased by almost 0.5°C.

In the previous chapter 3 the focus of the presentation has been on the implications of climate change, as felt globally, for the environment and human societies in developing as well as in developed countries. As noticed there, the Stern Review’s conclusion that “climate change will have increasingly severe impacts on people around the world, with a growing risk of abrupt and large-scale changes at higher temperatures” (Stern Review, 2006) is shared by most scientists and governments. The Review warns that “a warmer world with a more intense water cycle and rising sea levels will influence many key determinants of wealth and well-being, including water supply, food production, human health, availability of land, and the environment” (Stern Review, p. 84).

<p>The world is facing a future where geoscience issues with significant social impact are increasingly central, including climate change, clean water, energy and resource management (e.g. mining, fracking), and natural disasters. The disposition of the next generation of citizens, as future voters and as future scientists, is vital if the world is to meet the challenges of rising temperatures, rising sea levels, and rising incidences of natural disasters. This paper arises from ongoing educational research undertaken in Irish secondary schools, examining student engagement with and understanding of geoscientific topics. Earth Science is included in the new Science syllabus in Ireland for 12 - 15 year old students (lower secondary level), but so far, no one has studied Irish students’ attitudes towards Earth Science. This is a mixed-methods study involving a survey of secondary schools in Ireland, including urban and rural, and mixed- and single-gender schools. Students representative in age and demographics of the participants are included as consultant voices at multiple stages in the study. Preliminary results from this study will be discussed in detail, focusing on student attitudes towards Earth Science as global and Irish citizens; how they conceptualise human interdependence with and on the planet; and how they consider themselves in different ways connected to or independent from the Earth, the study of Earth Science, and students or children their age elsewhere on the planet facing similar challenges in the era of climate change. </p>

Future Consequences

As the scientists indicate in their analyzes, about 60% of vertebrates on Earth have extinct since the industrial revolution. The inevitable climate catastrophe in the coming decades will bring even more noticeable damage. Due to the pres-ence of the human species in the world and its unrestrained expansion, the eff ects of Homo sapiens activity aff ect almost all ecosystems. Snowless winters, rising sea levels or extremely high temperatures are symptoms of a disaster that we are unable to ignore. This article briefl y discusses the most signifi cant threats to ecosystem services, the eff ects of careless human activity, and their current as well as future consequences, broken down into individual “sectors” of human activity. The current geopolitical situation regarding climate change and its impact on the world will also be presented. This article is mainly based on the 2019 IPBES report and reports from WWF and other entities dealing with climate change.

Failure to take climate change seriously enough has resulted in the world now facing a climate emergency, with rising global temperatures, melting polar ice caps, increasingly frequent and severe storms, floods and droughts, and rising sea levels. Despite being the first country in the world to set statutory carbon emissions reduction targets (in the Climate Change Act 2008), the UK government since 2012 has fallen increasingly behind, even by its own standards. This paper details what this has meant in terms of specific policies and identifies some of the reasons for this policy failure: in particular, a negative attitude towards regulation and a return to a reliance on market forces, plus an overriding concern to continue with ‘business as usual’, in terms of support for fossil-fuel industries and ever-increasing energy demand and supply. Ironically, this has resulted in a situation where radical solutions seem even more necessary and more urgent.

Life On Earth

Science has shown us that since Earth’s creation, climate has been affected by natural occurrences,both within and outside the climate system, but in recent years, climate is also being affected by actions andinactions of the human race. Climate system changes affect all life on earth, but fisheries are affected inparticular, because almost three-quarters of the Earth’s surface is water and home to a variety of aquatic life.Changing weather is producing more droughts, floods, rising sea levels, salt water intrusion of fresh water,acidity in the oceans and ocean warming. This paper discusses how climate change is affecting both marinelife in the oceans and aquatic species in fresh water, as well as the effects of these changes on the seafoodsupply chain and other revenue sources in coastal areas. Factors causing climate change and actions needed tomitigate these changes are also discussed.

The storm came on the night of 31 October. It was a full moon, and the tides were at their peak; the great rivers of eastern Bengal were flowing high and fast to the sea. In the early hours the inhabitants of the coast and islands were overtaken by an immense wave from the Bay of Bengal — a wall of water that reached a height of 40 feet in some places. The wave swept away everything in its path, drowning around 215,000 people. At least another 100,000 died in the cholera epidemic and famine that followed. It was the worst calamity of its kind in recorded history. Such events are often described as "natural disasters." This book turns that interpretation on its head, showing that the cyclone of 1876 was not simply a "natural" event, but one shaped by all-too-human patterns of exploitation and inequality — by divisions within Bengali society, and the enormous disparities of political and economic power that characterized British rule on the subcontinent. With Bangladesh facing rising sea levels and stronger, more frequent storms, there is every reason now to revisit this terrible calamity.

Natural disasters represent a latent threat for every country in the world. Due to climate change and other factors, statistics show that they continue to be on the rise. This situation presents a challenge for the communities and the humanitarian organizations to be better prepared and react faster to natural disasters. In some countries, in-kind donations represent a high percentage of the supply for the operations, which presents additional challenges. This research proposes a Markov Decision Process (MDP) model to resemble operations in collection centers, where in-kind donations are received, sorted, packed, and sent to the affected areas. The decision addressed is when to send a shipment considering the uncertainty of the donations’ supply and the demand, as well as the logistics costs and the penalty of unsatisfied demand. As a result of the MDP a Monotone Optimal Non-Decreasing Policy (MONDP) is proposed, which provides valuable insights for decision-makers within this field. Moreover, the necessary conditions to prove the existence of such MONDP are presented.
