Life without the Beach: Projected Sea Level Rise and its Impact on Barrier Islands Along the East Coast, USA Abstract As climate change is becoming a global issue, the impact of sea level rise is increasingly becoming a threat to humans, wildlife, infrastructure, and ecosystems. To evaluate the effects of sea level rise on barrier islands and coastal regions, we studied future projections of sea level rise at Ocean City and Assateague Island, Maryland. -
Extinction Is Inevitable in the Globalized World
Extinction is inevitable in the globalized world Aishwarya Maheshwari1 1Banda University of Agriculture and Technology July 23, 2020 Abstract No abstract - Extinction is a natural process and every species on this planet has an expiration date except Homo sapiens because we are extending our expiry at the cost of other species (Brook and Alroy 2017, Pimm et al. 2014, Ceballos et al. 2015). In contrast, biodiversity loss is not natural but a global issue and it is not caused by the globalization, but as a result of human activities at the global level (Pimm et al. 2014, Ceballos et al. 2015). Eventually, severe biodiversity losses lead to anthropogenic die-off and extinction of naturally occurring species (Pimm et al. 2014, Ceballos et al. 2015, DeVos et al. 2014). The previous, current and future extinction rates have been estimated using a variety of measures and their estimation methodologies vary (to be between 100 to 10,000 times higher than the natural extinction rate) but they clearly demonstrate that current extinction rates are far above than the \background" rates (Brook and Alroy 2017, Pimm et al. 2014, Ceballos et al. 2015, DeVos et al. 2014, Lamkin and Miller 2016). Aggravatedly, population declines and extirpations are appearing to be more graving than species extinction and negative cascading consequences on ecosystem services (Ceballosa et al. 2020). Substantial information is available on over-exploitation of natural resources by humans in the globalization perspective (Ceballosa et al. 2020, Millennium Ecosystem Assessment, 2005, Groom et al. 2006, Ehrnfeld 2003) and we have lost an estimated US$ 4-20 trillion per year in ecosystem services owing to land-cover change and US$ 6-11 trillion per year from land degradation during 1997 to 2011 (OECD 2019). -

Desertification and Agriculture
BRIEFING Desertification and agriculture SUMMARY Desertification is a land degradation process that occurs in drylands. It affects the land's capacity to supply ecosystem services, such as producing food or hosting biodiversity, to mention the most well-known ones. Its drivers are related to both human activity and the climate, and depend on the specific context. More than 1 billion people in some 100 countries face some level of risk related to the effects of desertification. Climate change can further increase the risk of desertification for those regions of the world that may change into drylands for climatic reasons. Desertification is reversible, but that requires proper indicators to send out alerts about the potential risk of desertification while there is still time and scope for remedial action. However, issues related to the availability and comparability of data across various regions of the world pose big challenges when it comes to measuring and monitoring desertification processes. The United Nations Convention to Combat Desertification and the UN sustainable development goals provide a global framework for assessing desertification. The 2018 World Atlas of Desertification introduced the concept of 'convergence of evidence' to identify areas where multiple pressures cause land change processes relevant to land degradation, of which desertification is a striking example. Desertification involves many environmental and socio-economic aspects. It has many causes and triggers many consequences. A major cause is unsustainable agriculture, a major consequence is the threat to food production. To fully comprehend this two-way relationship requires to understand how agriculture affects land quality, what risks land degradation poses for agricultural production and to what extent a change in agricultural practices can reverse the trend. -

Assessing Climate Change's Contribution to Global Catastrophic
Assessing Climate Change’s Contribution to Global Catastrophic Risk Simon Beard,1,2 Lauren Holt,1 Shahar Avin,1 Asaf Tzachor,1 Luke Kemp,1,3 Seán Ó hÉigeartaigh,1,4 Phil Torres, and Haydn Belfield1 5 A growing number of people and organizations have claimed climate change is an imminent threat to human civilization and survival but there is currently no way to verify such claims. This paper considers what is already known about this risk and describes new ways of assessing it. First, it reviews existing assessments of climate change’s contribution to global catastrophic risk and their limitations. It then introduces new conceptual and evaluative tools, being developed by scholars of global catastrophic risk that could help to overcome these limitations. These connect global catastrophic risk to planetary boundary concepts, classify its key features, and place global catastrophes in a broader policy context. While not yet constituting a comprehensive risk assessment; applying these tools can yield new insights and suggest plausible models of how climate change could cause a global catastrophe. Climate Change; Global Catastrophic Risk; Planetary Boundaries; Food Security; Conflict “Understanding the long-term consequences of nuclear war is not a problem amenable to experimental verification – at least not more than once" Carl Sagan (1983) With these words, Carl Sagan opened one of the most influential papers ever written on the possibility of a global catastrophe. “Nuclear war and climatic catastrophe: Some policy implications” set out a clear and credible mechanism by which nuclear war might lead to human extinction or global civilization collapse by triggering a nuclear winter. -

Swelling Oceans: Planning for Sea Level Rise
Swelling Seas: Planning for sea level rise Westley Owers Bachelor of Town Planning Faculty of the Built Environment University of New South Wales November 2006 Abstract Emissions of greenhouse gases into the atmosphere over the last hundreds of years have placed us in a precarious position, in that we have forced change upon one of the world’s most important systems: climate. This climate change will have devastating impacts around the world. Of all the impacts of human induced climate change, it is sea level rise that is regarded as the most certain. Sea level is expected to rise in a best case scenario of one metre by the year 2100. However, there is still uncertainty surrounding how the environment will react to greenhouse gas emissions, and therefore a sea level rise of up to six metres above current levels by the year 2100 cannot be ruled out. As sea level rises it will bring with it debilitating impacts such as inundation of coastal areas, increased coastal erosion and an increased flooding of inland areas in storm surge occurrences. The scope and magnitude of this environmental issue is such that these impacts will seriously alter human settlement and fragile ecosystems in nations throughout the world. The only way of reducing the impacts of this environmental issue is for government to prepare coastal policy and legislation to address this issue now. The extent at which the impacts of sea level rise are experienced at a local, state and national level within nations will be a direct result of the adaptive response that governments implement to address this environmental issue.
