Natural climate solutions.The way forward

Climate change is a global challenge that threatens global ecological security and sustainable development.Find-ing ways to mitigate their impacts is paramount through engineering carbon storage,low-carbon energy tran-sition,or natural climate solutions(NCS).NCS involve a set of measures(e.g.,afforestation,land restoration,biochar reuse or sustainable land use practices).Implementing NCS increases carbon sequestration and mitigates climate change at the lowest costs and greenest ways.In addition,NCS practices can improve multiple ecosystem services(ES)such as air quality,flood and erosion regulation,pest control,water purification,wild food biomass,recreation or landscape aesthetics.However,unsustainable implementation of NCS,such as over-afforestation of dense mono-forest,can lead to tradeoffs with water supply,wildfire risk,and decreased grasslands and crop-lands.Therefore,to optimise the NCS implementation,reducing the tradeoffs associated and transforming the“expand ecosystem area”to“improve ecosystem management efficiency”is vital.Although NCS can contribute significantly to mitigating climate change,systematic climate actions must be accompanied by a transformation in the global society and investment in new technologies.This will be key to addressing global challenges such as the achievement of Sustainable Development Goals(SDGs),such as SDG 13(Climate Action),SDG 15(Life on Land),SDG 2(Zero Hunger),SDG 3(Good Health and Wellbeing),SDG 6(Clean Water and Sanitation),and SDG 14(Life Bellow Water).

Environmental and Climate Justice in Palestine

To have a clean, safe, and functional environment is not only essential for the purpose of preservation, but also imperative for safeguarding the most fundamental of human rights. Resolution 45/94 of the United Nations (UN) General Assembly also stresses and acknowledges that: “all individuals are entitled to live in an environment adequate for their health and wellbeing” (United Nations Digital Library System, 1991). Environmental and climate justice, which: “emerged in the context of the local environmental struggles of directly oppressed groups”, is a global movement dedicated to ensuring equal protection of people’s human rights (i.e., water, health, life, etc.) in the face of the climate crisis. Moreover, health, environment and human rights are part of the 2030 agenda (in particular, SDG 1, SDG 5, SDG 6, SDG 7, SDG 13, SDG 16, SDG 17). Individually, both environmental and climate justice are rooted in an intersectional outlook, by which they highlight the common threads between communities and the people’s inclusion, irrespective of race, class, or gender, in the pursuit of justice. On the other hand, they recognise and acknowledge the role and consequences of climate change in economic, social, and political dimensions;thus, drawing emphasis on the rights of people under the emerging inequities. In the case of Palestine, the Palestinian community is increasingly becoming vulnerable to these effects and the resulting inequalities of climate change. This vulnerability stems from: 1) The right to life;clean WASH;equitable work opportunities;access to resources;and free movement;are all examples of human rights that the Israeli colonial regime infringes upon;2) Infrastructure is essential for climate adaptation: 61% of the West Bank is ultimately barred from building infrastructure (B’Tselem, 2019) and Gaza Strip has major gaps in infrastructure due to intentional destruction by Israel;3) Palestinian deprivation of the sovereign right to natural resources by Israel;4) Apartheid system in water accessibility: Israeli water usage per person is over three times higher than that of Palestinians (their usage is under the WHO recommended minimum per day) (B’Tselem, 2023);and 5) Violent settler attacks. In 2022 alone, the Applied Research Institute-Jerusalem (ARIJ) recorded 1527 settler attacks that targeted land, properties, livestock, agriculture and even Palestinian civilians. The ongoing neglect of these concerns and the persistent colonization of Palestine by Israel unequivocally and unwaveringly affect the human rights of Palestinians. The power dynamics at play especially hamper the Palestinian ability to exercise and fulfill their inalienable human rights and to tackle the obstacles to justice in their environment.

Asymptotic Solutions to a Nonlinear Climate Oscillation Model

A class of nonlinear global climate oscillation models is considered. Using perturbation theory and its methods, solutions to the asymptotic expansions of some related problems are constructed. These asymptotic expansions of the solutions for the original problem possess a higher approximation. The perturbed asymptotic method is an analyti cmethod.

Improving Forest Soil Health and Ecosystem Services to Minimize the Impact of Climate Change

The presence of increasing quantities of greenhouse gases is fostering climate change. This review chronicles the emerging research addressing the role of soil to sequester carbon across biomes, understand the soil mechanisms responsible for soil carbon preservation and indicate the need to estimate the intensity for site-specific carbon sequestration. To negate the continuing increase of atmospheric greenhouse gases requires using well-documented soil pathways to sequester carbon. For deciduous forests, emerging concepts center around two approaches: 1) increasing the ecosystem’s net primary productivity coupled with increasing the carbon supply into soil using appropriate land management practices, and 2) supporting soil processes that increase soil carbon retention. New perspectives suggest that soil carbon may be preferentially preserved because organic materials are adsorbed onto phyllosilicates and oxyhydroxides and subsequently protected from microbial degradation because of soil structure improvement. Thus, augmenting soil structure may promote soil organic matter persistence. Each soil has a soil carbon carrying capacity;however, soil survey databases infer that soil organic matter concentrations have a significant variance at the soil series level. The need exists for more precise estimates of the soil’s carbon carrying capacity at the pedon level to support land management practices that encourage land management options designed to preserve soil carbon. However, the complexity of the soil system may limit its usefulness for routine soil management decisions. Our modern understanding of soil carbon preservation processes and emerging soil carbon saturation deficit concepts may potentially improve decision support tools for managing soils for carbon sequestration.

Global Effect of Climate Change on Seasonal Cycles,Vector Population and Rising Challenges of Communicable Diseases:A Review

This article explains ongoing changes in global climate and their effect on the resurgence of vector and pathogen populations in various parts of the world.Today,major prevailing changes are the elevation of global temperature and accidental torrent rains,floods,droughts,and loss of productivity and food commodities.Due to the increase in water surface area and the longer presence of flood water,the breeding of insect vectors becomes very high;it is responsible for the emergence and re-emergence of so many communicable diseases.Due to the development of resistance to chemicals in insect pests,and pathogens and lack of control measures,communicable zoonotic diseases are remerging with high infectivity and mortality.This condition is becoming more alarming as the climate is favoring pathogen-host interactions and vector populations.Rapid changes seen in meteorology are promoting an unmanageable array of vector-borne infectious diseases,such as malaria,Japanese encephalitis,filarial,dengue,and leishmaniasis.Similarly,due to unhygienic conditions,poor sanitation,and infected ground and surface water outbreak of enteric infections such as cholera,vibriosis,and rotavirus is seen on the rise.In addition,parasitic infection ascariasis,fasciolosis,schistosomiasis,and dysentery cases are increasing.Today climate change is a major issue and challenge that needs timely quick solutions.Climate change is imposing non-adaptive forced human migration territorial conflicts,decreasing ecosystem productivity,disease outbreaks,and impelling unequal resource utilization.Rapid climate changes,parasites,pathogens,and vector populations are on the rise,which is making great threats to global health and the environment.This article highlighted the necessity to develop new strategies and control measures to cut down rising vector and pathogen populations in endemic areas.For finding quick solutions educational awareness,technology up-gradation,new vaccines,and safety measures have to be adopted to break the cycle of dreadful communicable diseases shortly.

Synergistic integration of climate change and zoonotic diseases by artificial intelligence:a holistic approach for sustainable solutions

Artificial intelligence(AI)is a rapidly evolving field that can impel research in communicable diseases with respect to climate projections,ecological indicators and environmental impact,at the same time revealing new,previously overlooked events.A number of zoonotic and vector-borne diseases already show signs of expanding their northern geographical ranges and appropriate risk assessment and decision support are urgently needed.The deployment of AI-enabled monitoring systems tracking animal populations and environmental changes is of immense potential in the study of transmission under different climate scenarios.In addition,AI's capability to identify new treatments should not only accelerate drug and vaccine discovery but also help predicting their effectiveness,while its contribution to genetic pathogen speciation would assist the evaluation of spillover risks with regard to viral infections from animals to human.Close collaboration between AI experts,epidemiologists and other stakeholders is not only crucial for responding to challenges interconnected with a variety of variables effectively,but also necessary to warrant responsible AI use.Despite its wider successful implementation in many fields,AI should be seen as a complement to,rather than a replacement of,traditional public health measures.

Markers for Global Climate Change and Its Impact on Social, Biological and Ecological Systems: A Review

Present article sketches out major climate induced changes in marine, aquatic and terrestrial life. Few important biomarkers such as ecological, meteorological, socioeconomic, thermal, biophysical and biological, behavioral markers of climate change and global environmental stress have been highlighted to predict the future challenges and finding appropriate solutions. Though, so many climate change induced effects are visible but few unpredictable effects may be seen in future. Therefore, all such effects have been acknowledged, and tried to find appropriate solutions. Most visible effect is collection of high amounts of carbon dioxide in the atmosphere which is responsible for green house effect and causing natural calamities round the globe. It is not only jeopardized the survival of terrestrial, fresh water animals mainly planktons, bottom dwellers;coral reefs, algae, fish fauna in marine environment belong to different taxon but also responsible for disruption of ocean’s food web due to non-assimilation of extra carbon dioxide by the ocean water. There is a sharp decline in fresh water and sea shore micro-flora and micro-fauna. Other major visible effects are loss of biodiversity, depletion of forests, land degradation, severe floods and draughts. On other hand sudden changes in weather conditions causing irreparable devastations due to hurricanes and typhoons, storms, lightening, earthquakes and tsunamis are normally on rise. Both economic and ecological breakdowns are occurring more frequently which are more impactful and persistent. Climate change is major human health stressor;it is making fragmentation of socio-cultural bonds and reducing fertility of soil finally crop production. Climate change is imposing non-adaptive forced human migration, territorial conflicts, decreasing ecosystem productivity, disease out breaks, and impelling unequal resource utilization.

Market-based solutions:An appropriate approach to resolve environmental problems

It was the first time that the Intergovernmental Panel on Climate Change(IPCC),which was founded in 1988,regarded climate change as a significant international political problem(O'Brien and Williams 2007).Over the next decades,environmentalist and policy makers have been applying many efficient ways to solve various environmental problems and have gained achievements.With the support of successful cases,this paper will focus on the market-based solutions and discuss its advantages compared with the conventional approach.

Raising the Stake of Global Warming and Climate Change in Nigeria Media： Implications for Development

The elements that mid-wife news and editorial contents remain： what, who, where, when, why, and how, typical of Lasswell＇s （1948） conceptual model of communication. The operational actualization of this in theory and practice exemplifies a paradigm of news and other editorial contents reporting slant that pays more attention to dramatizing events and incidents, at best exacerbating, psychologically, panic, apprehension, and tension, but hardly focusing on solution to critical situation in society. However, journalism may not always be about the curses; it could be about cures, particularly in regard to climate change/global warming issues in developing economies like Africa＇s. Hence, the thrust of this paper is a strong advocacy for curative journalism that should issue from a well fed body of science-based information on how to adapt to the menace of global warming palaver in developing nations of the world, especially Nigeria. It advances that new media scientific journalism that could benefit society should do more of probing solution rather than concentrate on the throes： the former acting as an anti-depressant journalism instead of a hopeless journalism.

How Should Mine Reclamation Design Effectively Respond to Climate Change? A Mini Review Opinion

Climate change is a growing concern with each of the last three decades being successively warmer than preceding decades. Mine wastes are mandatory required to be reclaimed after mine operation due to their high risks of contaminating environment and huge volumes occupying large useable land resources. However, most traditional mine reclamation plans are designed with an assumption of unchanged, consistent conditions of environment, climate and hydrology conditions, which may not work properly under the global climate change. This paper discussed the previously ignored problem that is how mine reclamation design should effectively respond to climate change. Through reviewing the current responding strategy to the climate change during mine reclamation and closure, this mini review was structured, and the opinion is concluded that the more active the designers consider the factors of climate change, the more manageable, predictable and sustainable the reclaimed ecosystem and landscape are. Nature-based solutions can act as the general guidelines when considering climate change with mine reclamation, and the six-step framework aims more specifically on mine reclamation. The two methods can work together to help designers and regulators to effectively respond to climate change when planning mine reclamation and closure.

国内外提升生态碳汇贡献的经验比较

生态碳汇是实现“双碳”目标不可或缺且具有成本优势的碳移除手段,其在全球气候治理中的作用逐渐受到各国政府的重视,各国相继出台相关支持政策。本文对中国和美国、日本、新西兰、欧盟等发达国家和地区的碳汇政策进行了梳理和对比,发现提升生态碳汇能力和贡献的措施包括保护、管理和恢复生态系统等供给端措施,以及扩大对木质林产品需求等需求端措施。欧美日新等发达国家侧重于成本分担的管理恢复措施和需求端措施,而中国侧重于以中央投资的大规模生态工程为主的保护和恢复措施,在管理和需求端措施方面有较大的增汇潜力。此外,中国碳市场中的生态碳汇项目虽然在开发形式上处于世界领先水平,但也面临方法学有待改进、开发成本高风险大、政策支持不足等挑战。本文提出了提升中国生态碳汇贡献的政策建议,包括扩大增汇路径、加大对管理和需求端措施的政策支持力度以及完善生态碳汇项目的方法学和核算方法等。

A Plan to Extract Gigatons of Atmospheric CO2 through Agroforestry

The UN International Panel Environment Programme (“UNEP”), 2023 Emissions Gap Report urgently presses the global community to adopt a two-pronged approach to reduce atmospheric concentration of CO2—expedite efforts to reduce annual CO2 emissions;and increase investment in large-scale carbon dioxide removal (“CDR”) projects. The Gap Report sets a 2050 target of six-gigatons annual land-based CDR. Our proposed agroforestry project will convert thirty-five-million acres of rangeland in the American Great Plains to silvopasture, combining growing trees and raising livestock. Employing agroforestry interests 61% of Great Plaints farmers/ranchers recently surveyed. The Project plans to annually collect + six-gigatons CO2 equiv. of fallen leaves and store the stable carbon-rich biomass underground for centuries. The purpose of this paper is to describe the framework for formation of a global partnership at the local, regional, and international levels to coordinate public and private financing mechanisms, implement, and operate a large-scale CDR Project that will meaningfully impact the global effort to mitigate climate change.

Approximate Solution for Mechanism of Thermally and Wind-driven Ocean Circulation

The thermally and wind-driven ocean circulation is a complicated natural phenomenon in the atmospheric physics. Hence we need to reduce it using basic models and solve the models using approximate methods. A non-linear model of the thermally and wind-driven ocean circulation is used in this paper. The results show that the zero solution of the linear equation is a stable focus point, which is the path curve trend origin point as time (t) trend to infinity. By using the homotopic mapping perturbation method, the exact solution of the model is obtained. The homotopic mapping perturbation method is an analytic solving method, so the obtained solution can be used for analytic operating sequentially. And then we can also obtain the diversified qualitative and quantitative behaviors for corresponding physical quantities.

Stability of weak solutions to climate dynamics model with effects of topography and non-constant external force

In this paper, a climate dynamics model with the effects of topography and a non-constant external force, which consists of the Navier-Stokes equations and a temperature equation arising from the evolution process of the atmosphere, was considered.Under certain assumptions imposed on the initial data and by using some delicate estimates and compactness arguments, we proved the L^1-stability of weak solutions to the atmospheric equations.

Detection of the Hazards That Threaten Some Coastal Areas, and Ecosystem-Based Solution to Strengthen the Natural Defenses

The coastal strip of the Nile delta has been vulnerable to environmental hazards. Field surveys, interpretation of Landsat enhanced thematic mapper imageries (ETM), and hydrochemistry analysis of the water samples was used as methods and materials to detect the hazards associated with climate change which threaten some natural protection coastal areas of the central part of the Nile Delta and assess its magnitude. The invasion of seawaters is the main hazard due to the impacts of global warming phenomena. Elimination of the coastal dunes which act as natural defenses has been accelerating the negative impacts that have been appearing clearly on low-lying lands. Planting that protected areas of the coastal strip are considered the most suitable ecosystem-based and most beneficial solution should be authorized and adopted by the local administration to preserve those areas and adapt to these disasters.

Fast action on short-lived climate pollutants and nature-based solutions to help countries meet carbon neutrality goals

Scientific studies show that fast actions to reduce near-term warming are essential to slowing self-reinforcing climate feedbacks and avoiding irreversible tipping points.Yet cutting CO_(2) emissions only marginally impacts near-term warming,This study identifies two of the most ffective mitigation strategies to limit near-term warming beyond CO_(2) mitigation,namely reducing short-lived climate pollutants(SLCPs)and promoting targeted nature-based solutions(NbS),and comprehensively reviews the latest scientifie progress in these fields.Studies show that quickly reducing SLCP emissions,particularly hydrofuorocarbons(HFCs),methane,and black carbon,from ll relevant sectors can avoid up to 0.6℃ of warming by 2050.Additionally,promoting targeted NbS that protect and enhance natural carbon sinks ncluding in forests,wetlands,grasslands,and agricultural lands,can avoid emssions of 23.8 Gt of CO_(2)e per year in 2030,without jeopardizing food security and biodiversity.Based on the scientific evidence,we provided a series of policy recommendations on SLCPs and NbS,including:1)implementing the Kigali Amendment to reduce HFC emissions;2)deploying cost-effective,sector-based measures to reduce methane and black carbon emissions;and 3)implementing targeted NbS to protect and enhance existing carbon sinks and shifting away from forest-burning bioenergy.These fast-acting strategies on SLCPs and NbS will play a key role in securing the most avoided warming in the near-term and help countries meet their mid-century carbon neutrality goals.Finally,we proposed future research topics,including:improving measurement and monitoring systems and techniques for SLCP emissions;developing and improving assessments of marginal abatement costs for SLCP mitigation in dfferent sectors;better quantifying the avoided warming potential from protecting dfferent types of natural carbon sinks by 2030,2050,and over longer periods;and identifying whether there are any biomass types for energy sources that are consistent with the United Nations Environment Assembly's 2022 resolution adopting a definition of NbS.Further research in these areas could help address barriers to adoption and assist countries with better integrating the most effective SLCP and NbS strategies into their climate policies.
