The climate change is threatening the livelihoods and health of island communities. Small islands are most at risk. They are often uninhabitable due to their small landmass and limited freshwater supplies. These vulnerabilities will increase with sea level rise. Many island nations have made bold attempts to increase their resilience against climate impacts. However, the international community must continue to take action to curb greenhouse gas emissions and prepare for the impacts of changing climate.
The Pacific's small islands face a unique challenge, unlike other regions. The region's dependence on imported material, fuel, food, and fuel is nearly complete. A region's port and airports are particularly vulnerable to storms. Increasing storm surges, saltwater intrusion, and sea level rise have significantly diminished their coping capacity. This makes it more likely that severe flooding will occur and can lead to epidemics.
Many Pacific island communities have started to create climate adaptation plans. Hawaii, for instance, has state agencies that have developed a process for coordination of statewide climate adaption planning. A study on protecting island resources has been funded by the National Oceanic and Atmospheric Administration.
Despite these impressive efforts, the Marshall Islands and Tuvalu are already facing serious challenges. Scientists have predicted that the Marshall Islands may become inhospitable within their lifetimes. Tuvalu is also planning for the loss of its land. Its leaders have been pushing back against big polluters and have recently called upon wealthy countries to live up to their Paris Agreement commitments.
Climate change will also affect freshwater availability and reduce the quantity of potable water for drinking. This will adversely affect the aquifer's recharge, increasing flooding risk and disrupting public sanitation. Furthermore, ecosystems on land will be affected by changes in ocean chemical.
Vanuatu (and Marshall Islands) are particularly at risk due to sea level rise and coastal flooding. They are dependent on limited agricultural resources and are vulnerable to diseases related to warm, humid conditions. In many cases, freshwater supplies on many islands will run dry before the land can be resupplied. People will need to move before the area becomes inhospitable.
Similar challenges will be faced by high-elevation islands. Waimea is an example of such a high-altitude island. It's at more than 2,500ft. It experiences a dry and humid winter but also a warm summer. The island's surface temperature rises to 60 degrees Fahrenheit during these seasons.
Ultimately, island populations will face a crippling water shortage. Insufficient water resources can lead to decreased crop production, reduced freshwater supplies for drinking and an increase in the incidence of disease. These issues will also be affected by the topography and history of governance.
The impact of climate change on migration will have significant practical and economic consequences. Low-island communities such as Vanuatu and Marshall Islands may need to relocate to higher ground to avoid the seas rising.
FAQ
How are extreme weather events related to climate change?
Global warming is directly responsible for extreme weather events such as heat waves and floods, droughts. Cyclones, storms and hurricanes are all a result of global warming. Global warming has caused an increase in atmospheric temperatures. This has had an impact on different weather phenomena worldwide.
Climate scientists claim that the frequency of extreme weather related disasters has more then doubled since 1980. Rising ocean water temperature causes sea levels to go up as well as changing wind patterns. This can affect the distribution of hurricanes and storms in different geographic regions around the globe.
The 2015 El Nino event caused warm water to move towards South America, leading to rising temperatures at alarming rates and heavy rains that caused floods in Peru (and Bolivia) causing property damage and displacement. Many locations, including Antarctica recorded their highest ever temperatures. This shows that there is a clear relationship between global warming trends with the occurrence or frequency extreme weather events.
Another example is Hurricane Irma, which struck in 2017, causing $50 billion in economic damage not only to Florida, but also to other states like Puerto Rico, Cuba, and others. This proves once again that climate change has been responsible for an increase in major storms.
The Intergovernmental Panel on Climate Change, (IPCC), concluded that human activities are increasing severity of climate change. This naturally leads, in turn, to more severe and intense natural disasters globally. Thus, there is strong evidence concerning humans' relationship to extreme weather events occurring around us all.
What can we do to limit or mitigate the impacts of climate change?
There are many measures you can take to mitigate and reduce the impacts of climate change. These include reducing greenhouse gases emissions by using better energy practices and other sources of electricity, improving land management, protecting forests and wild places, protecting against extreme weather, investing in sustainable transport, strengthening early warning system for disasters, starting a research programme on the impact climate change has on biodiversity and ecosystems. Also investing in green technologies like solar cells or wind turbines, encouraging sustainable consume habits, and implementing environmental regulations across all segments of society. Additionally increasing public education about climate change is also important as it encourages people to feel responsible for their actions.
What are the causes and consequences of climate change?
Climate change, which is a global phenomenon, has been driven by an increased amount of greenhouse gases from human activity. The increase was primarily caused by fossil fuel burning to generate electricity and transport. These emissions lead to a greater amount of sun's energy being trapped in Earth’s atmosphere, which results in rising temperatures.
Climate change can also be caused by population growth, land clearing, destruction of ecosystems and energy consumption, over-grazing, and deforestation. This decreases the amount naturally occurring carbon sinks that absorb carbon dioxide from the atmosphere. Climate change may also be caused by natural factors such as changes to solar radiation.
This combination of human activities results in Earth exceeding its ability to balance its energy budget. The result is an average global increase of 1° Celsius since pre-industrial days. Glaciers are melting faster than they become and sea levels are rising as the oceans absorb most of the heat energy. Other negative consequences include water scarcity, droughts and extreme weather events like flooding and hurricanes.
To avoid further damage, it is crucial that we reduce carbon emissions and take steps to curb our emissions. This will give us a fighting chance against climate change's already serious impacts. Reducing our dependence on fossil fuels for electricity production is crucial alongside investing in renewable sources - think wind turbines or solar panels - which do not emit any harmful pollutants into the environment. Reforestation and other sustainable practices can help restore balance to these delicate planetary cycles that we depend on for our survival.
What is climate change and how does it occur?
Climate change refers the long-term shifts that occur in global weather patterns due to an increase in greenhouse gasses in the atmosphere. These gases trap heat, leading to global temperature rises that can result in a range of climate and weather changes. These include rising sea levels and melting glaciers, severe storms and droughts as well as widespread coral reef bleaching and species extinction.
Climate change is caused primarily by human activity. These include burning fossil fuels, transporting electricity, cutting down trees, and farming livestock. These activities cause the atmosphere to heat up much faster than natural processes, like volcanic eruptions. They also emit many times more carbon dioxide than volcanoes.
Deforestation also plays a large role contributing about 15-20% of global greenhouse gas emissions. Trees are destroyed or burned to release their carbon dioxide. Additionally, forests act as a natural carbon sink that removes CO2 from the air; without this absorptive capacity, carbon dioxide levels will continue to rise with devastating consequences for ecosystems around the world.
Human-caused pollution not only releases CO2, but also other harmful gases like methane (CH4) or nitrous oxides (N2O). Industrial processes have used methane extensively and it contributes to significant atmospheric warming. However, N2O is emitted mostly by agricultural soil management activities such as fertilization and tilling. These activities release excessive nitrogen into the soil which leads to N2O production when microbial contact occurs.
The collective efforts of social, economic and political institutions must be made to drastically reduce the emissions and shift away from fossil fuel dependence. A smart approach to reducing atmospheric contamination and preventing CO2 accumulation could be to replace polluting fossil-fuel technologies with ones that encourage zero-waste living. Reforestation projects, which are powerful aid in the fight against climate change by absorbing large quantities of CO2 back into nature and maintaining biodiversity, can help us take responsibility for our environmental impact.
