The health and livelihoods on islands are at risk from climate change. Particularly vulnerable are small islands. They are often inhospitable, have small land masses and are limited in freshwater resources. These vulnerabilities are likely to increase with the sea level rising. A number of islands have made bold efforts in improving their climate resilience. The international community must keep up the pressure on greenhouse gas emissions to limit them and prepare for climate change.
The Pacific's small islands face a unique challenge, unlike other regions. The region is almost entirely dependent on imported material, fuel, and food. A region's port and airports are particularly vulnerable to storms. They are now less able to cope with increasing storm surges, saltwater intrusion and sea level rising. This increases the risk of severe flooding, and even disease outbreaks.
Many Pacific island communities are now developing climate adaptation plans. Hawaii, for example. State agencies have developed a process that coordinates statewide adaptation planning. A study on protecting island resources has been funded by the National Oceanic and Atmospheric Administration.
Despite these remarkable efforts, Tuvalu is already facing serious difficulties. Scientists predict that the Marshall Islands will soon be uninhabitable. Tuvalu, in the same way, has started planning to disappear all its land. Its leaders are defending big polluters, and recently called on wealthy countries to honor their Paris Agreement obligations.
Climate change will also affect freshwater availability and reduce the quantity of potable water for drinking. This will adversely impact the aquifer replenishment, leading to increased flooding and disruptions in public sanitation. Furthermore, ecosystems on land will be affected by changes in ocean chemical.
Vanuatu's low-lying islands and Marshall Islands will be most at risk of coastal flooding and sea rise. They are dependent on limited agricultural resources and are vulnerable to diseases related to warm, humid conditions. On many islands, their freshwater supplies will run out before the land can be replenished. People will need to migrate to avoid the area becoming uninhabitable.
High-elevation isles will also have to face similar challenges. Waimea, for example, is located at a high elevation of more than 2,500 feet. It experiences a dry and humid winter but also a warm summer. The island's temperature at the surface is often above 60 degrees Fahrenheit.
In the long-term, island communities will be faced with a water shortage that is severe. Insufficient water resources can lead to decreased crop production, reduced freshwater supplies for drinking and an increase in the incidence of disease. Other factors that will play a role in these issues include the topography of the islands and the history of governance.
Migratory impacts of climate change are likely to present both economic and practical problems. Vanuatu's low-island community of Marshall Islands might have to move up before the seas submerge.

What is the contribution of human activity to climate change?
Climate change is caused primarily by human activity. According to the Intergovernmental Panel on Climate Change, humans have contributed more than 70% of global warming since mid-20th century.
Carbon dioxide is released into the atmosphere by burning fossil fuels like oil, coal, and gas. This increases the already high levels of atmospheric CO2, which acts as a greenhouse gas by trapping heat from Earth's sun and increasing temperatures. This causes higher ocean levels, as Arctic ice melts. It also scrambles weather patterns across the globe, leading to dangerous storms, droughts, floods and other problems that can affect food production and human health.
Deforestation: Trees that sequester atmospheric CO2 in their trunks during photosynthesis are destroyed by deforestation. Deforestation also raises albedo (the amount of reflected solar radiation that is returned into space) and reduces solar heat absorption by earth's surface, thereby promoting global warming. It also reduces the quality of local air, with deforestation being permanently linked to respiratory problems.
Farming: Each year, between 14% and 18% global anthropogenic greenhouse gases are released by the animal agriculture industry. Animal waste releases large amounts of methane gas into the atmosphere due to its composition rich in methane bacteria Eating less or no animal products altogether can be an effective way to reduce your contribution towards global warming from this source alone., Agriculture itself also relies heavily on fertilizers which contain nitrous oxide released into our atmosphere directly harms humans creating smog from ground level ozone harming our respiratory system making polluted air hazardous for life.
In conclusion, human activity has been drastically impacting our environment for centuries now, but with rapid advances made in technology such as renewable energy sources availability we have started turning our heads towards the future leaving behind carbon-emitting heavy industries results will soon start speaking themselves clearly when we leverage on technology through green innovation paving away toward eco-friendly efforts combatting climate change efficiently keeping everyone safe under prosperous nature purview.
What are the causes for climate change
Climate change is a global phenomenon. It has been caused by an increase in greenhouse gases that are emitted from humans. These emissions trap more sun's heat, causing global temperature rises.
Climate change can also be caused by population growth, land clearing, destruction of ecosystems and energy consumption, over-grazing, and deforestation. This reduces the amount of carbon sinks naturally found in the atmosphere that absorb CO2. Climate change can also be caused by natural forces like changes in solar radiation.
These human activities combined result in Earth being unable to adequately balance its energy resources, which has led to an average global temperature increase of 1 degree Celsius from pre-industrial times. Glaciers melt faster than they form and sea levels rise as oceans absorb most of this heat energy. Other damaging consequences include water scarcity and droughts or extreme weather events like floods and hurricanes caused by frequent heavy precipitation on saturated soils.
It is vital that we reduce our carbon footprint immediately and stop releasing greenhouse gases. This will help us protect ourselves against further damage from climate change. It is vital to reduce our dependency on fossil fuels for electricity production. Additionally, invest in renewable resources such as solar panels or wind turbines. These sources are not harmful to the environment. These delicate planetary cycles are also susceptible to other sustainable practices, like reforestation.
What role do greenhouse gases play in climate change?
Climate change is driven by greenhouse gases. They act like an invisible blanket around the Earth, trapping infrared radiation and warming the atmosphere. Without them the planet would be much more colder than it currently is.
Human activity can cause greenhouse gases, such as the burning of fossil fuels and other industries that emit emissions. As more heat enters the atmosphere from these activities, it leads to increased temperatures and extreme weather.
Carbon dioxide (CO2), the most potent greenhouse gas, is released by fossil fuels like gas, oil, and coal. Methane (CH4), nitrous oxide (N2O), and fluorinated gases (F-gases) are also major contributors to climate change.
Since preindustrial times, the concentration of greenhouse gases has risen significantly due to human activity. Global warming has caused an increase in temperature all around the globe, and in our oceans. It is also leading to changes such as intense storms and droughts; melting glaciers; and rising seas.
To reduce further damage caused by climate change, human beings need to decrease their greenhouse gas emissions. We can do this by shifting away from fossil fuels in favor of renewable energy sources like solar and wind power. We can also take measures such as reforestation or adopting agricultural methods that allow the soil to absorb more CO2 from the air. These activities will lower the atmospheric concentrations of greenhouse gasses and make the Earth a more healthy place for all life.
What impact does politics have on global efforts to tackle climate change?
Climate change is a highly politicized issue that has created a great deal of division among nations, governments, and individuals. The political stances taken by different actors will impact the implementation measures to combat climate changes. It has been difficult for global consensus to address this urgent environment crisis.
Most scientists agree that humans are causing climate change. This is why it is urgent to act. The politics surrounding these issues often undermines global cooperation which is needed to make effective progress in implementing sustainable energy practices, upholding regulations protecting natural habitats, researching viable technological solutions, and other climate change interventions.
Many governments around the globe want to protect business interests and enforce policies that restrict business activities. This often clashes with regulations that experts recommend for effectively addressing climate change. Without strong commitments of all participating countries, and international action on a large scale, it becomes difficult for any state or group or states to effectively address climate-change legislation.
Differences in power dynamics among countries further complicate gaining full consensus on how best to tackle climate change. Countries with more economic power frequently appoint their own representatives for international negotiations over the environment. This can lead lopsided discussions between countries' perceived interests and those of all other parties. In addition, potential side effects from implementing radical changes such as geoengineering have been debated heavily at both national and international levels.
In the same way, grassroots movements are fighting powerful opponents at the grassroots level. These include corporate ownerships and well-funded lobbyists looking to retain politically favorable positions.
Properly distributing resources allocated towards any intervention program while being mindful of political divisions between nations will be critical if any coordinated effort aimed at mitigating our current environmental crisis is going successfully to come to fruition.
