Climate change poses a threat to the lives and livelihoods of islands. Small islands are most at risk. They are often uninhabitable, have small land masses, and have limited freshwater resources. These vulnerabilities will increase with sea level rise. A number of island nations have made bold efforts to improve their resilience to climate impacts. But, the international community must continue taking action to reduce greenhouse gas emission and prepare for changing climate impacts.
The Pacific's small islands face a unique challenge, unlike other regions. The region almost completely depends on imports for fuel and food. Ports and airports in the region are susceptible to storms, waves, coastal erosion, and high wave heights. Their resilience has been significantly reduced by increasing storm surges and saltwater intrusion. This makes it more likely that severe flooding will occur and can lead to epidemics.
Many Pacific island communities are now developing climate adaptation plans. Hawaii, for example has developed a system for coordinating state-level climate adaptation planning. Meanwhile, the National Oceanic and Atmospheric Administration (NOAA) has funded a study on island resource safeguarding.
Despite all these efforts, Tuvalu as well as the Marshall Islands face serious problems. 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 hinder freshwater availability for crop irrigation. It will also decrease the availability of potable waters for drinking. This will adversely impact the aquifer replenishment, leading to increased flooding and disruptions in public sanitation. Aside from the ocean chemistry changes, these will have an effect on the ecosystems at land.
Vanuatu (and Marshall Islands) are particularly at risk due to sea level rise and coastal flooding. Their agricultural resources are limited and they are more susceptible to the diseases that come with humid, warm weather. Their freshwater resources will be depleted on many islands before they can replenish them. The result is that people will have to leave the area before it becomes uninhabitable.
High-elevation islands will also face similar challenges. Waimea, for instance, is at an elevation of over 2,500 feet. It has a dry, hot winter and a pleasant summer. The island's average surface temperature is 60 degrees Fahrenheit in these seasons.
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 and Marshall Islands, which are low-island communities, may have to relocate to higher ground as the seas rise.

What does climate change mean for the oceans and marine life of the world?
What is the effect of climate change upon the world's oceans?
Since its inception, climate changes have had significant impacts on the oceans of the world and the marine life that surrounds them. The loss of the ozone coating and constant oceanic temperature increase causes significant disruptions in marine ecosystems.
Unpredictable weather conditions and stronger storms are also linked to climate change, leading to extreme surges in sea levels that can prove deadly for coastal areas. Temperature changes can also cause water levels to drop, causing "dead zones", areas where there is less marine life.
Ocean acidification is also a result of excess carbon dioxide that has built up in the oceans. This is due to climate change. Ocean acidification raises the pH balance which disrupts essential functions of animals unable to adapt such as oysters, clams, and crabs as their shells become weakened.
Higher temperatures can also cause changes in natural habitats. They may shrink or change their geographical location, making it unhabitable for species that depend on them. This increase in ocean stress accelerates already high extinction rates amongst many species worldwide causing a severe imbalance between predators and prey that might eventually lead to complete extinctions.
Climate change has ripple effects on entire ecosystems, affecting multiple species directly and indirectly. Evaporation, lowering water volumes, or temperature shifts can all impact sustainable development of fisheries and other maritime activities. The effects of climate change continue to impact the lives of entire species on this planet.
What are the impacts of climate change on society and the environment?
The environment and society are both affected by climate change. Climate change will have many impacts on the environment. These changes can have grave consequences for human population, increasing instability and inflicting insect-borne disease and poverty on a large scale, as well as altering migration patterns and destroying important habitats.
Already, climate change has had a broad range of devastating effects on society and the environment around the globe. This is expected to get worse as global temperatures continue rising.
Ocean levels rising due to melting ice caps is one of the most pervasive effects of climate change worldwide. This causes shoreline erosion along many coastlines and increases the risk of flooding for coastal communities. Saltwater intrusion is also a problem, and can negatively impact freshwater supplies along the coasts of many countries.
Many countries are experiencing extreme weather events, such as droughts or heatwaves as a result climate change. These events cause mass destruction to homes and businesses, leading to displacement or relocation of communities or wiping out whole towns in some cases. Extreme storms can also cause flooding and landslides, which increase the damage to infrastructure like roads and railways.
Additionally, wildfires caused climate change are more common than ever. They can be devastating for both the habitats and the people who live nearby.
These drastic changes often lead to displacement or refugee crises. People move out of their homes involuntarily or voluntarily when their communities become unsafe or uninhabitable due to the altered climate.
Increased aridity also increases dust storms worldwide with unhealthy air pollution caused by these making it difficult for people who suffer from respiratory illnesses such as asthma especially vulnerable. The possibility of pest infestations increasing is linked to increased temperature extremes, a phenomenon known "greenhouse bug". This further impacts global food insecurity. A smaller number of crops with lower nutritional quality could lead to additional hardships for those already struggling to make ends met.
