Graph showing historic temperature change globally and in the Caribbean region. Climate change in the Caribbean poses major risks to the islands in the Caribbean. The main environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. [1]
Sea ice in the Arctic region has declined in recent decades in area and volume due to climate change. It has been melting more in summer than it refreezes in winter. Global warming, caused by greenhouse gas forcing is responsible for the decline in Arctic sea ice. The decline of sea ice in the Arctic has been accelerating during the early ...
Temperature and salinity changes due to global warming and climate change alter the ocean density and lead to changes in vertical stratification. [2] The stratified configuration of the ocean can act as a barrier to water mixing, which impacts the efficiency of vertical exchanges of heat, carbon, oxygen, and other constituents.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
The compounding effects from floods, storm surge, and terrestrial flooding (rivers) are projected to increase due to global warming. [11] There is currently no consensus on how climate change will affect the overall frequency of tropical cyclones. [1] A majority of climate models show a decreased frequency in future projections.

Last year was the warmest year on record, and the first with a global average temperature of more than 1.5 degrees Celsius above the pre-industrial levels. At current rates of warming, 2 degrees ...
Limiting new black carbon deposits in the Arctic could reduce global warming by 0.2 °C by 2050. [142] The effect of decreasing sulfur content of fuel oil for ships since 2020 [143] is estimated to cause an additional 0.05 °C increase in global mean temperature by 2050. [144]
Between 1950 and 2010, São Tomé and Príncipe experienced an increase of 1.5 °C in average annual temperature due to climate change. [67] The country is considered highly vulnerable to its impacts. Climate change is projected to lead to an increased number of warm days and nights, hotter temperatures and increased precipitation. [68]
