The most dire climate change scenario could be like this. We must take steps to prevent it.


Sometimes, you must face the possibility of the worst result in order to avoid it.

The raging wildfires as well as Atomic Tangerine skies which have recently affected westwestern US are yet another instance of the effects on changes in the weather. They could be just a prelude to other worrying developments in the near future.

Experts trying to determine the degree of climate change that are likely to occur in 2100 are referring to the most severe scenario being “RCP 8.5.” There are many variations of “Representative Concentration Pathways” starting with the scenario that is the most likely to be successful RCP 1.9 in which warming over levels pre-industrial is contained to approximately 1.5degC along with dramatic declines in emissions.


The World Economic Forum has used data from the Climate Impact Lab, Climate Central and Climate Central, the Washington Post, and NASA satellites to develop a graphicof the worst-case scenario to help demonstrate the impacts that are expected to occur.

Below is an example of the most likely scenario of temperatures around the globe to the end of the century. Average temperatures from June to August are shown as a dark blue that is equal to zero degrees Celsius (32degF) or below which gets warmer in mild blue and green orange, yellow and a dark red that is equal with 38 degC (100.4degF) as well as above.


Phoenix, Arizona is already popular for its hot temperatures. The city was sweltering hot last month. is home to an increasing populace of 1.7 million dependent in air conditioning set an old record of 46 years by having eight days of summer with temperatures that reached at least 115 degrees Fahrenheit (46.1degC).

Conditions may get even more uncomfortable for America’s hottest city. In the worst-case scenario , as shown in the of the excerpt below, the number of consecutive days for Phoenix every year with temperatures of 32 degrees could be 200 by 2100, compared to an average of only 158 days in the 20th century.


On the other hand of the US, Florida is faced by rising temperatures and increasing sea levels. In the below excerpt, we can see the projections for completely loss of Florida coastline in the event that temperatures rise by 4 degrees Celsius over preindustrial levels.

Seawalls and levees may be constructed to safeguard a large portion of the coastline in Florida, certain communities have found the expense for the project to be excessive. Based on one estimation that it could cost Florida around $76 billion – which is equivalent to the majority of the state’s year-end budget for building the seawalls that are needed to hold against rising sea levels until 2040.


South Asia would be hit very hard in the worst-case climate scenario and the most vulnerable populations in the region will likely take the brunt of the burden. The most extreme scenario will see those seeking refuge from the negative effects of climate change accounting for almost a quarter of all refugees from the region in 2050.

The dark red color in the below excerpt is a representation of the average temperature from June to August, which is 38 degrees Celsius (100.4degF) and higher. New Delhi, a city that has a population of around 22 million in which air conditioning is responsible for over half of the electrical use during summer can increase from six months per year , averaging 32 degrees Celsius as of 1960. This could increase to eight months in 2100.


It is believed that the ASEAN Region is expected to be a major target in the event of a catastrophic scenario. In the below excerpt the orange color represents the average temperature from June to August that are higher than 30 degrees Celsius (86degF). This region is already among the regions most susceptible to extreme weather conditions and rising sea levels that are associated with global warming.

For Viet Nam, significant portions of the country are predicted to be submerged in 2050 by the rising levels of seawater. Meanwhile, in Bangladesh over 13 million people are likely to be relocated due to the diverse impacts of climate change the same time.


Europe which is home to at most 22 million of farmers as well as employees have been vulnerable to extreme weather conditions is also expected to witness dramatic changes within the next two decades If this worst-case scenario for climate change unfolds.

In the following excerpt in the excerpt below, we can observe an average temperature range from June to August in the south of Spain, Italy and Greece with temperatures of around 30degC (86degF). Alongside warming, climate change could alter the patterns of precipitation. In London the maximum annual temperatures could be up to 4 degrees Celsius hotter in the 2070s on average and the city might be experiencing an increase of 52 millimetres annually in rainfall.


It’s a grim outlook, but the worst consequences from climate changes are avoidable by ensuring that major polluting nations take action to implement effective climate policy. Also, we can limit warming by restraining attempts to undermine scientific evidence, and removing carbon dioxide from the atmosphere , or compensating it with the planting of new forests and enhancing the energy and transportation infrastructures.
