Impact of Global Warming!

Global warming not only involves an increase in temperature, it also leads to a host of other environmental problems. You sure you want to stay complacent about it?

The impact of global warming is slowly emerging, such include the rise in sea-level, the occurrence of extreme weather events, as well as changes to ecological systems.

Temperature increase, along with sea-ice melting, have lead to substantial sea-level rise since the year 1880. Consequently, many low lying areas may become submerged under water, causing residents to lose their homes.  In the Mediterranean areas, many of the world heritage sites as designated by UNESCO, such as Venice and the Italian city of Pisa, now faces the risk of damage due to sea-level rise.

Global Warming will also increase the frequency and intensity of extreme weather events. Over the past year, extreme weather events have occured in various parts of the world. Extreme weather events can leads to flight cancellation, suspension of work and education, infrastructural damage, economic losses and even injuries and deaths.

Changes in climate and the environment not only affect human, it also disturbs the biological cycles of species, hence, will affect ecological systems and the entire food chain. According to a research published on the Proceedings of the National Academy of Sciences of the United States of America, 88 species are impacted by Phenological Synchrony. As a result of increasing temperature, 99% of newborn green sea turtles in Australia are now a female. A report from IPCC has stated that if the global average temperature is increased for 2℃, all of the world's coral will go into extinction.

Heat wave sweeps Europe early with killer high temperatures

As global warming worsens, a heat wave earlier this year slammed Europe, reaching 46 degrees Celsius in Spain. According to the World Meteorological Organization (WMO), temperatures in Spain and some regions of France are 10 degrees higher than average for the same time period. The severe weather conditions are not only killing people, but also destroying our ecosystem. According to the BBC, at least 1,000 people have died in Spain and Portugal in recent days due to high temperatures, and the high and dry temperatures have led to wildfires, which have devastated the ecosystem.

Deadly hot weather: the apparent temperature is approaching 40 ° C

The Hong Kong Observatory recorded a temperature of 36.1° C on July 24, breaking the record of 35.7 ° C set in 1968 and the highest July temperature recorded in Hong Kong since 1884. Furthermore, it even reached 40°C in certain areas of Hong Kong. The term "apparent temperature" relates to how the body perceives air temperature, which is typically influenced by relative humidity, wind speed, and air temperature. Since skin sensation is the primary mechanism by which humans perceive their body temperatures, the apparent temperature rises under direct sunshine. The environment makes the body feel hotter when the sensory temperature is higher than the air temperature. As the world warms further, we will experience warmer climates than the actual temperature.

Up to 5.7° C of global warming may occur by 2100

The United Nations Intergovernmental Panel on Climate Change (IPCC) reported in its Sixth Assessment Report (AR6) that greenhouse gas emissions from human activities have already warmed the planet's surface by 1.07°C and are predicted to surpass the 1.5°C warming barrier in 2040. Global glaciers are retreating, Arctic Sea ice is shrinking, sea levels are rising more quickly, and marine heat waves are happening more frequently as a result of rising global temperatures. The monsoon season is intensifying dramatically in East Asia as a result of greenhouse gas emissions, and it will likely continue to accelerate globally. While global warming is predicted to reach 3.2°C by 2100 and, in the worst case, even reach 5.7°C if greenhouse gas emissions are not reduced.

New polar bear population emerge in the face of global warming

Sea ice is melting quickly and shrinking in size as a result of global warming. As the time it takes to form sea ice shortens, so does the time the polar bears spend foraging. Recently, researchers have discovered a new population of polar bears in southeast Greenland. The new polar bear population will hunt not only on sea ice, but also on smaller areas of freshwater ice in glaciers when sea ice is unavailable, greatly improving their chances of survival in extreme climates. The emergence of these Greenlandic polar bears indicates that the species will adapt to climate change by evolving new feeding patterns.
