Climate change does no respect the border; it does not respect who are rich and poor, small and big. Therefore, that is what we call “global challenges” which require solidarity.
Definition of climate change:
The United Nation Framework Convention on climate change (UNFCCC) defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alerts the composition of the global atmosphere and which in addition to natural climate variability observed over the comparable time periods”. Global warming refers to the recent and ongoing rise in global average temperature near the Earth’s surface. Global warming itself represents the only aspect of climate change.
Cause of climate change
Geological records stretching back millions of years indicate some large variations in climate. These have been caused by many natural factors, including the change in sun, volcanoes, Earth’s orbits and CO2 levels. However, there is good evidence to show that the current rapid warming not primarily a natural change. Rather this is likely to be due to human CO2 emissions.
Evidence of climate change
Changes in weather and climate have accompanied rising global temperature. As a result, many places have seen changes in rainfall resulting in more floods, droughts or heavy rain as well as more frequent and severe heat waves. The planet’s ocean and glaciers have also experienced some big changes- the ocean is warming and becoming more acidic, ice caps are melting, and the sea level is rising. As these and other changes become more pronounced in the coming decades, they will be likely present challenges to our society and our environment.
Arctic sea ice loss:
The decline in the Arctic sea ice, both in extent and thickness, over the last severe decades is further evidence for rapid climate change.
A change in the type distribution and coverage of vegetation may occur given change in the climate. Some causes change climate may result in increased precipitation and warmth, resulting in improved plant and growth and the subsequent of airborne CO2.
Palynology is the study of contemporary and fossil palynomorphs, including pollen. Palynology is used to infer the geological distributions of plant species, which vary under different climate.
It is the analysis of tree ring growth patterns to determine past climate variation. Wide and thick rings indicate the fertile well-watered growing period, whilst thin rings indicate the low rainfall and less than ideal growing conditions,
Analysis of ice in drilled from an ices sheet such as the Antarctic ice sheet that can be used to show the link between the temperature and global sea-level variations. The air trapped in bubbles in the ice can also reveal the CO2 variations of the atmosphere from the distant past well before modern environmental influences.
Remains are beetles common in freshwater and land sentiments. Different species of beetles tend to be found under different climate conditions. Given the extensive lineage of beetles whose genetic makeup has not altered significantly over the millennia knowledge of present climate range of different species and the age of sentiments in which remains are found past climate conditions may be inferred.
Sea level change:
Global sea-level change for much of the last century has generally been estimated using tide gauge measurements collated over long periods to give a long term average. More recently, altimeter measurements, in combination with accurately determined satellite orbits, have provided an improved measurement of global sea level.
How coronavirus lockdown have restored climate change:
COVID-19 has locked the world incomplete or partial manner. This respiratory syndrome spread by getting around pathogen career. This coronavirus infection starts from nasal secretion, and in severe cases, it leads to lungs collapse. WHO recommended social distancing to prevent coronavirus infection. Isolation is the only defence measures we have. Thousands of people in 206 countries have effected and died. Italy, America and Spain have faced devastating outbreak. This grief moment is horrifying us, but somehow we have to survive in COVID-19 pandemic.
Evidence that we are reinstalling our climate change:
We are evident in cleaner water in the murky canal- Venice. Floated fish have been observed since the world is in lockdown. Italy has faced devastating death record by a coronavirus. It was completed lock now the administration is observing relaxation in curfew. Sound benefits have been observed since the world is lock behind the doors.
Greenhouse gases emission such as CO2 and pollution have reduced. Lahore- Pakistan has recorded significant air pollution reduction and betterment of quality.
Lead developer of cool Climate network Christopher Jones said
If we can think about how to prepare for climate change like a pandemic, maybe there will be a positive outcome to all of this.
Coronavirus Statistics- Latest updates
Coronavirus has been starting to engulf people since November Wuhan, China. Indeed, this outbreak has sickened people worldwide. This is a strain of severe acute respiratory syndrome. It spread by contact with the carrier. It is a deadly type of flue that leads to death.
|Place||Confirmed cases||Recovered cases||Deaths|
|Worldwide||3.19 million||973 k||228k|
|Spain||213 k||112 k||24,543|
Coronavirus offers us a chance to rewind our life in a good way. Indeed it is a devastating disease, and the world is at the edge of the economic crash. Hence, this outbreak leaves a good impact on climate change. Air pollution seems to reduce. Cleaner water has evidenced. The ozone layer is healing. There is a chance this lockdown will improve climate change a bit more and make this world safer. Quarantine is nothing but reinstalling nature for us.
