The Intergovernmental Panel on Climate Change is alarming. The current climate liberalization processes are unprecedented. Some changes, such as the continuous rise in sea level, which are irreversible, have already begun. This report, “Climate Change 2021: The Scientific Foundations”, is the first part of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, which will be completed in 2022.
Acceleration in temperature rise
The Paris Accords, to halt climate change, planned to limit temperature rise to 1.5 degrees. IPCC scientists are clear on the subject: As it stands, it would be impossible to limit warming to 1.5°C, or even 2°C. Only immediate, rapid and large-scale reductions in greenhouse gas emissions can contain this phenomenon.
With an increase of 1.5°C, we will see an increase in extreme heat waves, longer hot seasons, and shorter cold seasons. With a temperature increase of 2°C, temperature peaks often reach critical tolerances for agriculture and health.
The human impact on global warming is questioned by civil society and the scientific community. The theory that it is of natural origin is espoused by climate skeptics and some politicians around the world.
The IPCC report states that anthropogenic greenhouse gas emissions are responsible for 1.1°C of warming since the early 1990s.
“It has been clear for decades that the Earth’s climate is changing, and the role of human influence on the climate system is indisputable,” said Mr. Mason Delmott.
Expect an increase in natural disasters
This new report reflects key developments in the science of referral. This science explains the consequences of climate change in the intensification of specific weather and climate phenomena, such as extremes and natural disasters.
We also learn that the water cycle is changing. This will lead to heavy rains, a marked increase in the intensity and number of floods, as well as more severe droughts in many areas.
Coastal regions will experience a continuous rise in sea level throughout the twenty-first century. This increase will contribute to more frequent and intense coastal flooding in low erosion-prone areas. Some extreme once-in-100-year events could occur every year by the end of the century.
“To stabilize the climate, it will be necessary to aggressively, rapidly and sustainably reduce greenhouse gas emissions and achieve zero carbon dioxide emissions,” Chai said.
What to remember
The five points of caution in the report:
Climate change is unprecedented for hundreds of thousands of years
– We will exceed 2 degrees Celsius of global warming, which is the threshold that will generate irreversible liberalization
Rising water levels are ruthless! Even with immediate actions from us –
Expect an increase in extreme events
Man is the origin of global warming. Since 1990, greenhouse gas emissions have been responsible for a 1.1°C warming
The four points of stopping climate change:
Quickly achieve zero CO2 emissions
– Reducing methane emissions
Developing renewable energies and sustainable transport
– Restriction of the transport of goods
