Delegates at the COP27 held in Egypt will be basing their judgments on decades' worth of scientific information that has been published by the United Nations climate science organisation.
For Every five years or so, the Intergovernmental Panel on Climate Change (IPCC) publishes reports that represent the consensus of the world's scientists on climate change, its causes, and its effects on humans and other Biological Life.
The report from the previous year focused on the key causes of global warming which increases day by day and the fundamental concepts of climate science And Sustainable Environment.
This year Published by scientific Reports which were very Important for all of us
one in February on how the world will need to adapt to climate negative impacts, such as disturb Environment ,rising seas and disappearing animals, and another in April on strategies for "mitigating" or reducing emissions that contribute to global warming.
The following are some of the main conclusions from those reports:
The science report:
The research on the physical foundation of climate change from last year didn't hold any punches; it made it clear that people are to responsible for the global warming trend.
Additionally, it issued a warning that global warming was already perilously near to out of control.
Previously uncommon weather extremes are now more frequent, and certain locations are more at risk than others.
The authors of the report demanded immediate action to reduce methane for the first time. The IPCC had only previously focused on carbon dioxide, the most prevalent greenhouse gas.

The authors of the report demanded immediate action to reduce methane for the first time. The most prevalent greenhouse gas, carbon dioxide, had been the only focus of the IPCC up until this time.
The authors said that, with time running out, it was important to consider the advantages and disadvantages of geoengineering, which they defined as extensive interventions to change the climate, such as pumping particles into the atmosphere to block solar radiation.
The world's nations, especially the wealthy ones, were forewarned by the report that everyone needed to start preparing for the effects of the climate and adjusting to a warmer environment.
The report on adaption:
The February publication of a landmark report on how the world should get ready for a warmer reality was overshadowed by news of Russia's invasion of Ukraine.
The research recommended rich and poor countries alike to prepare for effects such as more frequent heatwaves, greater storms, and higher sea levels because climate change is already fueling extreme weather worldwide.
The research provided localised forecasts for what to expect while making it clear that different places face varying risks and repercussions.
As crops and water supplies are affected by climate change, which also poses a risk to trade and employment markets, millions of people will experience poverty and food insecurity in the years to come.
The sobering outlook for the world's poor has revived calls for a "Loss and Damage" fund, which would allow wealthy nations to reimburse poor countries for the costs associated with responding to climate-related disasters. This demand was a key one made by vulnerable countries going into the COP27 negotiations.
The report on mitigation:
It's "now or never," said the co-chair of one report, for significant emissions reductions over the coming decades to be the sole means of halting the spread of global warming.
The report hinted at how different emissions scenarios would affect the rate of global warming in the future.
Cities have a significant role in the emissions issue, but they are also a significant source of optimism and effective solutions, it claimed.
It is moving too slowly to switch to clean-burning fuels and renewable energy sources.
Strong climate action was also recommended in agriculture, where improved forest conservation and farming techniques may help reduce emissions.
For the first time, it highlighted the need for individual action and warned that climate change threatens economic growth. It urged governments to enact laws that would alter consumer and transportation habits to promote less waste and greater efficiency
