Global warming has increased globally over the last six years. With the melting of the ice rocks at the arctic and Antarctic poles, there is a need to worry. The frequent fires at the Amazon forest have also been witnessed in recent years. It is therefore impossible to miss a global warming thesis in light of all these developments. These developments modify weather balances and ecosystems for a long time. Global warming continues to be the greatest challenge of the 21st century with the industrial and technological innovations taking place.

Please enter something. Global Warming: Hoax or fact? These are just a few statements that can be heard in numerous articles and videos online nowadays. They claim to be prophesizing a gruesome end for humanity due to the excess amount of greenhouse gases we release into the atmosphere, consequently giving rise to the phenomenon known as 'Global Warming'. Most people might think that global warming is caused by human activity; however, environment have caused global warming itself as a result of climate changes, nature disaster, and changes in the deep… Human activities produce greenhouse gases that accumulate in the atmosphere and cause problems our planet faces today. Global warming can do more than just melt polar ice and change weather patterns throughout the world.
As the weather is up and down, cold one day and then extremely hot the next, no matter the short changed in weather, climate is a huge deal breaker for the future of the polar bear. Are humans responsible for the future of the big white bears that roam around on ice all day trying to survive? Maybe we are, maybe we are not, but polar bears are diminishing due to fluctuating environmental changes, gas and oil activities like drilling in the Atlantic Ocean, and their survival rate is decreasing as a result of starvation.
Since then, accelerating greenhouse gas emissions have contributed to global average temperatures that are now surpassing 1 degree C above the midth century. The team worked in collaboration with scientists from research institutions throughout the world to reconstruct the global average temperature over the Holocene Epoch—the period following the Ice Age, beginning about 12, years ago. This study, based on a major new compilation of previously published paleoclimate data, combined with new statistical analyses, shows more confidently than ever that the millennial-scale global cooling began approximately 6, years ago. Earlier this year, an international group of 93 paleoclimate scientists from 23 countries—also led by Kaufman, McKay, Routson and Erb— published the most comprehensive set of paleoclimate data ever compiled for the past 12, years, compressing 1, data records based on samples taken from sites globally. At each site, researchers analyzed ecological, geochemical and biophysical evidence from both marine and terrestrial archives, such as lake deposits, marine sediments, peat and glacier ice, to infer past temperature changes.
