Recent findings of the geochemist Morgan Schaller of Presselaer Poly tech Institute suggest that the current trend of temperature increase which we know as global warming may have started with a bang. Evidence such as impact debris and evidence of wildfires in North America suggests that an impact happened in the North East region of North America around 56 million years ago. This was during the Paleocene-Eocene Thermal Maximum, or PETM, which was a period of rapid warming and huge increases in carbon dioxide levels found in the atmosphere. The event is what spurred modern global warming and may have increased Co2 levels in the atmosphere by disrupting and releasing huge amounts of carbon.
This event is important because global warming is one of the biggest issues that we face today and it is extremely important to know what the origins may be because they may help us combat the issue. I think everybody should be much more informed on global warming as it is going to be one huge issue that will be faced by society in the coming decades.
There have always been doubters of science, so it's no surprise that people out right reject science pertaining to climate change. These people use myths to back up their claims but the science is against them. One common myth is "There is no general consensus pertaining to climate change." It should come as little surprise that this is indeed very false. Authors of several climate change studies such as Naomi Oreskes, Peter Doran, William Anderegg, and John Cook, published a paper that settles the dispute. In the paper the findings conclude that up to 97% of climate change experts agree that climate change is a human casued enviornmental threat. There is no disputing that climate change is real and that humans are the problem.
The second argument against climate change is that species will be able to adapt to any new conditions. Sadly this is false as the rate at which greenhouse gas emissions have been pumped into our atmosphere has increased so drastically due to human industrialization, species will not have had enough time to adapt to new conditions. These new empty slots in the world will disrupt food chains and ecosystems for a long time. Climate change really does have the potential to reshape our world.
Researchers from the University of Washington have recently discovered a new finding in Central Asian weather. The researchers found that winds native to Central Asia have been blowing in the same way for over 42 million years. These winds help share the topography and climate in Central Asia, helping form deserts in the region.
The researchers found these discoveries by studying dust patterns in the rock of the area. They found similar dust patterns which are caused directly by the wind. If these patterns remain similar over a long period of time it shows that the wind was blowing in the same pattern over this whole time period. These findings will help to predict how the ecosystem will take shape in that region in the future. If researches know that this wind will be a common factor over time they can help predict what may happen in the future and use this for further studies or to combat any dilemmas which may arise.
It has long been known that China, competitor with America for world's largest economy, has been one of the most harmful countries for the world in terms of global warming, pollution, and climate change. But in the past couple years China has tried to make up for it's global footprint and has spent billions on the world's largest reforestation program.
China's reforestation program, called Grain-for-Green, has attempted to restore 28 million hectares into wild forest in attempts to combat soil erosion and revitalize land. Forests are a very diverse and ever changing environment, but new studies by Princeton University reveal that much of the artificial forests planted by the Chinese contain only one type of tree. The research finds that having a single species of tree in the forests does nothing to enhance bio diversity and can in some cases even harm natural wildlife. The Chinese government should add more funds to the program to ensure that the job is done right - allowing for nature to take over and make these "artificial" forests wild again.
