There is no more doubting or questioning it – #global warming is happening according to scientific consensus, which claims humans are the cause. As a matter of fact, as per the head author on an influential study on global warming, the notion that people are the cause potentially passed 99 percent. This number could actually increase once doubts are cleared up through additional research.
Global Warming Can No Longer Be Denied
All-encompassing historical data was utilized to demonstrate (in three studies presented by #Nature and Nature Geoscience) that over the last 2,000 years, there has never been a period of time when temperature variations have been as quick as they have been in recent decades. Today, the negative impacts of global warming we have been warned about are very apparent. Global warming can no longer be denied.
It was formerly believed that equally intense global warming-related changes could have taken place in the past, for instance, in the Medieval Climate Anomaly and Little Ice Age periods. However, based on the three previously mentioned studies, certain shifts would not have occurred in more than half the planet at any particular time. These studies utilized reconstructions which were based upon 700 proxy registers of temperature alterations, such as ice, sediment, and trees from all continents.
Evidence of Global Warming
You likely have heard of the heatwave happening this summer in Europe. Let’s go back to the Little Ice Age (1300 to 1850). The 15th century is when this period reached an extreme point in the Pacific Ocean. In the 17th century, it reached an extreme point in Europe. But since the late 20th century, records have been broken each year across the planet. The heatwave in Europe is just one example of global warming at play. If one wants evidence of global warming, all they have to do is look at the current temperatures.
What has caused significant temperature shifts in recent history? One of the studies says volcanic eruptions have been a main cause. This would explain global fluctuations which took place during the first part of the 18th century, when the world transitioned from one which was volcanically chilled to one with a warmer climate due to human emissions. A study mentions how this has become very clear since the late 20th century, as temperatures have gone up fast over the course of 20 years – as a matter of fact, they have risen the most rapidly in this amount of time over the last two thousand years.
Industrial emissions have caused uncommon warming temperatures, in line with the authors of these studies.
The University of Bern and the Pages 2K consortium of climate scientists, Stefan Brönnimann, mentioned how there is not any uncertainty left, and this has been clearly demonstrated through many studies which address the climate system. Humans are, in fact, causing #climate change in ways never seen before.
The studies show that current changes are not part of a natural cycle. Climate change deniers need to face the truth, as there is a huge difference between localized and regional changes in the climate, as touched upon by professor of climatology at University College London, Mark Maslin.
There is agreement among scientists studying climate change in many studies that things such as chimneys, forest clearance, car exhausts and so on are causing global warming.
Extreme Weather and Climate Change
Academics studying the climate and climate change cannot deny what is happening to our planet. As per the lead author of a study on “#consensus about consensus,” #John Cook, there was a 99 percent consensus among scientists back in 2011 that human beings are causing global warming, in accordance with a 20-year study. So, there is more agreement now than there was at first. There has been strong research on global warming and climate change since, in addition to increasing extreme weather conditions and heatwaves.
Cook mentioned how know-how in science studying climate change is increasing. Consequently, agreement regarding global warming being caused by humans is increasing, too. Unfortunately, there are still climate change deniers but on the plus side, public understanding is increasing. This is important.
We must take care of our planet, and the first step is to accept that it is much more difficult to deny climate change and global warming are occurring today.
