carbon dioxide – Paranormal Activity

Climate Scientist responds to Sabine Hossenfelder on Climate Sensitivity

ClimateAdam — Fri, 02 Feb 2024 15:36:48 +0000

How hot will our planet actually get? Climate scientists try to answer this question by evaluating the “climate sensitivity”. And if you’ve watched the recent Sabine Hossenfelder, you may be left with the impression that climate change wasn’t much to worry about… but now it is. So I’m here to explain what the evidence is actually showing us, and why the situation is a little more nuanced than Sabine’s commentary may have suggested. And crucially I break down how climate scientists arrive at a number for the crucial “climate sensitivity”, to give us a sense for how much global warming we’re in for.

Climate change – Averting catastrophe | DW Documentary

DW Documentary — Thu, 13 Jul 2023 16:00:37 +0000

In the last 30 years, CO2 emissions have increased by 60 percent worldwide. The most pressing problem facing our civilization is global warming. What solutions could there be? This documentary accompanies activists in their efforts to combat climate change.

According to scientists, if by the year 2100 the global temperature has risen more than 1.5 degrees Celsius on levels recorded in the year 1850, the consequences could be devastating for people and the environment. But will we manage to achieve this ambitious goal? Around the world, politicians, companies, laboratories and universities are struggling to find solutions.

The film team visits climate rescuers in Sudan, Indonesia and Europe. Their inventive spirit cools buildings, connects countries with green electricity lines or sucks carbon dioxide out of the atmosphere. Their work helps determine the living conditions of generations to come.

Every time the women of Shagra plant an acacia seedling in the sand of Darfur, it is an occasion of great joy in the Sudanese village. The tree will drive its roots 100 meters into the ground and be better able to withstand the droughts in the Sahel than most other plants. It will secrete gum sap when women scratch the bark after a few years. The sale of gum arabic will alleviate poverty in the village.

65,000 acacias are already growing in Darfur: a blessing for the bitterly poor region, as well as a carbon dioxide reservoir that can help limit global warming.

A History of Earth's Climate

SciShow — Mon, 27 May 2013 16:30:36 +0000

Earth had a climate long before we showed up and started noticing it and it’s influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we’re gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we’re experiencing now is different than anything this planet has encountered before. So, let’s take a stroll down Climate History Lane and see if we can find some answers to a question that’s been bugging Hank a lot lately – just how much hot water are we in?
