What is Climate Change

What is Climate Change

Climate change refers to long shifts in temperatures and weather patterns. There are many impacts of climate change. It can directly harm animals, destroy places. They were:  More frequent and intense drought Storms Heat waves Rising sea levels Melting glaciers and warming oceans Causes of it Heat-trapping, greenhouse gasses  Changes in the earth’s orbit and rotation.  Variations in solar…

Climate change causes Polar Vortex to venture south

this.

this right here is why it's called "climate change." Arctic warming = deep freeze in the temperate regions, because Arctic ice melting warms the ocean up there, messing with the Jet Stream and driving the cold air mass southward

stories that go into depth:

"What’s Behind the ‘Arctic Blast’ Plunging into the U.S.?" - Scientific American

"How Frigid Polar Vortex Blasts are Connected to Global Warming" - CitizenTruth.org

not only was 2023 officially the hottest year on record by a long shot (1.5°C above preindustrial levels), but this winter is on track to be one of the coldest

Interesting Times we live in, folks

The 1987 Montreal Protocol, which phased out the production and use of chemicals that were depleting the ozone layer, has long been considered one of the most successful environmental treaties in history. New research finds that the global pact achieved another unforeseen benefit: delaying the melting of Arctic sea ice.

In a study published Monday in the Proceedings of the National Academy of Sciences, researchers from the University of Exeter and Columbia University found that the implementation of the Montreal Protocol is delaying the first ice-free Arctic summer by up to 15 years. That’s because the chemicals banned under the agreement are also potent greenhouse gases.

“Our results show that the climate benefits from the Montreal Protocol are not in some faraway future: the protocol is delaying the melting of Arctic sea ice at this very moment,” Lorenzo Polvani, one of the study’s authors, said in a press release. 

The study authors ran a series of climate models based on two different scenarios: one that included levels of ozone-depleting substances that would be expected if the Montreal Protocol never existed, and another accounting for the global treaty. The researchers concluded that the protocol is postponing the first ice-free Arctic summer by a decade or more, and entirely due to the phasedown of ozone-depleting chemicals. 

The Montreal Protocol was created to address a hole in the stratospheric ozone layer over the Antarctic. The ozone layer protects the Earth from harmful ultraviolet radiation that causes skin cancer and cataracts in humans. The treaty phased out almost 100 chemicals — including aerosols used in hair spray and other products, refrigerants, and solvents — that were found to be responsible for destroying stratospheric ozone.

Those banned chemicals, collectively called ozone-depleting substances, or ODS, are also potent greenhouse gases, with up to tens of thousands times the global warming potential of carbon dioxide. The report authors estimate that 1 metric ton of avoided ODS emissions leads to 7,000 square meters (more than 75,000 square feet) of avoided Arctic sea loss. By way of comparison, 1 metric ton of carbon dioxide emissions results in about 3 square meters (about 32 square feet) of sea ice loss. 

Given the potency of ODSs as a greenhouse gas, the authors are not surprised at this outsize impact on Arctic sea ice levels. “Nonetheless, such a large mitigating impact of the Montreal Protocol on Arctic sea ice loss is remarkable if one keeps in mind that the protocol was aimed at preventing ozone depletion in the Antarctic stratosphere, and little was known of its effect on Arctic sea ice when the protocol was signed,” the authors noted.

According to their projections, the Montreal Protocol has already prevented more than half a million square kilometers (about 193,000 square miles) of sea ice loss. By 2030, that amount will rise to more than 1 million square kilometers, and to 2 million square kilometers of prevented Arctic sea ice loss by 2040.

Stop the Willow Project

Broskis I have never done a post like this and tbh, I barely get interactions on my posts so this may be a complete dud, but recent i’ve gotten an influx of followers so I’m going to use that momentum right now.

If you care even the slightest about the planet and want to piss off the boomers and ConocoPhillips (a disgusting ass oil company 🤢🤮) with a big fuck you, please please please sign the Protect The Arctic petition against the Willow Project in Alaska and the Arctic and/or the Change.org petition against the mining.

If the Biden administration does go ahead with the plan, it really will mark an end for the planet - ConocoPhillips wants to drill for petroleum and as a result, will destroy local habitats and disrupt the wildlife. It will pump over 278 MILLION tons of greenhouse gases into the air. You know, one of the biggest things currently warming our planet and killing us? The locations that they want to destroy are “…critical habitat for migrating caribou, waterfowl and other wildlife.” They have even aggressively lobbying Congress and the White House to try and pass the bill to allow for the project! It will destroy any progress towards the end for oil drilling and the destruction of the climate. The warming planet is wreaking havoc on the wildlife there (and across the world) as well.

Please, if there’s anything you take away from this, is that this is a threat to my future! To your future! To our future! Please sign the petition I’ve linked and i’ll link the change.org link as well. I’ve also included links about the project itself and how it’s detrimental to the arctic and it’s wildlife, alongside how important the arctic is as a whole to keeping the balance of Earth’s climate.

This Will be the End of Our Planet

The Willow Project has been approved by Biden but there are plans to oppose the action in court. It's our final hope and signing the petition is a way you can help. The Petition is free to sign all it takes is; your name, country and email. There is an option to donate but it is not mandatory to allow you to sign.

Please sign! The goal is to reach 4.5m+ signatures and it is currently at 3.3m

The Earth needs us. This Project will be the end of our planet.

I would like to announce to everyone that it is currently

That is correct, you’ve read that right:

Degree :))

Not to catastrophize without cause, but if there has been a clearer sign of climate apocalypse (in this part of the U.S. anyway). I do not recall it 🙂

We’ve all heard climate change is bad, but it could be even worse than we feared. As the permafrost in the Arctic thaws, potentially deadly viruses could be released.

As Arctic sea ice melts away, so does the polar bear's food supply.

Got a pre-interview for a job at a scientific journal that I wasn't even really gonna let myself want too badly 🤞 wish me luck!!!
