Over fifty years of data show a peak in PFAS (also known as "forever chemicals") content in seabird eggs in the 90s, followed by a decrease as regulations went into effect. The most recent findings show a 70% decrease of most common PFAS.

The federal government is moving to add PFAS, a class of thousands of chemicals used in a wide range of products from food containers to clothing, to the official list of toxic substances, in light of growing scientific and public concern about the substances in Canada and around the world. PFAS, or per- and polyfluoroalkyl substances, are man-made chemicals used for their water and heat resistant properties. They are widely used in many everyday products — such as packaging, cosmetics and textiles — along with industrial uses like water-repellent coatings and firefighting foam.

Contamination of ground, surface and drinking water by perfluoroalkyl and polyfluoroalkyl substances (PFAS) affects millions of people worldwide. A promising new method developed by Flinders University scientists paves the way to help remove the most difficult-to-capture variants of these persistent pollutants from water. The research team, led by Flinders ARC Research Fellow Dr. Witold Bloch, has discovered adsorbents that effectively capture PFAS, including short-chain forms that are especially difficult to remove using existing technologies. The study, published in the Angewandte Chemie International Edition , showcases the use of a nano-sized molecular cage that acts as a highly selective "PFAS trap."

President Biden announced the cancellation of a student loan debt for a further 277,000 Americans. This brings the number of a Americans who had their debt canceled by the Biden administration through different means since the Supreme Court struck down Biden's first place in 2023 to 4.3 million and a total of $153 billion of debt canceled so far. Most of these borrowers were a part of the President's SAVE Plan, a debt repayment program with 8 million enrollees, over 4 million of whom don't have to make monthly repayments and are still on the path to debt forgiveness.

President Biden announced a plan that would cancel student loan debt for 4 million borrowers and bring debt relief to 30 million Americans The plan takes steps like making automatic debt forgiveness through the public service forgiveness so qualified borrowers who don't know to apply will have their debts forgiven. The plan will wipe out the interest on the debt of 23 million Americans. President Biden touted how the plan will help black and Latino borrowers the most who carry the heavily debt burdens. The plan is expected to go into effect this fall ahead of the election.

President Biden and Vice-President Harris announced the closing of the so-called gun show loophole. For years people selling guns outside of traditional stores, such as at gun shows and in the 21st century over the internet have not been required to preform a background check to see if buyers are legally allowed to own a fire arm. Now all sellers of guns, even over the internet, are required to be licensed and preform a background check. This is the largest single expansion of the background check system since its creation.

The EPA published the first ever regulations on PFAS, known as forever chemicals, in drinking water. The new rules would reduce PFAS exposure for 100 million people according to the EPA. The Biden Administration announced along side the EPA regulations it would make available $1 billion dollars for state and local water treatment to help test for and filter out PFAS in line with the new rule. This marks the first time since 1996 that the EPA has passed a drinking water rule for new contaminants.

The Department of Commerce announced a deal with microchip giant TSMC to bring billions in investment and manufacturing to Arizona. The US makes only about 10% of the world's microchips and none of the most advanced chips. Under the CHIPS and Science Act the Biden Administration hopes to expand America's high-tech manufacturing so that 20% of advanced chips are made in America. TSMC makes about 90% of the world's advanced chips. The deal which sees a $6.6 billion dollar grant from the US government in exchange for $65 billion worth of investment by TSMC in 3 high tech manufacturing facilities in Arizona, the first of which will open next year. This represents the single largest foreign investment in Arizona's history and will bring thousands of new jobs to the state and boost America's microchip manufacturing.

The EPA finalized rules strengthening clean air standards around chemical plants. The new rule will lower the risk of cancer in communities near chemical plants by 96% and eliminate 6,200 tons of toxic air pollution each year. The rules target two dangerous cancer causing chemicals, ethylene oxide and chloroprene, the rule will reduce emissions of these chemicals by 80%.

the Department of the Interior announced it had beaten the Biden Administration goals when it comes to new clean energy projects. The Department has now permitted more than 25 gigawatts of clean energy projects on public lands, surpass the Administrations goal for 2025 already. These solar, wind, and hydro projects will power 12 million American homes with totally green power. Currently 10 gigawatts of clean energy are currently being generated on public lands, powering more than 5 million homes across the West. 

The Department of Transportation announced $830 million to support local communities in becoming more climate resilient. The money will go to 80 projects across 37 states, DC, and the US Virgin Islands The projects will help local Infrastructure better stand up to extreme weather causes by climate change.

"The sleeping giant of the US Environmental Protection Agency (EPA) has stirred.

In the past month, an avalanche of anti-pollution rules, targeting everything from toxic drinking water to planet-heating gases in the atmosphere, have been issued by the agency. Belatedly, the sizable weight of the US federal government is being thrown at longstanding environmental crises, including the climate emergency.

On Thursday [May 18, 2023], the EPA’s month of frenzied activity was crowned by the toughest ever limits upon carbon pollution from America’s power sector, with large, existing coal and gas plants told they must slash their emissions by 90% or face being shut down.

The measure will, the EPA says, wipe out more than 600m tons of carbon emissions over the next two decades, about double what the entire UK emits each year. But even this wasn’t the biggest pollution reduction announced in recent weeks.

In April, new emissions standards for cars and trucks will eliminate an expected 9bn tons of CO2 by the mid-point of the century, while separate rules issued late last year aim to slash hydrofluorocarbons, planet-heating gases used widely in refrigeration and air conditioning, by 4.6bn tons in the same timeframe. Methane, another highly potent greenhouse gas, will be curtailed by 810m tons over the next decade in another EPA edict.

In just a few short months the EPA, diminished and demoralized under Donald Trump, has flexed its regulatory muscles to the extent that 15bn tons of greenhouse gases – equivalent to about three times the US’s carbon pollution, or nearly half of the entire world’s annual fossil fuel emissions – are set to be prevented, transforming the power basis of Americans’ cars and homes in the process...

If last year’s Inflation Reduction Act (IRA), with its $370bn in clean energy subsidies and enticements for electric car buyers, was the carrot to reducing emissions, the EPA now appears to be bringing a hefty stick.

The IRA should help reduce US emissions by about 40% this decade but the cut needs to be deeper, up to half of 2005 levels, to give the world a chance of avoiding catastrophic heatwaves, wildfires, drought and other climate calamities. The new rules suddenly put America, after years of delay and political rancor, tantalizingly within reach of this...

“It’s clear we’ve reached a pivotal point in human history and it’s on all of us to act right now to protect our future,” said Michael Regan, the administrator of the EPA, in a speech last week at the University of Maryland. The venue was chosen in a nod to the young, climate-concerned voters Joe Biden hopes to court in next year’s presidential election, and who have been dismayed by Biden’s acquiescence to large-scale oil and gas drilling.

“Folks, this is our future we are talking about, and we have a once-in-a-generation opportunity for real climate action,” [Michael Regan, the administrator of the EPA], added. “Failure is not an option, indifference is not an option, inaction is not an option.” ...

It’s not just climate the EPA has acted upon in recent months. There are new standards for chemical plants, such as those that blight the so-called "Cancer Alley" the US, from emitting cancer-causing toxins such as benzene, ethylene oxide and vinyl chloride. New rules curbing mercury, arsenic and lead from industrial facilities have been released, as have tighter limits on emissions of soot and the first ever regulations targeting the presence of per- and polyfluoroalkylsubstances (or PFAS) in drinking water.” ...

For those inside the agency, the breakneck pace has been enervating. “It’s definitely a race against time,” said one senior EPA official, who asked not to be named. “The clock is ticking. It is a sprint through a marathon and it is exhausting.” ...

“We know the work to confront the climate crisis doesn’t stop at strong carbon pollution standards,” said Ben Jealous, the executive director of the Sierra Club.

“The continued use or expansion of fossil power plants is incompatible with a livable future. Simply put, we must not merely limit the use of fossil fuel electricity – we must end it entirely.”"
