A new study shows that the West Antarctic Peninsula is experiencing some of the most rapid climate change on Earth, featuring dramatic increases in temperatures, retreats in glaciers and declines in sea ice. The Southern Ocean absorbs nearly half of the carbon dioxide -- the key greenhouse gas linked to climate change -- that is absorbed by all the world's oceans. The study tapped an unprecedented 25 years of oceanographic measurements in the Southern Ocean and highlights the need for more monitoring in the region. The research revealed that carbon dioxide absorption by surface waters off the West Antarctic Peninsula is linked to the stability of the upper ocean, along with the amount and type of algae present. A stable upper ocean provides algae with ideal growing conditions. During photosynthesis, algae remove carbon dioxide from the surface ocean, which in turn draws carbon dioxide out of the atmosphere. From 1993 to 2017, changes in sea ice dynamics off the West Antarctic Peninsula stabilized the upper ocean, resulting in greater algal concentrations and a shift in the mix of algal species. That's led to a nearly five-fold increase in carbon dioxide absorption during the summertime. The research also found a strong north-south difference in the trend of carbon dioxide absorption. The southern portion of the peninsula, which to date has been less impacted by climate change, experienced the most dramatic increase in carbon dioxide absorption, demonstrating the poleward progression of climate change in the region.

More than 300 businesses have signed an open letter calling on the Biden administration to reduce greenhouse gas emissions in the United States to at least half of 2005 levels by 2030. That would nearly double a previous target set by former President Barack Obama in 2015, who pledged a 25 to 28% reduction by 2025.

The United States is not currently on track to meet either goal.

The signatories include some of largest companies in the United States, including Walmart, Apple, McDonald's and Starbucks. "A bold 2030 target is needed to catalyze a zero-emissions future, spur a robust economic recovery, create millions of well-paying jobs, and allow the U.S. to 'build back better' from the pandemic," the letter said, echoing the president's economic recovery slogan.

A 50% reduction target would put the Biden administration in line with what groups such as the United Nations and National Academies of Science say is necessary to mitigate the worst impacts of climate change.

In a March statement calling for the same reductions target, the environmental advocacy group Natural Resources Defense Council said such a plan would "help pull the country out of the pandemic-induced recession by putting millions of Americans to work" and inspire more ambitious international climate action ahead of a major United Nations climate conference this November.

Like President Joe Biden's campaign promise to guide the United States to carbon-neutrality by the middle of the century, a 50% emissions reduction target would require steeper emissions cuts than the country has ever achieved.

In 2019, greenhouse gas emissions were approximately 13% below 2005 levels, a decrease of just 1.8% from the previous year.

The Biden administration has identified climate action as one of its top four priorities and has named prominent, experienced Washington insiders, including former Secretary of State John Kerry and former EPA administrator Gina McCarthy, to oversee climate policy efforts at the White House.

As NPR's Danielle Kurtzleben has previously reported, activists on the left are cautiously optimistic about the administration's climate plan after expressing doubts about Biden's climate record during the Democratic primary.

Sunrise Movement, a youth-led climate group that champions the Green New Deal, gave candidate Biden's initial climate plan an "F" grade. Now, the group's executive director Varshini Prakash is publicly celebrating his administration's latest climate-focused $2 trillion infrastructure bill — including its commitment to spend 40% of the infrastructure plan's money on disadvantaged communities and launch a jobs program called the Civilian Climate Corps.

New York Democratic Rep. Alexandria Ocasio-Cortez told NPR earlier this month that she feels that Biden has ultimately come around to the side of progressives on climate issues. She said: "As much as I think some parts of the party try to avoid saying 'Green New Deal' and really dance around and try to not use that term, ultimately, the framework I think has been adopted."

The emphasis on climate comes as a sharp departure from the Trump administration, which withdrew the United States from the Paris Agreement and set no emissions reductions targets.

Signatories to the Paris deal, which Biden rejoined on the day he was sworn into office, are all required to set these targets — formally known as nationally determined contributions, or NDCs.

The agreement also encourages nations to revise their goals every five years, in hopes that the proposals become more ambitious as the cost of environmental reform goes down.

Since the Paris agreement was first agreed to in 2015, though, just fifty of the deal's nearly 200 signatories have submitted revised targets. A recent U.N. analysis of international climate action found that many countries were doing far too little to reduce emissions for the world to avoid the worst effects of climate change.

So far, the White House has not indicated exactly how ambitious their plan will be. An announcement is expected in the coming days as the White House prepares for its Earth Day climate summit with world leaders, scheduled for Thursday, April 22.

Current federal tax provisions have minimal net effect on greenhouse gas emissions, according to a new report from the National Research Council.

There is no substitute for dramatic reductions in greenhouse gas emissions to mitigate the negative consequences of climate change, a National Research Council committee concluded in a two-volume evaluation of proposed climate-intervention techniques.

There would not be sufficient benefit to updating estimates of the social cost of carbon (SCC) within a year based only on the revision of a specific climate parameter in the existing framework used by the government’s interagency group to measure the SCC, says a new interim report from the National Academies of Sciences, Engineering, and Medicine.

To estimate the social cost of carbon dioxide for use in regulatory impact analyses, the federal government should use a new framework that would strengthen the scientific basis, provide greater transparency, and improve characterization of the uncertainties of the estimates, says a new report by the National Academies of Sciences, Engineering, and Medicine.

The U.S. Global Change Research Program (USGCRP) asked the National Academies of Sciences, Engineering, and Medicine to review the draft Fourth National Climate Assessment (NCA4) – a congressionally mandated report that evaluates the state of climate science and the broad range of impacts of climate change in the United States every four years – and the draft Second State of the Carbon Cycle Report (SOCCR2) – a report that feeds into the overall assessment process developed by the USGCRP.

In addition to jet propellant 8 (JP8), the U.S. Army should incorporate the use of diesel and renewable biodiesel as the primary sources of energy brought to the battlefield through 2035 to maximize warfighting capabilities, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The U.S. should undertake a new research program to better understand the potential risks and benefits of ocean-based interventions to remove or sequester carbon dioxide from the atmosphere and learn how these methods could be used to mitigate the impacts of climate change.

Experts discuss the future of ocean-based approaches to carbon dioxide removal — including the ethics of investigating proposed strategies, how research can respond to public concerns, and what we need to know to make informed climate decisions.

In an interview, NAE President John Anderson discusses the national and global transition to net-zero carbon emissions and how engineers — and NAE in particular — can support that shift. Energy Transitions is the theme of NAE’s annual meeting this year, taking place Oct. 2-3.

Life cycle assessments of low-carbon transportation fuels — such as electricity, biofuels, or hydrogen — are valuable tools for measuring environmental impacts, but uncertainties remain in the models that are currently used, and further research should be conducted to strengthen their reliability.

As part of the shift to a net-zero carbon emissions economy, industry and government should begin planning for the deployment of carbon dioxide utilization systems to turn captured CO2 into useful products, such as aviation fuel and aggregates for construction.

For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power -- resulting in longer battery life, faster wireless communication and faster processing speeds for devices like smartphones and laptops.
