The year 2023 was by far the warmest in Earths recorded history, and perhaps in the past 100,000 years , shattering the previous record set in 2016 by 0.27C (0.49F). According to recent data from NOAAs National Center for Environmental Information, 2024 is likely to be even warmer than 2023. But why were 2023 and 2024 so warm?
The next week has the potential to bring important developments for international governance of marine carbondioxide removal (CDR). seaweed) for carbon storage. The post Upcoming Developments in International Governance of Marine CarbonDioxide Removal first appeared on Climate Law Blog.
It shows the atmospheric concentrations of carbondioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. I wrote a post on the IPCC’s summary for policymakers (SPM) on this in 2023, but without much effect.
The potential collapse of the AMOC—which could happen within this century, or be triggered within this century and play out over a longer timeframe—comes as a result of climate change caused by additional heat-trapping emissions like carbondioxide in the atmosphere. But what exactly would cause the AMOC to collapse?
For the first time, the Arctic Report Card assessed that the Arctic is faltering as a reliable area for storing carbon away from the atmosphere ( Natalie et al., It was its first failing grade after thousands of years holding onto more carbon than released to the atmosphere. in Arc2024 ). in Arc2024 ).
At a moment of unprecedented uncertainty for net zero, biochar-based carbondioxide removal (CDR) is set to reshape the global carbon market. Driven by integrity concerns around avoided-emissions credits, the value of the global carbon market plunged from $1.87 billion in 2023 to $723 million in 2024.
As NASA explains , over most of the last 800,000 years, until humans started burning fossil fuels, atmospheric CO 2 concentrations basically never went below 180ppm and never went above 280ppm. In the last sixty years, the amount of carbondioxide in the atmosphere has grown 100 times faster than it did at the close of the last ice age.
Although in its early stages, carbondioxide removal (CDR) techniques – i.e., techniques that remove and store carbondioxide from the atmosphere – have gained traction in recent years as a climate change mitigation strategy. Australia is another example.
The team, led by atmospheric scientist Ning Zeng of the University of Maryland in the US, found that the wood had only lost 5% of its carbon compared with a freshly cut Eastern red cedar log. When plants decompose or are burnt, they release the carbondioxide (CO 2 ) they had absorbed from the atmosphere.
In 2023 he and his colleagues published a study that showed “multiple lines of evidence” indicating much of northwestern Greenland was ice-free around 400,000 years ago. The concentration of carbondioxide in the atmosphere then was less than 300 parts per million. Today we’re at 428 parts per million.
Rather, our knowledge has grown over 168 years, since an American scientist first discovered the heat-trapping properties of carbondioxide. C if the CO 2 concentration in the atmosphere is doubled, very close to current estimates based on more sophisticated modeling. Climate change is no fad or Johnny-come-lately in science.
Additionally, much of the money appropriated for conservation programs under the IRA was specifically set aside to fund conservation practices that are aimed at improving soil carbon, reducing nitrogen losses, and sequestering carbondioxide. A more detailed break down of conservation funding under the IRA is available here.
Methane is a highly potent greenhouse gas -- 80 times more potent than carbondioxide in the first 20 years after it is released into the atmosphere. In 2023, Pennsylvania's oil and gas operations emitted over 1 million metric tons (MMT) of methane. A strong majority of Pennsylvanians support action on climate.
In 2023, he said the the hype over wildfires is just hype to justify climate policies. Climate mockery at Department of Energy And then we have the reported layoff of between 1,200 and 2,000 workers at the Energy Department , now run by Chris Wright, a former CEO of one of the nations largest fracking companies.
This is the second year in a row in which the land carbon sink has nearly vanished due to climate-related stressors, and would explain why 2024 saw a record jump in the concentration of CO₂ in the atmosphere. Forests, grasslands and other ecosystems on land take up CO₂ from the atmosphere as they grow.
Among other cuts, the budget proposes: Cancellation of $15.247 billion in Infrastructure Investment and Jobs Act funds (which the document labels Green New Scam funds) for unreliable renewable energy, removing carbondioxide from the air, and other costly technologies burdensome to ratepayers and consumers.
When 10 inches of rain fell in 24 hours in July 2023, it flooded Willow Creek, damaged 60 homes, and took acres of cropland with it. Amid the trees, soil in the paddocks would retain moisture during droughts, while capturing and storing climate-warming carbondioxide from the atmosphere.
Some reporters like Arcelia Martin at Inside Climate News drew the climate connection by the second graph, writing that climate scientists said the torrential downpours on July 4 exemplify the devastating outcomes of weather intensified by a warming atmosphere.
I reviewed ExxonMobil’s two most recent reports (2023/2024) to evaluate the scientific rigor of its claims. While the IPCC mentions the value of CCS, the 2023 synthesis report also notes, “Currently, global rates of CCS deployment are far below those in modelled pathways limiting global warming to 1.5°C Who needs units anyway?
Gasoline use in 2023 in California dropped about 15 percent from a peak in 2005, with consumption dropping over two billion gallons per year Annual gasoline consumption per person in California has also dropped, from almost 450 gallons per year per person to below 350 gallons per person. pounds of carbondioxide emissions per gallon.
Exploring this new dataset ExxonMobil, Shell, Chevron, BP, and ConocoPhillips have made headlines in recent years for the enormous profits they are raking in—more than $100 billion in 2023 alone. This is because cumulative emissions of carbondioxide (CO2) are key for understanding global temperature rise.
By Anders Lorenzen It was long expected that 2023 was going to be the warmest year ever recorded since records began. Every month since June 2023 has on a global level been the warmest compared with corresponding months in previous years. The data demonstrated that on average 2023 was a whole 1.48
But summer 2023 was when the climate crisis got real for a lot of people. The Inflation Reduction Act is directing $20B toward climate-resilient agriculture Reducing heat-trapping carbondioxide (CO 2 ) emissions through policies that drive renewable energy and clean transportation has well known benefits.
There is a recording of the IPCC Press Conference – Climate Change 2023: Synthesis Report for those who are interested in watching an awkward release of the report. I had to look up the acronym “CDR” (Carbondioxide removal). Humans work hard to add greenhouse gases such as CO 2 into the atmosphere.
Support for carbondioxide removal (CDR) is growing globally. In its Sixth Assessment Report , released last year, the Intergovernmental Panel on Climate Change (IPCC) concluded that global carbondioxide emissions must reach net-zero by the early 2050s to limit warming to 1.5 By Carolina Arlota and Korey Silverman-Roati.
The Sabin Center published a new report today recommending actions that federal agencies could take to ensure safe and responsible permitting and regulation of ocean carbondioxide removal (CDR) research in U.S. A variety of ocean-based CDR approaches—i.e., Those activities could raise a host of legal issues. and the U.S.
Author: Ieva Blazauskaite (Ivy Protocol, Marketing Lead) To meet the climate goals outlined by the Paris Agreement, a unified approach, combining both Nature-Based Solutions (NBS) and Engineered Carbon Removal Solutions is crucial. The Engineered Carbon Removal On the other end of the spectrum, we find tech-savvy carbon removal engineers.
Each credit one metric ton of carbondioxide equivalent pollution below the standard. I’ve written recently about why a Cap on Vegetable Oil-Based Fuels Will Stabilize and Strengthen California’s Low Carbon Fuel Standard , which addresses the bio-based diesel credits. Source California Air Resources Board.
On September 21, 2023, the Biden administration outlined plans to expand federal agencies’ consideration of the social cost of carbon—a metric for the economic cost of each additional ton of carbondioxide emitted to the atmosphere. The directive is, nonetheless, significant.
By Anders Lorenzen The emissions from methane , a powerful greenhouse gas (GHG) with 80 times the warming potential of carbondioxide (CO2) rose in 2023 despite several pledges and initiatives to reduce emissions. One super-emitting event, detected by satellites, was a well blowout in Kazakhstan that lasted more than 200 days.
In 1970, electrochemist (and purported alchemist ) John Bockris predicted a global shift to the hydrogen economy , a phrase that describes widespread adoption of hydrogen to facilitate a shift to a low-carbon society. kg of carbondioxide emissions. kg of carbondioxide emissions per kilowatt-hour of energy produced.
The frightful phenomenon is on a scale proportional to and correlated with the climate altering changes in Earth’s atmosphere. Gases from the atmosphere get absorbed by the ocean and gases dissolved in the ocean are released into the atmosphere. Posted: September 12, 2023] PA Environment Digest
This editorial first appeared in the Scranton Times on March 10, 2023 -- As regulators investigate and lawmakers lament the Feb. Methane is a powerful contributor to atmospheric warming. In addition to harming the atmosphere, the massive leak also caused short-term health problems for nearby residents. “It
DEP responded immediately to the well control emergency, maintained a 24/7 onsite presence for 15 days, and continued to expend significant resources to investigate and oversee remedial activities at the site throughout 2023. The impact of methane is over 25 times greater than carbondioxide at trapping heat in the atmosphere.
Guest Post by Sam Leuthold , 2023-2024 Sustainability Leadership Fellow, and Department of Soil and Crop Sciences and the Graduate Degree Program in Ecology at Colorado State University Over the course of the last two decades, there has been a shift in the general popularity of agricultural soils. So why the hype around agricultural soils?
With atmosphericcarbondioxide levels on the rise, “innovative research that finds ways to transform CO 2 in the atmosphere into something positive is more important than ever.” BETO notes that the long-term challenge of the research will be scaling up scientific findings into commercial applications.
Leubke will explain the basics of carbon capture and storage (CCS) and how both point-source CCS and direct air capture (DAC) can help the U.S. reduce its carbondioxide (CO2) atmospheric levels.
We are thrilled to share stories from our climate work that highlight progress and learnings from 2023. This is a direct result of excessive greenhouse gas emissions, including carbondioxide (CO2) and methane (CH4), and the exploitation of natural resources for capitalistic gain.
DCNR's Conservation and Natural Resources Advisory Council will host a 2-part online CNRAC Conversation on Below and Above: Storing Carbon In The Pennsylvania Landscape. This webinar series explores opportunities to reduce carbondioxide emissions through underground carbon storage and aboveground carbon sequestration.
“Participants in the GreenChill Partnership and Store Certification Programs have been leading the industry in environmentally friendly refrigeration practices, and EPA annually honors their achievements at both the corporate and individual store certification level,” said Paul Gunning, Director of EPA’s Office of Atmospheric Protection.
Methane has 80 times the warming potential of carbondioxide (CO2). Over 50 major independent and state-owned oil and gas – companies pledged at the UN climate summit, COP28, held late 2023, to reduce their methane leaks to near zero by the end of this decade.
