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 ). Methane releases were sustained as well.
The Detroit cloudburst was the result of a nasty weather combination—a cold front sweeping across the Midwest, plus a mass of humidity hanging over the city—which promises to be all the more powerful as the climate continues to warm. Similarly, the annual number of extreme storms in southern Michigan doubled between 1964 and 2013.
Attribution science , which is about understanding the role of climatechange versus natural weather patterns and climate variability, can help us better understand the connections between extreme weather and climatechange, provide new insight into what specific emissions are driving the worst impacts, and help shape climate solutions.
I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on ClimateChange (IPCC) on August 9th. The problems with the SPM are similar those from the previous fifth assessment report which prompted me to write a post in 2013.
The Intergovernmental Panel on ClimateChange has concluded that CDR will be needed, alongside deep emissions cuts, to limit global warming to 1.5 But, in 2013, the parties to the London Protocol adopted an amendment that is intended to be. The 2013 amendment has not yet entered into force.
And since the first IPCC estimates published in 2013, we have learned a lot and have gotten much better at estimating remaining carbon budgets. How have these estimates changed since previous reports? IPCC reported carbon budgets for the first time in 2013. in 2018, but they represent a significant update since AR5 in 2013.
Since starting with Environmental Defence in January, I’ve been grappling with an updated version of those song lyrics: “Why we must talk about climatechange when everything is burning?” Given the human cost of climatechange, you might think that talking about it while it is ravishing our nation would be easy.
Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming. In North America, the land carbon sink between 2004 and 2013 offset roughly 39% of fossil fuel emissions , but varied substantially year to year.
To meet emissions goals and avoid the worst impacts of climatechange, this trend will need to accelerate over the coming decades. Only around 50,000 EVs were on the road in 2013, but there are now over 1.5 Burning gasoline in an automobile produces carbon dioxide, the primary cause of climatechange.
are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.
But it emphasizes an important point about the relationship between SST and hurricane behavior in general: The hurricane response to SST changes depends on what caused the SST changes ( Emanuel and Sobel 2013 ). In particular, they don’t just respond to SST changes, but also how the atmospherechanges as the SSTs change.
I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. Instead, they chose to hide the structural uncertainty in the MSU retrievals (the TMT trends for 1979-2013 in UAH v5.5 TLT trends for 1979-2013 were 0.14± 0.05 ClimaticChange , vol. and RSS v3.3 Shah, and E.
Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. But there is more.
of solar correlations in all manner of climate records ( and non-climate records ) has been a staple of the ABC (‘Anything-but-CO 2 ‘) crowd since the 1980s. 4171-4176, 2013. Gundermann, "Solar cycle lengths and climate: A reference revisited", Journal of Geophysical Research: Space Physics , vol. Laut, and J.
Regardless, the company publicly cast doubt on the reality of global warming, attempted to discredit climate scientists and climate models, and tried to block climate action. The new paper in Science summarizes key statements by ExxonMobil executives between 2000 and 2013 that cast doubt on the science.
Land-Use and ClimateChange Growing urban populations are accelerating land-use change (LUC) around the globe, as witnessed in the Front Range of Colorado 1–3. In recent history, we have witnessed LUC exacerbating climatechange due to disturbed soils, development of greenhouse gas (GHG) producing land uses, and more 4.
The hybrid set-up, with video links between the two hubs and digital attendence through zoom, was a change from previous ICRCs held in ICTP (2011) , Brussels (2013) , Stockholm (2016) , and Beijing (2019). They often have set protocols and routines that are not designed to accommodate climatechange adaptation.
As climatechange makes annual wildfire seasons longer and more devastating, predicting when and where these disastrous blazes will spread has become crucial. This makes water vapor rise into the atmosphere, which often generates ‘dry’ thunderstorms, whose rainfall can evaporate before reaching the ground due to extreme heat.
Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climatechange was scant. Don’t mention the hiatus: Readers will probably remember the prominence of the ‘hiatus’ in the discussions around the AR5 report (written in 2013) (see here , here , or here ). Johnson, A.
Likely climatechange impacts in New Zealand | Ministry for the Environment, 2019). The science behind climatechange. Climatechange, according to the Intergovernmental Panel on ClimateChange (IPCC), is the noticeable change in the climate across time (decades or longer).
a joint venture of Shell, Petronas, Mitsubishi, PetroChina and Kogas): 2013 – 2021 Shell Canada Ltd.: 2010 – 2013 Shell Oil Company Inc.: During her tenure on the board it published numerous reports and op-eds that aimed to cast doubt on the seriousness of climatechange. Shell Canada Products Ltd.: million gas cars.
L&D has a specific meaning in climate talks that may not be obvious to anyone not immersed in the process: harms caused by climatechange that are not avoided by adaptation. Given any particular trajectory of realized climatechange (which of course depends on how fast emissions are cut), adaptation measures (e.g.,
On May 21, 2024, the International Tribunal for the Law of the Sea (ITLOS) released its long-awaited advisory opinion on climatechange. There was little discussion, either in the written statements or at the oral hearing, of so-called “marine geoengineering” activities that seek to use the ocean to combat climatechange.
The rotation of the Earth has been affected over the past 25 years by the rapid melting of glaciers caused by climatechange, according to a study done by scientists in China and Denmark. Convection in the mantle is also believed to contribute to this long-term drift. Amazing GRACE.
The number of conventional violations is the largest on record-- at least since 2013. Plugging wells to stop the vertical flow of fluids and gas is critical to preventing ground and surface water contamination and the release of climate-changing methane gas into the atmosphere. Read more here.]
ClimateChange From Science to Solutions. By 2013, the population had decreased from 125,000 to fewer than 10,000 individuals. But one year later, in 2014, the population exploded to about 300,000 green crab in the lagoon — a 30-fold increase over 2013 levels and nearly triple the pre-eradication population size.
However, increasingly frequent and compounding climate-change related events threaten the lives and livelihoods of those communities. Over the course of seven days in November 2021, two atmospheric rivers brought down over 12 inches of rain across the Pacific Northwest. In this current funding cycle, we are administering $64.5
Day 3 was “Finance Day”: how does the world pay for the necessary changes both to reduce emissions (“mitigation”) and to adapt to climatechange (“adaptation”). The chief topic across dozens and dozens of venues was how do less developed countries afford transitions and climate shocks. by Andrew Barton.
On 7 June, before the summer started, the Ministry of Ecology and Environment and 16 other government departments published a 2035 National ClimateChange Adaptation Strategy. This represents the latest guidance on how China will adapt to climatechange. That’s why so few people are doing climate adaptation.”.
When forests burn, that carbon is released into the atmosphere and contributes to greenhouse gases (mostly as carbon dioxide). Forest Ecology and Management 2013 , 294 , 54–61. ClimateChange Presents Increased Potential for Very Large Fires in the Contiguous United States. link] (2) Westerling, A. Hidalgo, H.
In China, cadmium in soil mainly comes from atmospheric deposition of the metal after it has been emitted from coal-burning, metallurgical facilities and animal-source fertilisers. Research has estimated that the soil could keep from the atmosphere the equivalent of 23.8 each year.
That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere. Nearly two-thirds of industrial heat-trapping emissions can be traced to just 90 entities.
A relentless interval of hot, dry weather, made worse by heat-trapping gases in the atmosphere, has turned this section of the state into a cauldron of flame, dust, and smoke. The Intergovernmental Panel on ClimateChange, a group of the world’s leading climate scientists, released its sixth climate assessment on Monday.
Data centers store and share applications and data and are expected to impact freshwater resources through increased water consumption in the face of climatechange. Pennsylvania Sea Grant is supported by the National Oceanic and Atmospheric Administration (NOAA), Penn State University, and through federal, state, and local funding.
With the United Nations ClimateChange Conference (COP26) coming up next month, it is strange to think that less than 100 years ago global warming was not widely accepted, even among experts. The non-expert in question was Guy Callendar , a British steam engineer doing his own atmospheric research at home.
While salmon runs fluctuate from year to year and this year’s returns have been higher than those of the past few years, human-caused climatechange continues to warm the ocean and rivers, and the failure to improve salmon survival rates has left the region’s tribes facing a future without either wild or hatchery fish.
Studies show it may be possible through the adoption of improved farming practices which take carbon dioxide out of the atmosphere and store it in the soil. 5 Changing the way we farm has promise for our fight against climatechange, but what does this mean for our nation’s farmers? References 1 IPCC. link] 4 Abdalla, M.,
Long term, climatechange is a greater threat than the COVID-19 pandemic. As air sunk through the atmosphere, it got squeezed and heated. Without human-induced climatechange, that heat would be at least 150 times rarer. Taken together, however, clouds in today’s atmosphere have an overall net cooling effect.
4] As our climate is warming due to rising emissions of greenhouse gases into our atmosphere, extreme weather events and intense variations in temperature are becoming more frequent. [5]. A cow near flames of the 2013 Rim Fire close to the Yosemite National Park border in Groveland, California. [6] Climate Central.
CarbonBrief specializes in creating clear, data-driven articles and visualizations that help improve the climatechange understanding from the scientific and policy perspectives and help individuals increase their air pollution awareness. Dr. Gabriela Adler - Climate Scientist. Owner of a master’s degree and a Ph.D.
On Friday, December 11th, atmospheric conditions resulted in a catastrophic tornado outbreak that wreaked havoc across America’s Heartland. billion in economic damage , while the 2013 Moore tornado caused an estimated $2 billion in damage as well. million increase to the National Oceanic and Atmospheric Administration’s budget.
Because methane has 28 times the global warming potential of carbon dioxide and a shorter atmospheric life of only 12 years, immediate action to reduce methane emissions —including from agriculture—is critical to slow our warming climate, especially in light of expanding global populations and food demand. 2018 , Petersen et al.,
Testimony before the House Agriculture Committee for a Hearing on “ClimateChange and the U.S. Technological change and agricultural modernization will significantly outweigh climatechange in the U.S. Technological change and agricultural modernization will significantly outweigh climatechange in the U.S.
Among the topics up for discussion was the application of the London Convention and Protocol to certain ocean-based climatechange mitigation activities. In 2013, the parties to the London Protocol adopted an amendment , which sought codify this approach.
