Rural, low-income communities with high proportions of elderly residents face the most potential exposure to fracking-related contamination in their groundwater, according to a new study. 🧵1/9 news.agu.org/press-release/… 
Over the past two decades, #fracking has boomed in the Appalachian Basin. But so have concerns about contaminated drinking water. 2/9
The @EPA’s latest report on groundwater pollution from fracking was released in 2016, and one of its main conclusions was that we lack good data on how drinking water could be contaminated by fracking.

New from me: I worked with @AGU_Eos, @theAGU + #AGUpubs to put together a plain-language, Q&A-style piece discussing our recent review paper on climate tipping elements!
Thanks to @AGU_Eos for inviting me to write this Editor's Vox article.

The @AGU_Eos editors posed great questions:
- What are tipping elements? Which ones did you review?
- What are challenges of studying tipping elements?
- What is a “tipping cascade”?
- Which tipping elements could start undergoing major changes soon?
- What Qs remain unanswered?

One thing I would emphasize is that climate impacts from tipping elements do not manifest abruptly overnight. Many tipping elements like permafrost soils or ice-sheets act overall on longer timescales of a century or more. Some can show shifts faster, over decades.
Scientists have mapped the biggest cumulative logjam, covering about 20 square miles of a delta high in the Canadian Arctic. And, it turns out, it stores A LOT of #carbon.

Rivers and deltas throughout the #Arctic collect driftwood for hundreds of years. Because it’s so cold, centuries-old trunks are often preserved in pristine condition, indiscernible from a tree that fell a decade ago. news.agu.org/press-release/… 2/10
All those trees are storing carbon, just like their living relatives. And although scientists know these large, woody deposits are all over the Arctic, they don’t know much about how big they actually are. 3/10
Oeh, volgens een studie in #AGUpubs is de magmakamer van Kolumbo, een onderzeese vulkaan in Griekenland, tussen Santorini en Anafi, net zo gezwollen als vlak voor de laatste eruptie in 1650 CE, een VEI 6. Mogelijk Vuurwerk bij de Helleense trog dus. newsweek.com/hidden-magma-c…
Niet iedereen beseft het, maar al die leuke eilanden tussen Griekenland en Turkije maken deel uit van een complex, deels actief eilandboog-trog systeem, omdat de Afrikaanse plaat daar onder de Euraziatische plaat duikt. Het klapt er niet vaak, maar als het klapr, klapt het goed.
De laatste keer dat Santorini klapte was zo heftig, dat de gebeurtenis duizend jaar later in de Bijbel opdook als God zelf. De Vuurkolom Des Nachts en Wolkkolom Des Daags van de Minoïsche eruptie ± 1625 BCE werd overal langs de kusten van de Med. gezien, van Egypte tot Anatolië.
Many journals from @theAGU now display a @scite badge above each article, which claims to quantify how many times subsequent papers 'dispute' and 'support' the article's results.
I'm concerned that the @scite algorithm misidentifies which works are disputed. #AGUpubs 1/

In environmental science, we frequently compare our results with data from another time/place. We perform a literature review of related datasets, and may state that our results "contrast with Zhao et al." @scite often flags this type of phrasing as 'disputing' Zhao's results. 2/
Here's an example:
"However, we have not found any correlation between CH4 and MeHg in surface waters, unlike other studies (ref A), possibly due to CH4 being oxidized in CO2 during its transport from the deep parts of the water column to surface waters (ref B, ref C). " 3/

Summary:
Using a reanalysis to incorporate observations from the past 39 winters, we find a robust dependence of teleconnections from the Madden-Julian Oscillation (MJO) to the North Atlantic/European region weather regimes on the state of the El Niño–Southern Oscillation (ENSO)

Our study provides the first evidence to support this: in the form of contingency tables, using the method and format from @cassouman40, Nature (2008); geopotential height composites, to show the flow pattern; and analysis of the physical mechanisms
