I've added a list to some of my favorite (free) sources for weather forecast models and specialized analysis: zacklabe.com/resources-and-…
I've created a new visualization to better compare the dramatic losses of #Arctic sea ice volume at the annual minimum and annual maximum times of year. I'll update this seasonally at: zacklabe.com/arctic-sea-ice….
I've added a new page on my website to help organize the visualizations for tracking various climate change indicators. Some of these figures will be updated monthly (or annually). Again, you can click on each graphic to enlarge/download.
I love looking at vertical cross-sections of climate variables (yes, I probably should get out more). So I decided to add annual trends in zonal-mean temperature and zonal winds to my indicators page: zacklabe.com/climate-change…. Data is from ERA5 in both visuals for 1979-2021.
And here are the corresponding trends in annual mean geopotential heights - will be updated yearly at zacklabe.com/climate-change…. This is consistent with a warming troposphere and cooling stratosphere.
Here's a new page to highlight visualizations of climate seasonality & variability, especially in the #Arctic. This is meant to show our mean climate state and does not focus on recent trends or anomalies. More to come here (e.g., polar vortex, jet)!
Like I've said before, I think it's very important to stress that land temperatures are warming significantly faster than the global average. So, I decided to create a visualization to track this relative to pre-industrial levels.
🧵 While extreme events receive a lot of the attention in the #Arctic, it's more the long-term trends that are transforming this part of the world. Interannual variability (e.g., weather) is also large, which is why not every year is a new record. Here are those January trends:
Nearly all areas of the #Arctic have observed thinning ice over the last four decades. Trends in January are largest in the vicinity of the East Siberian Sea and north of Greenland.
In contrast, sea ice concentration trends in January are only confined to the outer edges of the #Arctic Ocean, such as the Barents-Kara Seas and Sea of Okhotsk.
The annual @NOAA Arctic Report Card is available today for 2021. It discusses recent changes in the #Arctic, extreme events, and broader human/environmental impacts.
@NOAA@NOAAResearch@NOAANCEI@NOAAClimate@CSUAtmosSci "The Arctic story is a human story, and we all have a role to play in creating the best possible outcomes for the region, its residents, and all the citizens of the globe who depend on the Arctic as a critical component of our Earth system." ---> arctic.noaa.gov/Report-Card/Re…
More reading! A thread of peer-reviewed studies evaluating projections of 21st century Arctic sea-ice extent/area/thickness (seasonally ‘ice-free’)... 🧊📉
I am sure I missed a few, so feel free to add.
Note – I am not making any predictions from this thread 😅
Over the last 5 years, there have been plenty of extreme weather/climate events in the #Arctic. While the scientific process takes time, there are now lots of studies investigating these cases. Please add to this thread with other peer-reviewed studies on recent Arctic extremes!
