Full of clear graphs, such as this one on the energy consumption of new cars. Battery electric consumption mode is one third of that of combustion engines.

PHEVs combine the worst of both worlds: higher electric consumption than BEVs and higher fuel consumption than “regular” fossil fuel vehicles.
Energy consumption of different fuel / drivetrain types

As we move into the final days of the year, 2025 has just overtaken 2022 as warmest year-to-date for Central England.

Given the forecast, it looks likely that 2025 will end up being the warmest calendar year for this region since records began in 1659.

The top 3 warmest will be 2022, 2023 & 2025.

When global temperatures shot up by ~6°C about 56 million years ago, plants were unable to thrive

The reduced ability of vegetation & soils to capture & store carbon may have kept temperatures elevated for >100,000 years

Today Earth is warming ~10 times faster than it did 56 million years ago
56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
It could be a sign of what’s to come.

No matter what the relationship is between the football program budget and funding the rest of the university, can't the high-level admins who made these coach buyout deals see how insulting and demoralizing they are for faculty and staff being told their institutions face budget crises?

I reckon (hypothesize) the white ring will be a useful marker ring for your CRN. Wonder if it is the late frost of 2007 (or was it 2008…it predates my phone and the pic I took in KY. Pretty sure it was 2007)

The oblong/oval’ish brown patches?

Reminds me of when an entamogist told me about Thrips impacts on maples. This was down in the Smokies

That white ring is a signal. What year is that?

🌳💧📊 #PhDAlert! MSc in #ForestEcology or #EnvironmentalSciences? Excellent analytical and statistical skills in time-series analysis and experience with #treering methods🪵? We offer a #PhD position in #Dendroecology: apply.refline.ch/273855/1795/... #dendrosciences #ecology #ScienceJobs
Job offer: PhD in Dendroecology (f/m/d) You will be part of a project aiming to empirically disentangle atmospheric vs. soil drought impacts on intra- and inter-annual wood formation, and mechanistically model drought constraints on intra- and inter-annual tree growth dynamics (https://www.wsl.ch/en/projects/sad-tree) based on a unique monitoring network of 44 forest sites in Switzerland spanning 10 years of soil moisture and atmospheric climate data. In this context, you will contribute to the establishment and analysis of intra- and inter-annual time series of tree growth based on dendrometer, tree rings, and quantitative wood anatomy (QWA). You will be responsible for establishing improved empirical relationships of tree growth-environment interactions based on the long-term integrative Soil-Plant-Atmosphere-Continuum dataset (tree & stand traits, physical environment), analyzing: intra-annual water- and growth-related stem radius changes from dendrometer measurements, early-season wood anatomy related to water transport and rehydration, and long-term drought effects on growth using tree-ring widths. You have a Master's degree in forest ecology, environmental sciences, or equivalent. You should have excellent analytical and statistical skills in time-series analysis, preferably in dendrosciences and/or tree physiology. Ideally, you are proficient in programming and handling of large datasets, and have experience with tree-ring methods. You are able to efficiently expand and acquire knowledge in topics relevant to the project. You have a proficient command of written and spoken English, are able to work in a structured, efficient and independent manner, and have a high level of team spirit and have good communication skills.

Picture of book "When Trees Testify" with text that reads: "We have been waiting for this. A botanical memoir, a history, a history with a Black lens-that takes us from roots to branches giving us the keys to an alternative retelling of the American landscape and the ways plants mark who we are and where we've been.
