New Temperature Records for the UK

"Abstract The Medieval Climate Anomaly (MCA) is a well-recognized climate perturbation in many parts of the world, with a core period of 1000–1200 CE. Here we are mapping the MCA across the Antarctic region based on the analysis of published palaeotemperature proxy data from 60 sites. In addition to the conventionally used ice core data, we are integrating temperature proxy records from marine and terrestrial sediment cores as well as radiocarbon ages of glacier moraines and elephant seal colonies. A generally warm MCA compared to the subsequent Little Ice Age (LIA) was found for the Subantarctic Islands south of the Antarctic Convergence, the Antarctic Peninsula, Victoria Land and central West Antarctica. A somewhat less clear MCA warm signal was detected for the majority of East Antarctica. MCA cooling occurred in the Ross Ice Shelf region, and probably in the Weddell Sea and on Filchner-Ronne Ice Shelf. Spatial distribution of MCA cooling and warming follows modern dipole patterns, as reflected by areas of opposing temperature trends. Main drivers of the multi-centennial scale climate variability appear to be the Southern Annular Mode (SAM) and El Niño-Southern Oscillation (ENSO) which are linked to solar activity changes by nonlinear dynamics." https://www.sciencedirect.com/science/article/abs/pii/S00310...

And looking back at previous warm periods it looks like things mostly got better during warm ages and nose dived during the cold. https://imgr.search.brave.com/v3hRyzU6Mm1ShpkX2Z4SEYasQRtDD-...

[0] Global Greening

Greening of the globe and its drivers - Nature 2016 https://www.nature.com/articles/nclimate3004 "Satellite records from 1982–2009 show a persistent and widespread increase of leaf area (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing leaf area (browning). Ecosystem models suggest that CO2 fertilisation effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (4%)."

Elevated CO2 as a driver of global dryland greening - Nature 2016 https://www.nature.com/articles/srep20716 "Recent regional scale analyses using satellite based vegetation indices such as the Normalized Difference Vegetation Index (NDVI), have found extensive areas of “greening” in dryland areas of the Mediterranean, the Sahel, the Middle East and Northern China, as well as greening trends in Mongolia and South America. More recently, a global synthesis from 1982-2007 showed an overall “greening-up” trend over the Sahel belt, Mediterranean basin, China-Mongolia region and the drylands of South America."

Global Greening Is Firm, Drivers Are Mixed - Harvard 2014 http://adsabs.harvard.edu/abs/2015AGUFM.B31A0515K "Evidence for global greening is converging, asserting an increase in CO2 uptake and biomass of the terrestrial biosphere. Global greening refers to global net increases in the area of green canopy, stocks of carbon, and the duration of the growing season. The growing seasons in general have prolonged while the stock of biomass carbon has increased and the rate of deforestation has decelerated. Evidence for these trends comes from firm empirical data obtained through atmospheric CO2 observations, remote sensing, forest inventories and land use statistics."

Rise in CO2 has 'greened Planet Earth' http://www.bbc.co.uk/news/science-environment-36130346 Prof Judith Curry, the former chair of Earth and atmospheric sciences at the Georgia Institute of Technology, added: "It is inappropriate to dismiss the arguments of the so-called contrarians, since their disagreement with the consensus reflects conflicts of values and a preference for the empirical (i.e. what has been observed) versus the hypothetical (i.e. what is projected from climate models)
