Share this…FacebookTwitterIt didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer than today, […]

Share this…FacebookTwitterCoastal history analyses increasingly suggest sea levels are lower today than at any time in the last 7000 years – even lower than the 1600s to 1800s. Recently we compared cartology from the 17th to 19th centuries to direct aerial images of coastal positions today. Rather surprisingly, there seemed to be more land area […]

Share this…FacebookTwitterScientists (Bragato and Holzhauser, 2019) find natural catastrophes like tornadoes and earthquakes and pandemics like plague, cholera, and influenza “concentrate in the periods of ice expansion in Europe” whereas periods of economic expansion and a lower incidence of natural catastrophes and pandemics occur during deglaciation phases, or warm periods. Century-scale cooling can be elicited […]

Who would have thought! (sarcasm) Hat-tip: NTZ reader Mary Brown. University of California Irvine researcher Jessica Wang and her team of researchers find plenty of natural climate variability in […]

Share this…FacebookTwitterNewly published macrofossil discoveries from 4 papers strongly suggest that modern warmth may still be about 3°C colder than nearly all of the last 10,000 years. Image Source: Leunda et al. (2018) 1. Permafrost is still present today in a region that was permafrost-free throughout the Holocene (until the onset of the Little Ice Age) […]

Share this…FacebookTwitterEven though CO2 concentrations hovered well below 300 ppm throughout most of the Holocene, newly published paleoclimate reconstructions affirm that today’s surface temperatures are only slightly warmer (if at all) than the coldest periods of the last 10,000 years. This contradicts the perspective that temperatures rise in concert with CO2 concentrations. Bottom Graph Source: Rosenthal et […]

Share this…FacebookTwitterThe purveyors of climate alarm posit that rising CO2 emissions cause up to 600% increases in burned area due to global warming. Newly published science thoroughly undermines these claims. Observational evidence affirms global-scale fire frequencies and burned area have actually been declining for decades (especially since the early 1900s), with overall biomass burning lower today […]

Share this…FacebookTwitterA documentary dubbed “The Weather Machine” produced in 1975 – long before NASA fiddled with the data – warned of an impending ice age (10:35), and maintained that the globe is cooling. Hat-tip: reader The Indomitable Snowman. The documentary attempted and succeeded at presenting the latest on climate change at the time. Changing climate accepted as […]

It has been increasingly established that low solar activity (fewer sunspots) and increased […]

The study region, the Chukchi […]
