Sea Levels Near B.C. Canada Were 90 Meters Higher Than Today 14,500 Years Ago

by K. Richard, Aug 23, 2021 in NoTricksZone

A new study suggests British Columbia (Canada) relative sea levels remained 10 meters higher than they are today until they fell to their present levels in the last ~1800 years. Two other new studies suggest sea levels were still 0.8 to 1 meter higher than today during the Medieval Warm Period.

After the peak of the last glacial about 20,000 years ago, relative sea levels subsequently rose from 120 meters below modern sea levels to heights of 90 meters above today’s by ~14,500 years ago in the Douglas Channel near British Columbia, Canada (Letham et al., 2021).

Sea levels proceeded to fall 75 to 80 meters over the next 3000 years, or about -2.5 meters per century (-25 mm/yr), and then they remained 10-15 m above present for the next ~9000 years.

“We determine that central Douglas Channel was ice-free following the Last Glacial Maximum by ∼14,500 BP and RSL was at least 90 m higher than today. Isostatic rebound caused RSL to fall to 21 m asl by 11,500 BP, though there may have been a glacial re-advance that would have paused RSL fall around the beginning of the Younger Dryas. RSL fell to 10–15 m asl by 10,000 BP, and continued to drop at a slower rate towards its current position, which it reached by ∼1800 years ago.”

NEW STUDY: 23 EXPERTS IN THE FIELDS OF SOLAR PHYSICS AND CLIMATE SCIENCE CONTRADICT THE IPCC — THE SCIENCE IS NOT SETTLED

by Cap Allon, Aug 16, 2021 in Electroverse

A diverse expert panel of global scientists finds blaming climate change mostly on greenhouse gas emissions was premature. Their findings contradict the UN IPCC’s conclusion, which the study shows, is grounded in narrow and incomplete data about the Sun’s total solar irradiance (TSI).

A new scientific review article has just been published on the role of the Sun in climate change over the last 150 years.

It finds that the United Nations’ Intergovernmental Panel on Climate Change (IPCC) may have been premature in their conclusion that recent climate change is mostly caused by human greenhouse gas emissions.

The paper by 23 experts in the fields of solar physics and of climate science from 14 different countries is published in the peer-reviewed journal Research in Astronomy and Astrophysics (RAA).

The paper, which is the most comprehensive to date, carries out an analysis of the 16 most prominent published solar output datasets, including those used by the IPCC.

The researchers compared them to 26 different estimates of Northern Hemisphere temperature trends since the 19th century (sorted into five categories), including the datasets used by the IPCC.

They focused on the Northern Hemisphere since the available data for the early 20th century and earlier is much more limited for the Southern Hemisphere, but their results can be generalized for global temperatures.

Dr. Ronan Connolly, lead author of the study, at the Center for Environmental Research and Earth Sciences (CERES):

“The IPCC is mandated to find a consensus on the causes of climate change. I understand the political usefulness of having a consensus view in that it makes things easier for politicians. However, science doesn’t work by consensus. In fact, science thrives best when scientists are allowed to disagree with each other and to investigate the various reasons for disagreement. I fear that by effectively only considering the datasets and studies that support their chosen narrative, the IPCC have seriously hampered scientific progress into genuinely understanding the causes of recent and future climate change. I am particularly disturbed by their inability to satisfactorily explain the rural temperature trends.”
