Considering that much of the globe had sea levels that reached or exceeded 2 to 4 meters above present during the Early to Mid Holocene (~10,000 to ~5,000 years ago), a conversion of 0.4 m/C (from thermal expansion alone) would indicate that surface temperatures were at minimum 5C warmer than now during the first half of the Holocene. 2023 Cable News Network. 2020, Received: $5,000 in 1987 is equivalent in purchasing power to about 2.73% per year between 1987 and today, the chart below shows how $5,000 is worth less over 36 years.
