See attached chart, noting in particular the trending of atmospheric CO2 levels by R. A. Berner [2001]. Also note the temperature chart at the top of the above article shows that about 100 million years ago, global atmospheric temperatureswere about 40 deg-F...
The temperature of the plasma in this area increases from about 200,000° to ~ 10 million °. The transition zone directly adjoins the earth’s magnetosphere; the boundary of the magnetosphere, the magnetopause, passes along the line where the dynamic pressure of the solar wind is equalized ...
The chart is compiled from49,868,490 daily readingsof Daily Maximum Temperature (TMAX) from all US reporting stations. With a sample-size of fifty million raw data points, minor corrections from NOAA respected, the claim "temperature is following a normal sine wave" can be stated with high ...
Oceanic anoxic events are geologically abrupt phases of extreme oxygen depletion in the oceans that disrupted marine ecosystems and brought about evolutionary turnover. Typically lasting ~1.5 million years, these events occurred frequently during the Mesozoic era, from about 183 to 85 million years ago...
which resulted in oceans being 138m deeper than the present level 23,000 years ago. This article looks at the cycles that drive the climate trends that create glaciation and interglacials. Chart 1 provides the reconstructed temperature history based onEPICA Dome Cand theSpratt 800kyr sea level ...
An ancient biological survival on Earth 400 million years, they appear as early as the dinosaurs 300 million years ago has existed. They are the ocean's top predator, the sea is well-deserved hegemony, sharks. 翻译结果2复制译文编辑译文朗读译文返回顶部 ...
Bar chart showing the number of Ramsar sites in different ranges of (a) precipitation (mm), (b) elevation (m), (c) maximum temperature, (d) mean temperature, and (e) climate class. This figure is created using Microsoft Excel 365, Version 2308 (https://www.microsoft.com/en-in/microso...
with the Eurasian Plate, and the Himalayas are still rising by about 5 mm per year because the Indo-Australian plate is still moving at 67 mm/year. The history of the Himalayas broadly fits the long-term decrease in Earth’s average temperature since the mid-Eocene, 40 million years ago....
The sixth planet from the sun and the second largest in the solar system, having a sidereal period of revolution about the sun of 29.5 years at a mean distance of about 1.43 billion kilometers (891 million miles), a mean diameter of approximately 121,000 kilometers (75,000 miles), and ...
The remaining 79.4 Gt of the top 75% of irrecoverable carbon could be secured by protecting or sustainably managing an additional 8 million km2, about 5.4% of the planet’s terrestrial surface. Given the concentration of vast sums of irrecoverable carbon within a relatively small land ...
