Climate Change – Uncertainty increasing risk
Biosphere Integrity – off the charts – crossed the planetary boundary
Genetic diversity – we are losing species on this planet mostly on ocean – it’s directly impact our food chain.
We are in 6th mass extinction
Land system change – we are moving in the direction of concern
Fresh water competative to 1950s & 60s it’s improving
Biochemical flows – Nitrogen and Phosphorus from Agriculture – from fertilizers is flowing towards water bodies
Ocean acidification effect Biosphere Integrity
Atmospheric aerosol loading – associated with pollution both manmade and natural pollution like volcanoes 🌋
Stratospheric ozone depletion – disappearing ozone back in 1970s due to human activity
Novel Entities – human caused reasons for problems in our
Understanding Climate Change through Ice Cores Library
Through Greenland Ice Caps and Antarctica
Ice Cores captures little bubbles of air from the atmosphere through that we can know how much CO2 was in the atmosphere for that year, how much oxygen we can know about Volcanoes because of volcanoes 🌋 dust pollen grains, through jet streem we can know the temperature 🌡️ hot or cold, we can know the sea levels 🎚️ too.

Eight glacial cycles from an Antarctic ice core

Climate and atmospheric history of the past 420,000 years from the Vostok ice core, Antarctica
The recent completion of drilling at Vostok station in East Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Interglacial periods differed in temporal evolution and duration. Atmospheric concentrations of carbon dioxide and methane correlate well with Antarctic air-temperature throughout the record. Present-day atmospheric burdens of these two important greenhouse gases seem to have been unprecedented during the past 420,000 years.

When going from interglacial to glacial conditions the change in CO2 concentration actually lags the change in air temperature 🌡️
What causes The warming / cooling of earth
According to the Mathematician Militant Melanchovic – Melancholic Cycles
Earth relationship with Sun
Pre-session of the equinoxes is 24K to 26K yrs of cycles of time
Eccentricity is a range from 100K yrs to 413K yrs cycles
Obliquity this is a 41k yrs cycles tilts.
Milankovitch Cycles and Glaciation
The episodic nature of the Earth’s glacial and interglacial periods within the present Ice Age (the last couple of million years) have been caused primarily by cyclical changes in the Earth’s circumnavigation of the Sun. Variations in the Earth’s eccentricity, axial tilt, and precession comprise the three dominant cycles, collectively known as the Milankovitch Cycles for Milutin Milankovitch, the Serbian astronomer and mathematician who is generally credited with calculating their magnitude. Taken in unison, variations in these three cycles creates alterations in the seasonality of solar radiation reaching the Earth’s surface. These times of increased or decreased solar radiation directly influence the Earth’s climate system, thus impacting the advance and retreat of Earth’s glaciers.
It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables is not due to the total amount of solar energy reaching Earth. The three Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.
Global warming: Why you should not worry

Spencer Michels interviews one of the nations’s most read climate skeptics Anthony Watts a Meteorologist. Watts believes much of the data used to support global warming theories is faulty. The big problem, as Watts sees it, is that the station were temperatures 🌡️ are gathered are too close to urban developments where heat is soaked up and distorts the reading. So it looks like the earth is warming thought it may not be.

Author Thomas Sowell argues that public demand for intellectuals is largely manufactured by intellectuals themselves. He says intellectuals make alarming predictions using causes like global warming to create a needs for their services.

Climate 🔭 scientist Dr. Michael Mann notes climatologist Dr. John R. Christy as a compelling voice on the other side of the climate change debate. Dr. Christy, a pioneer in measuring global temperatures by satellite, 🛰️📡 discusses challenges to understanding data from satellites, balloons, and terrestrial weather stations. He also examines the impact of CO2 and the practical problem with climate models driving energy policy worldwide, especially in developing nations.
Distinguished professor of Atmospheric Science and director of the Earth System Science Center at The University of Alabama in Huntsville, as well as the Alabama State climatologist, Dr. Christy talks with Dr. Jed Macosko, academic director of academicinfluence.com and professor of physics at Wake Forest University.
