Global Warming Science, When Did the Science on Climate Change Start, an Introduction by GreenPolicy360's founder:

In the mid-1960s, a man who was trained in science and physics, and who was an engineer who became a politician in East Los Angeles, California, explained to me that the health impacts of LA's smog were dire, especially for children. Pollution, emissions into the lower atmosphere, were severe and consequences on health were more than evident, they were an epidemic that had turned the LA basin into a pollution/smog 'capital of the world'.

The newly elected Congressman went on to explain the air quality was not just a local problem that needed to be 'fixed', but that the larger questions of industrial pollution needed to be addressed. He said we needed science, a major scientific mobilization to provide the atmospheric science and the data needed. George Brown spoke of solutions to the problems of pollution. He spoke of health and life.

Representative Brown and I became friends, then colleagues in our work over decades. Our paths and politics intertwined and our stories, which I am venturing to tell here at GreenPolicy360, reveal elements of a green first generation, an environmental movement in action.

George Brown played historic roles in advancing Earth science, climate change science, atmospheric science and Earth system. He became a leader, a mover and shaker in Congress from the 1960s thru the 1990s. He envisioned, coordinated and, as a member/chair of Earth science, space and technology committee work, acted created the first national climate plan, the EPA, a slate of foundational environmental law, and a constellation of NASA missions, including Landsat, that are still providing critical data to this day. The Earth Observing System, the Earth Information Center, a vast array of programs and projects measuring/monitoring Earth systems continuing are a legacy of a special person, George E Brown, who passed away in Washington DC in 1999.

He was looking forward to the 21st Century....

Let's start a Global Warming and Climate Change page here with George's life and work.

Global Warming, an Update with CERESMIP

Climate modeling protocol to investigate 'Earth's Energy Imbalance' (global warming)

July 2023

The Earth's Energy Imbalance (EEI) refers to an imbalance between how much solar radiant energy is absorbed by Earth and how much thermal infrared radiation is emitted to space (Stephens et al., 2012; Trenberth and Cheng, 2022; von Schuckmann et al., 2023). Assuming constant atmospheric composition, a positive EEI would imply increasing global mean temperature, sea level rise, further heating within the ocean and land, and melting of snow and sea ice (Masson-Delmotte et al., 2021). As such, EEI is a key metric for detecting ongoing anthropogenic climate change and assessing the causes (e.g., Hansen et al., 1988, 2005). Climate models have long predicted that the increases in well-mixed greenhouse gases would cause an increasing net energy imbalance for the planet, a prediction that was borne out with the observed increases in ocean heat content (e.g., Levitus et al., 2001; Meehl et al., 2005; Donohoe et al., 2014; von Schuckmann et al., 2016; Hakuba et al., 2021; Cheng et al., 2022). Over the period 1970-2020, the EEI is estimated to have been 0.48 ± 0.1W m−2 (von Schuckmann et al., 2023), with a clear acceleration seen over the last two decades.

US 'Big Science', Global Environmental & Climate Change, Vision, Mission, and Strategic Planning

Steve Schmidt/SJS: With memories of the Big Science vision of Rep. George E. Brown with his goal of studying and understanding "our changing planet"

The U.S. Global Change Research Program (USGCRP) is a federal program mandated by Congress to coordinate federal research and investments in understanding the forces shaping the global environment, both human and natural, and their impacts on society. USGCRP facilitates collaboration and cooperation across its 14 federal member agencies to advance understanding of the changing Earth system and maximize efficiencies in federal global change research.

Together, USGCRP and its member agencies provide a gateway to authoritative science, tools, and resources to help people and organizations across the country manage risks and respond to changing environmental conditions.

Earth Science Vital Signs

A century-scale rise in average temperature of the Earth's climate system, the global, escalating effects & environmental impacts

Multiple lines of scientific evidence show that the climate system is warming. Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into ocean warming. The remainder has melted ice and warmed the continents and atmosphere.

Looking to the beginnings of U.S. study and action on climate change and global warming. Congressman George E. Brown, who goes on to become chair of the House Science & Technology Committee in a thirty year Congressional career, authors a historic climate action initiative...

Energy and Climate Report, 1977, National Academy of Sciences / 175 pp. / PDF via GreenPolicy360

In the decade after the original Energy and Climate Report and the first National Climate Program Act start up, a Reagan-era challenges government earth science missions. The Landsat mission is threatened by presidential budget with elimination. Congressman Brown acts to save Landsat's whole earth observation as a central dynamic data resource.

George E. Brown Jr

Congressman Brown from California, a trained physicist/engineer and his team (including the current GreenPolicy360 siterunner) push for more earth science missions and data on which to base forward-looking, progressive policy decisions..

Ten years after the the National Climate Program Act was drafted by Representative Brown that officially began the federal government's study and action on global warming / climate change, its impacts and risks, a scientists's testimony before the US Senate sent news headlines across the media.

What we’re doing to the Earth has no parallel in 66 million years, scientists say

"If you dig deep enough into the Earth’s climate change archives, you hear about the Palaeocene-Eocene Thermal Maximum, or PETM. And then you get scared.

"This is a time period, about 56 million years ago, when something mysterious happened — there are many ideas as to what — that suddenly caused concentrations of carbon dioxide in the atmosphere to spike, far higher than they are right now. The planet proceeded to warm rapidly, at least in geologic terms, and major die-offs of some marine organisms followed due to strong acidification of the oceans...."
