Scientists have captured Earthβs climate over the last 485 million years
A history of wild temperature shifts and offered a warning on the consequences of human-caused warming

(Science) What was Earthβs temperature tens to hundreds of millions of years ago? The planet has gone through different periods, some with extensive polar ice caps and others being completely ice-free. Estimating past global temperature is important for understanding the history of life on Earth, for predicting future climate, and more broadly, to inform the search for other habitable planets. ...
Judd et al. have brought a powerful new tool to this task: data assimilation. They combined a large set of climate model simulations at different global temperatures across the last 485 million years with the oxygen isotope dataset as well as with other less frequently sampled temperature indicators such as temperature-sensitive organic molecules. Joining the model and the geological data enabled the authors to account for regional variations in predicted temperature. For example, a sample from a polar region was compared to climate model predictions in the same region. This produces a more accurate estimate of the global average temperature of Earth over time.

{WaPo) An ambitious effort to understand the Earthβs climate over the past 485 million years has revealed a history of wild shifts and far hotter temperatures than scientists previously realized β offering a reminder of how much change the planet has already endured and a warning about the unprecedented rate of warming caused by humans.
The timeline, published Thursday in the journal Science, is the most rigorous reconstruction of Earthβs past temperatures ever produced, the authors say. Created by combining more than 150,000 pieces of fossil evidence with state-of-the-art climate models, it shows the intimate link between carbon dioxide and global temperatures and reveals that the world was in a much warmer state for most of the history of complex animal life.
At its hottest, the study suggests, the Earthβs average temperature reached 96.8 degrees Fahrenheit (36 degrees Celsius)... The revelations about Earthβs scorching past are further reason for concern about modern climate change, said Emily Judd, a researcher at University of Arizona and the Smithsonian specializing in ancient climates and the lead author of the study. The timeline illustrates how swift and dramatic temperature shifts were associated with many of the worldβs worst moments β including a mass extinction that wiped out roughly 90 percent of all species and the asteroid strike that killed the dinosaurs.
βWe know that these catastrophic events β¦ shift the landscape of what life looks like,β Judd said. βWhen the environment warms that fast, animals and plants canβt keep pace with it.β
At no point in the nearly half-billion years that Judd and her colleagues analyzed did the Earth change as fast as it is changing now, she added: βIn the same way as a massive asteroid hitting the Earth, what weβre doing now is unprecedented.β

GreenPolicy360:
When climate change came 'on the radar'
GreenPolicy360 journeys across 50+ years of the modern environmental movement
This story is now 50 years plus old and at GreenPolicy360 we have been attempting to bring to light many of the salient, and key moments of the history and crucial-to-know events that have led to today's activism dealing with climate change. The origins of earth science, atmospheric science, the environmental protection movement, the technology to measure and monitor earth system and dynamic change have brought us to today.
Thank you for visiting us and please feel free to click through our content and links. We are an open-source MediaWiki platform after all and our originating model was to share 'green best practices' worldwide. Climate change and climate policy, realization of the problems bring us to climate action.
Environmental protection with green activism/politics/education is a story that has gone on over decades, from the 1960s on. With GreenPolicy360 we look back to joining in ... involved directlyn with the first Earth Day (via Senator Gaylord Nelson and Representative George Brown in the envisiong, planning and organizing) and with Earth System Science initiatives, especially to collect data through new NASA and NOAA programs, to identify the extent of climate change.

The First National Climate Act, Historic Work
GreenPolicy360 Siterunner / SJ Schmidt: The beginnings of modern environmental and climate science can be traced to the 1960s and 1970s. The U.S. National Academy of Sciences played a key role in laying a foundation of scientific reports and data.
Energy and Climate Report, 1977, National Academy of Sciences / 175 pp. / PDF via GreenPolicy360
Rep. George Brown took the findings of the 1977 Energy and Climate Report from the Academy of Sciences and made the science actionable. In a historic moment, he proposed and drafted the legislation of the first U.S. National Climate Program and shepherded its passage in 1978.
This first federal program established to study and assess scientifically the issues and risks of human-caused climate change became a foundation for comprehensive initiatives, with an array of new Earth Science missions led by NASA and NOAA, the EPA and USGS.

It's no ride in the park looking back at some 50+ years of environmental protection work. The obstacles were many, the climate change denial purposeful, and the dis- and mis-information pervasive. Those of us who were developing the field of climate science were, although we didn't describe it as such, creating a story arc of the climate change movement. The genesis of climate science was becoming a key 'atmospheric science' question to Congressman George E. Brown in the 1960s and I was, as a high school student, becoming a political follower of my representative's work. George went on to be a 'mover and shaker' in Congress and leader, as a trained physicist and practicing engineer, in the science and policy of climate. His work is essential in understanding how climate change powered up a constellation of NASA/NOAA/USGS programs and missions, many of which were the first of their type gathering digital data and earth science imaging. I was fortunate, as an environmental activist, to be along for the ride over the years until George's untimely passing in 1999.
Thank you George for all you did, the perseverance, the vision, the hard work. You made a world of difference, a positive difference that goes on and on (and you changed my life) -- https://www.greenpolicy360.net/w/Earth_Day_Memories_on_the_50th_Anniversary
To our GreenPolicy360 readers, please take a look, a close look, at George E. Brown as I've recalled many of his contributions here -- https://www.greenpolicy360.net/w/George_E._Brown_Jr
Let us also all take a look at some of the history of climate conferences over the years here -- https://www.greenpolicy360.net/w/File:Climate_Conferences_1979-2020.jpg
The work continues as we step up and do our best, becoming Planet Citizens day-by-day, month-by-month, year-by-year, decade-by-decade.

Climate Change Forecasts and Hindcasts: How Accurate Have Predictions Been of Climate Scientists?
Study Confirms Climate Models are Getting Future Warming Projections Right
NASA Science Editorial Team
JAN 09, 2020
An animation of a GISS (Goddard Institute for Space Studies) climate model simulation made for the United Nations' Intergovernmental Panel on Climate Change Fourth Assessment Report, showing five-year averaged surface air temperature anomalies in degrees Celsius from 1880 to 2100. The temperature anomaly is a measure of how much warmer or colder it is at a particular place and time than the long-term mean temperature, defined as the average temperature over the 30-year base period from 1951 to 1980. Blue areas represent cool areas and yellow and red areas represent warmer areas. The number in the upper right corner represents the global mean anomaly.
NASAβs Goddard Institute for Space Studies
Thereβs an old saying that βthe proof is in the pudding,β meaning that you can only truly gauge the quality of something once itβs been put to a test. Such is the case with climate models: mathematical computer simulations of the various factors that interact to affect Earthβs climate, such as our atmosphere, ocean, ice, land surface and the Sun.
For decades, people have legitimately wondered how well climate models perform in predicting future climate conditions. Based on solid physics and the best understanding of the Earth system available, they skillfully reproduce observed data. Nevertheless, they have a wide response to increasing carbon dioxide levels, and many uncertainties remain in the details. The hallmark of good science, however, is the ability to make testable predictions, and climate models have been making predictions since the 1970s. How reliable have they been?
Now a new evaluation of global climate models used to project Earthβs future global average surface temperatures over the past half-century answers that question: most of the models have been quite accurate.
Forecast_evaluation_for_models_run_in_2004_in_F_and_C
Models that were used in the IPCC 4th Assessment Report can be evaluated by comparing their approximately 20-year predictions with what actually happened. In this figure, the multi-model ensemble and the average of all the models are plotted alongside the NASA Goddard Institute for Space Studies (GISS) Surface Temperature Index (GISTEMP). Climate drivers were known for the βhindcastβ period (before 2000) and forecast for the period beyond. The temperatures (in degrees Fahrenheit on the left and degrees Celsius on the right) are plotted with respect to a 1980-1999 baseline.
-- Gavin Schmidt
In a study accepted for publication in the journal Geophysical Research Letters, a research team led by Zeke Hausfather of the University of California, Berkeley, conducted a systematic evaluation of the performance of past climate models. The team compared 17 increasingly sophisticated model projections of global average temperature developed between 1970 and 2007, including some originally developed by NASA, with actual changes in global temperature observed through the end of 2017. The observational temperature data came from multiple sources, including NASAβs Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP) time series, an estimate of global surface temperature change.
The results: 10 of the model projections closely matched observations. Moreover, after accounting for differences between modeled and actual changes in atmospheric carbon dioxide and other factors that drive climate, the number increased to 14. The authors found no evidence that the climate models evaluated either systematically overestimated or underestimated warming over the period of their projections.
βThe results of this study of past climate models bolster scientistsβ confidence that both they as well as todayβs more advanced climate models are skillfully projecting global warming,β said study co-author Gavin Schmidt, director of NASAβs Goddard Institute of Space Studies in New York. βThis research could help resolve public confusion around the performance of past climate modeling efforts.β

Climate Impact of Increasing Atmospheric Carbon Dioxide
From the Journal of Science
28 August 1981, Volume 213, Number 4511
James Hansen et al.
Greenhouse Effect
Atmospheric CO2 increased from 280 to 300 parts per million in 1880 to 335 to 340 ppm in 1980, mainly due to burning of fossil fuels....
Summary. The global temperature rose by 0.20C between the middle 1960βs and1980, yielding a warming of 0.4Β°C in the past century. This temperature increase is consistent with the calculated greenhouse effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980βs. Potential effects on climate in the 21st century include the creation of drought-prone regions in North America and central Asia as part of a shifting of climatic zones, erosion of the West Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the fabled Northwest Passage.
