“Declaration of Conscience” by Margaret Chase Smith June 1, 1950

Mr. President, I would like to speak briefly and simply about a serious national condition. It is a national feeling of fear and frustration that could result in national suicide and the end of everything that we Americans hold dear. It is a condition that comes from the lack of effective leadership either in the legislative branch or the executive branch of our government…

… I speak as a Republican. I speak as a woman. I speak as a United States senator. I speak as an American…

… I think that it is high time for the United States Senate and its members to do some real soul searching and to weigh our consciences as to the manner in which we are performing our duty to the people of America and the manner in which we are using or abusing our individual powers and privileges.

I think that it is high time that we remembered that we have sworn to uphold and defend the Constitution. I think that it is high time that we remembered that the Constitution, as amended, speaks not only of the freedom of speech, but also of trial by jury instead of trial by accusation.

Whether it is a criminal prosecution in court or a character prosecution in the Senate, there is little practical distinction when the life of a person has been ruined.

“The Basic Principles of Americanism”

Those of use who shout the loudest about Americanism in making character assassinations are all too frequently those who, by our own words and acts, ignore some of the basic principles of Americanism C

The right to criticize.

The right to hold unpopular beliefs.

The right to protest.

The right of independent thought.

The exercise of these rights should not cost one single American citizen his reputation or his right to a livelihood nor should he be in danger of losing his reputation or livelihood merely because he happens to know someone who holds unpopular beliefs. Who of us does not? Otherwise none of us could call our souls our own. Otherwise thought control would have set in.

The American people are sick and tired of being afraid to speak their minds lest they be politically smeared as “Communists” or “Fascists” by their opponents. Freedom of speech is not what it used to be in America. It has been so abused by some that it is not exercised by others.

The American people are sick and tired of seeing innocent people smeared and guilty people whitewashed. But there have been enough proved cases…to cause nationwide distrust and strong suspicion that there may be something to the unproved, sensational accusations.

A Challenge to the Republican Party

As a Republican, I say to my colleagues on this side of the aisle that the Republican Party faces a challenge today that is not unlike the challenge that it faced back in Lincoln’s day. The Republican Party so successfully met that challenge that it emerged from the Civil War as the champion of a united nation C in addition to being a party that unrelentingly fought loose spending and loose programs….

The Democratic administration has greatly lost the confidence of the American people by its complacency to the threat of communism here at home and the leak of vital secrets to Russia through key officials of the Democratic administration. There are enough proved cases to make this point without diluting our criticism with unproved charges.

Surely these are sufficient reasons to make it clear to the American people that it is time for a change and that a Republican victory is necessary to the security of this country…. Yet to displace it with a Republican regime embracing a philosophy that lacks political integrity or intellectual honesty would prove equally disastrous to this Nation. The nation sorely needs a Republican victory. But I do not want to see the Republican party ride to political victory… [using] fear, ignorance, bigotry, and smear… I do not want to see the Republican party win that way. While it might be a fleeting victory for the Republican party, it would be a more lasting defeat for the American people. Surely it would ultimately be suicide for the Republican party and the two-party system that has protected our American liberties from the dictatorship of a one-party system.

As members of the minority party, we do not have the primary authority to formulate the policy of our government. But we do have the responsibility of rendering constructive criticism, of clarifying issues, of allaying fears by acting as responsible citizens.

As a woman, I wonder how the mothers, wives, sisters, and daughters feel about the way in which members of their families have been politically mangled in Senate debate – and I use the word “debate” advisedly…

I do not like the way the Senate has been made a rendezvous for vilification, for selfish political gain at the sacrifice of individual reputations and national unity. I am not proud of the way we smear outsiders from the floor of the Senate and hide behind the cloak of congressional immunity and still place ourselves beyond criticism on the floor of the Senate.

As an American, I am shocked at the way Republicans and Democrates alike are playing directly into the Communist design of “confuse, divide, and conquer.” As an American, I don’t want a Democratic administration “whitewash” or “cover-up” any more than I want a Republican smear or witch hunt.

As an American, I condemn a Republican Fascist just as much as I condemn a Democrat Communist. I condemn a Democrat Fascist just as much as I condemn a Republican Communist. They are equally dangerous to you and me and to our country. As an American, I want to see our nation recapture the strength and unity it once had when we fought the enemy instead of ourselves.

It is with these thoughts that I have drafted what I call a Declaration of Conscience. I am gratified that the senator from New Hampshire, the senator from Vermont, the senator from Oregon, the senator from New York, the senator from Minnesota and the senator from New Jersey have concurred in that declaration and have authorized me to announce their concurrence.

Passage 1

Critical information needed in fight to save wildlife

With global temperatures rising, an international group of 22 top biologists is calling for a coordinated effort to gather important species information that is urgently needed to improve predictions for the impact of climate change on future biodiversity. Current predictions fail to account for important biological factors like species competition and movement that can have a profound influence on whether a plant or animal survives changes to its environment, the scientists say in the September 9 issue of the journal Science. While more sophisticated forecasting models exist, much of the detailed species information that is needed to improve predictions is lacking.

“Right now, we’re treating a mouse the same way as an elephant or a fish or a tree. Yet we know that those are all very different organisms and they are going to respond to their environment in different ways,” says University of Connecticut Ecologist Mark Urban, the Science article’s lead author. “We need to pull on our boots, grab our binoculars, and go back into the field to gather more detailed information if we are going to make realistic predictions.”

The 22 top biologists affiliated with the article identify six key types of biological information, including life history, physiology, genetic variation, species interactions, and dispersal, that will significantly improve prediction outcomes for individual species. Obtaining that information will not only help the scientific community better identify the most at-risk populations and ecosystems, the scientists say, it will also allow for a more targeted distribution of resources as global temperatures continue to rise at a record rate.

Current climate change predictions for biodiversity draw on broad statistical correlations and can vary widely, making it difficult for policymakers and others to respond accordingly. Many of those predictions tend not to hold up over time if they fail to account for the full range of biological factors that can influence an organism’s survival rate: species demographics, competition from other organisms, species mobility, and the capacity to adapt and evolve.

“We haven’t been able to sufficiently determine what species composition future ecosystems will have, and how their functions and services for mankind will change,” says co-author Dr. Karin Johst of the Helmholtz Centre for Environmental Research and the German Centre for Integrative Biodiversity Research. “This is because current ecological models often do not include important biological processes and mechanisms: so far only 23 percent of the reviewed studies have taken into account biological mechanisms. ”

Generating more accurate predictions is essential for global conservation efforts. Many species are already moving to higher ground or toward the poles to seek cooler temperatures as global temperatures rise. But the capacity of different organisms to survive varies greatly. Some species of frog, for instance, can traverse their terrain for miles to remain in a habitable environment. Other species, such as some types of salamander, are less mobile and capable of moving only a few meters over generations.

“New Zealand’s strong foundation in ecological research will help,” explains study co-author Dr. William Godsoe, a Lincoln University lecturer and member of New Zealand’s Bio-Protection Research Centre. “One of our hopes is to build on these strengths and highlight new opportunities to improve predictions by explicitly considering evolution, interactions among species, and dispersal.” This will aid in the development of strategies to manage impacts on species and ecosystems before they become critical.

With more than 8.7 million species worldwide, gathering the necessary biological information to improve predictions is a daunting task. Even a sampling of key species would be beneficial, the authors say, as the more sophisticated models will allow scientists to extrapolate their predictions and apply them to multiple species with similar traits.

The researchers are calling for the launch of a global campaign to be spearheaded by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services or IPBES. The IPBES operates under the auspices of four United Nations entities and is dedicated to providing scientific information to policymakers worldwide. One thousand scientists from all over the world currently contribute to the work of IPBES on a voluntary basis. The scientists are also encouraging conservation strategies to support biodiversity such as maintaining dispersal corridors, and preserving existing natural habitats and genetic diversity.

“Our biggest challenge is pinpointing which species to concentrate on and which regions we need to allocate resources,” says UConn Associate Professor Urban. In an earlier study in Science, Urban predicted that as many as one in six species internationally could be wiped out by climate change. “We are at a triage stage at this point. We have limited resources and patients lined up at the door.”

Passage 2

Forecasting climate change’s effects on biodiversity hindered by lack of data

An international group of biologists is calling for data collection on a global scale to improve forecasts of how climate change affects animals and plants. Accurate model predictions can greatly aid efforts to protect biodiversity from disturbances such as climate change and urban sprawl by helping scientists and decision-makers better understand, anticipate and respond to threats that imperil species and ecosystems.

In a paper published in Science on Thursday (Sept. 8), biologists cite a critical lack of data on key biological mechanisms C such as how animals and plants spread during their lifetime and how they evolve in response to changes in the environment – as the main obstacle to improving models’ ability to forecast species’ response to climate change.

“This paper is a call to arms,” said Patrick Zollner, article co-author and Purdue associate professor of wildlife science. “The world is in dire circumstances. We’re losing a lot of species, and we’re largely unaware why. How do we need to rethink the kind of data we’re collecting so we can take advantage of modern modeling tools to understand the outcomes of climate change for ecological systems? This could help us forestall losing wildlife that we later deeply regret.”

The group outlines two key problems that hinder the capability of current models to make realistic predictions about biological responses to climate change.

Most models are descriptive, based on statistical correlations and observations, and fail to capture the underlying processes that produce observed changes. For example, a descriptive model might show that lynx in the northern U.S. are declining while bobcat populations in the same region are on the rise. Understanding what is driving this change requires a different sort of model, one that incorporates biological mechanisms. A mechanistic model that accounts for how warming temperatures affect snow depth, for instance, could provide insights into why bobcats C better adapted to habitats with less snow – are gaining a competitive edge over lynx. But 77 percent of current models of climate change’s impacts on wildlife do not include biological mechanisms.

Another challenge is that as models have grown in sophistication, they have far outpaced data collection. Put another way, a model is like a state-of-the-art kitchen, but the cupboards are bare.

“We can now build videogame-like environments with computers where we can create multiple versions of Earth and ask what the implications under different scenarios are,” Zollner said. “But our ability to learn from these tools is constrained by the kinds of data we have.”

The group advanced several proposals on how to improve models, collect missing data and leverage available data to make broader predictions.

They identified six biological mechanisms that influence wildlife’s responses to climate change: physiology; demography and life history; evolutionary potential and adaptation; interactions between species; movement over land or water; and responses to changes in the environment.

Passage 1

Critical information needed in fight to save wildlife

With global temperatures rising, an international group of 22 top biologists is calling for a coordinated effort to gather important species information that is urgently needed to improve predictions for the impact of climate change on future biodiversity. Current predictions fail to account for important biological factors like species competition and movement that can have a profound influence on whether a plant or animal survives changes to its environment, the scientists say in the September 9 issue of the journal Science . While more sophisticated forecasting models exist, much of the detailed species information that is needed to improve predictions is lacking.

“Right now, we’re treating a mouse the same way as an elephant or a fish or a tree. Yet we know that those are all very different organisms and they are going to respond to their environment in different ways,” says University of Connecticut Ecologist Mark Urban, the  Science article’s lead author. “We need to

pull on our boots, grab our binoculars, and go back into the field to gather

more detailed information if we are going to make realistic predictions.”

The 22 top biologists affiliated with the article identify six key types of biological information, including life history, physiology, genetic variation, species interactions, and dispersal, that will significantly improve prediction outcomes for individual species. Obtaining that information will not only help the scientific community better identify the most at-risk populations and ecosystems, the scientists say, it will also allow for a more targeted distribution of resources as global temperatures continue to rise at a record rate.

Current climate change predictions for biodiversity draw on broad statistical correlations and can vary widely, making it difficult for policymakers and others to respond accordingly. Many of those predictions tend not to hold up over time if they fail to account for the full range of biological factors that can influence an organism’s survival rate: species demographics, competition from other organisms, species mobility, and the capacity to adapt and evolve.

“We haven’t been able to sufficiently determine what species composition future ecosystems will have, and how their functions and services for mankind will change,” says co-author Dr. Karin Johst of the Helmholtz Centre for Environmental Research and the German Centre for Integrative Biodiversity Research. “This is because current ecological models often do not include important biological processes and mechanisms: so far only 23 percent of the reviewed studies have taken into account biological mechanisms.”

Generating more accurate predictions is essential for global conservation efforts. Many species are already moving to higher ground or toward the poles to seek cooler temperatures as global temperatures rise. But the capacity of different organisms to survive varies greatly. Some species of frog, for instance, can traverse their terrain for miles to remain in a habitable environment. Other species, such as some types of salamander, are less mobile and capable of moving only a few meters over generations.

“New Zealand’s strong foundation in ecological research will help,” explains study co-author Dr. William Godsoe, a Lincoln University lecturer and member of New Zealand’s Bio-Protection Research Centre. “One of our hopes is to build on these strengths and highlight new opportunities to improve predictions by explicitly considering evolution, interactions among species, and dispersal.” This will aid in the development of strategies to manage impacts on species and ecosystems before they become critical.

With more than 8.7 million species worldwide, gathering the necessary biological information to improve predictions is a daunting task. Even a sampling of key species would be beneficial, the authors say, as the more sophisticated models will allow scientists to extrapolate their predictions and apply them to multiple species with similar traits.

The researchers are calling for the launch of a global campaign to be spearheaded by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services or IPBES. The IPBES operates under the auspices of four United Nations entities and is dedicated to providing scientific information to policymakers worldwide. One thousand scientists from all over the world currently contribute to the work of IPBES on a voluntary basis. The scientists are also encouraging conservation strategies to support biodiversity such as maintaining dispersal corridors, and preserving existing natural habitats and genetic diversity.

“Our biggest challenge is pinpointing which species to concentrate on and which regions we need to allocate resources,” says UConn Associate Professor Urban. In an earlier study in Science , Urban predicted that as many as one in six species internationally could be wiped out by climate change. “We are at a triage stage at this point. We have limited resources and patients lined up at the door.”

Passage 2

Forecasting climate change’s effects on biodiversity hindered by lack of data

An international group of biologists is calling for data collection on a global scale to improve forecasts of how climate change affects animals and plants. Accurate model predictions can greatly aid efforts to protect biodiversity from disturbances such as climate change and urban sprawl by helping scientists and decision-makers better understand, anticipate and respond to threats that imperil species and ecosystems.

In a paper published in Science on Thursday (Sept. 8), biologists cite a critical lack of data on key biological mechanisms C such as how animals and plants spread during their lifetime and how they evolve in response to changes in the environment – as the main obstacle to improving models’ ability to forecast species’ response to climate change.

“This paper is a call to arms,” said Patrick Zollner, article co-author and Purdue associate professor of wildlife science. “The world is in dire circumstances. We’re losing a lot of species, and we’re largely unaware why. How do we need to rethink the kind of data we’re collecting so we can take advantage of modern modeling tools to understand the outcomes of climate change for ecological systems? This could help us forestall losing wildlife that we later deeply regret.”

The group outlines two key problems that hinder the capability of current models to make realistic predictions about biological responses to climate change.

Most models are descriptive, based on statistical correlations and observations, and fail to capture the underlying processes that produce observed changes. For example, a descriptive model might show that lynx in the northern U.S. are declining while bobcat populations in the same region are on the rise. Understanding what is driving this change requires a different sort of model, one that incorporates biological mechanisms. A mechanistic model that accounts for how warming temperatures affect snow depth, for instance, could provide insights into why bobcats – better adapted to habitats with less snow – are gaining a competitive edge over lynx. But 77 percent of current models of climate change’s impacts on wildlife do not include biological mechanisms.

Another challenge is that as models have grown in sophistication, they have far outpaced data collection. Put another way, a model is like a state-of-the-art kitchen, but the cupboards are bare.

“We can now build videogame-like environments with computers where we can create multiple versions of Earth and ask what the implications under different scenarios are,” Zollner said. “But our ability to learn from these tools is constrained by the kinds of data we have.”

The group advanced several proposals on how to improve models, collect missing data and leverage available data to make broader predictions.

They identified six biological mechanisms that influence wildlife’s responses to climate change: physiology; demography and life history; evolutionary potential and adaptation; interactions between species; movement over land or water; and responses to changes in the environment. They ranked the information needed to account for these mechanisms in models and suggested proxies for data that are missing or hard to collect.

A globally coordinated effort to fill data gaps could greatly advance improvements in models and informed conservation approaches, the researchers wrote.
