Barack Obama (above in Feb. 2018) was awarded the Nobel Peace Prize in 2009

Theodore Roosevelt (1906)

The United States of America was among the first to infuse the ideal of peace into practical politics. Peace and arbitration treaties have now been concluded between the United States and the governments of several countries. But what has especially directed the attention of the friends of peace and of the whole civilized world to the United States is President Roosevelt's happy role in bringing to an end the bloody war recently waged between two of the world's great powers, Japan and Russia.

On behalf of the Norwegian Parliament, I now present to you, Mr. Ambassador, the Peace Prize along with its insignia, and I add the request that you convey to the President the greetings of the Norwegian people and their gratitude for all that he has done in the cause of peace. I would also add the wish that this eminent and highly gifted man may be blessed with the opportunity of continuing his work to strengthen the ideal of peace and to secure the peace of the world.

Woodrow Wilson (1919, presented in 1920)

As the name of President Wilson comes to the fore on this occasion as the recipient of the Peace Prize, I know that the award is accompanied by the thanks of the people of Norway, because in his celebrated Fourteen Points

the President of the United States has succeeded in bringing a design for a fundamental law of humanity into present-day international politics. The basic concept of justice on which it is founded will never die, but will steadily grow in strength, keeping the name of President Wilson fresh in the minds of future generations.

Jimmy Carter (2002)

The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2002 to Jimmy Carter, for his decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development.

During his presidency (1977-1981), Carter's mediation was a vital contribution to the Camp David Accords between Israel and Egypt, in itself a great enough achievement to qualify for the Nobel Peace Prize. At a time when the cold war between East and West was still predominant, he placed renewed emphasis on the place of human rights in international politics.

Through his Carter Center, which celebrates its 20th anniversary in 2002, Carter has since his presidency undertaken very extensive and persevering conflict resolution on several continents. He has shown outstanding commitment to human rights, and has served as an observer at countless elections all over the world. He has worked hard on many fronts to fight tropical diseases and to bring about growth and progress in developing countries. Carter has thus been active in several of the problem areas that have figured prominently in the over one hundred years of Peace Prize history.

In a situation currently marked by threats of the use of power, Carter has stood by the principles that conflicts must as far as possible be resolved through mediation and international co-operation based on international law, respect for human rights, and economic development.

Barack Obama (2009)

The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2009 is to be awarded to President Barack Obama for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples. The Committee has attached special importance to Obama's vision of and work for a world without nuclear weapons.

Obama has as President created a new climate in international politics. Multilateral diplomacy has regained a central position, with emphasis on the role that the United Nations and other international institutions can play. Dialogue and negotiations are preferred as instruments for resolving even the most difficult international conflicts. The vision of a world free from nuclear arms has powerfully stimulated disarmament and arms control negotiations. Thanks to Obama's initiative, the USA is now playing a more constructive role in meeting the great climatic challenges the world is confronting. Democracy and human rights are to be strengthened.

Only very rarely has a person to the same extent as Obama captured the world's attention and given its people hope for a better future. His diplomacy is founded in the concept that those who are to lead the world must do so on the basis of values and attitudes that are shared by the majority of the world's population.

For 108 years, the Norwegian Nobel Committee has sought to stimulate precisely that international policy and those attitudes for which Obama is now the world's leading spokesman. The Committee endorses Obama's appeal that 'Now is the time for all of us to take our share of responsibility for a global response to global challenges.'

Al Gore (2007)

The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2007 is to be shared, in two equal parts, between the Intergovernmental Panel on Climate Change (IPCC) and Albert Arnold (Al) Gore Jr. for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change.

Indications of changes in the earth's future climate must be treated with the utmost seriousness, and with the precautionary principle uppermost in our minds. Extensive climate changes may alter and threaten the living conditions of much of mankind. They may induce large-scale migration and lead to greater competition for the earth's resources. Such changes will place particularly heavy burdens on the world's most vulnerable countries. There may be increased danger of violent conflicts and wars, within and between states.

Through the scientific reports it has issued over the past two decades, the IPCC has created an ever-broader informed consensus about the connection between human activities and global warming. Thousands of scientists and officials from over one hundred countries have collaborated to achieve greater certainty as to the scale of the warming. Whereas in the 1980s global warming seemed to be merely an interesting hypothesis, the 1990s produced firmer evidence in its support. In the last few years, the connections have become even clearer and the consequences still more apparent.

Al Gore has for a long time been one of the world's leading environmentalist politicians. He became aware at an early stage of the climatic challenges the world is facing. His strong commitment, reflected in political activity, lectures, films and books, has strengthened the struggle against climate change. He is probably the single individual who has done most to create greater worldwide understanding of the measures that need to be adopted.

By awarding the Nobel Peace Prize for 2007 to the IPCC and Al Gore, the Norwegian Nobel Committee is seeking to contribute to a sharper focus on the processes and decisions that appear to be necessary to protect the worlds future climate, and thereby to reduce the threat to the security of mankind. Action is necessary now, before climate change moves beyond mans control.'
