The earth has entered a period of hydrological, climatological, and biological change that differs from previous episodes of global change in the extent to which it is human in origin. To explain or predict the course of the present global environmental changes, one must therefore understand the human sources, consequences, and responses, some of which can alter the course of global change. This book examines what is known about the human dimensions of global environmental change, identifies the major immediate needs for knowledge, and recommends a strategy for building that knowledge over the next years.
The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature , there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases. The controversy is, by now, political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. Political and popular debate concerning the existence and cause of global warming includes the reasons for the increase seen in the instrumental temperature record , whether the warming trend exceeds normal climatic variations, and whether human activities have contributed significantly to it. Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing, that human activity is the cause, and that it is without precedent in at least years. Global warming remains an issue of widespread political debate, often split along party political lines, especially in the United States.
This introduction to a special issue of Climatic Change argues that it is timely and welcome to intensify historical research into climate change and climate as factors of history. This is also already an ongoing trend in many disciplines. The article identifies two main strands in historical work on climate change, both multi-disciplinary: one that looks for it as a driver of historical change in human societies, the other that analyzes the intellectual and scientific roots of the climate system and its changes. The five papers all serve as examples of intellectual, political, and social responses to climate-related phenomena and their consequences ones that have manifested themselves relatively recently and are predominantly attributable to anthropogenic climate change. The historicizing work that these papers perform lies in the analysis of issues that are rising in societies related to climate change in its modern anthropogenic version. The history here is not so much about past climates, although climate change itself is always directly or indirectly present in the story, but rather about history as the social space where encounters take place and where new conditions for humans and societies and their companion species and their life worlds in natures and environments are unfolding and negotiated. With climate change as a growing phenomenon historicizing climate change in this version will become increasingly relevant.
What is global warming? What causes global warming? What is climate change? Is it different from global warming? What is a climate change impact? What does global warming have to do with severe weather, like storms, heat waves, droughts, and hurricanes?
Over the last several decades, governments have collectively pledged to slow global warming. But despite intensified diplomacy, the world could soon face devastating consequences of climate change. Through the Kyoto Protocol and the Paris Agreement, countries agreed to reduce greenhouse gas emissions, but the amount of carbon dioxide in the atmosphere keeps rising, heating the Earth at an alarming rate.

This indicator describes how the levels of major greenhouse gases in the atmosphere have changed over time. This figure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through , measured in parts per million ppm. The data come from a variety of historical ice core studies and recent air monitoring sites around the world. Each line represents a different data source.

How can one best manage the unpredictable and rapidly evolving relationship between human beings and the biosphere?
NASA is a world leader in climate studies and Earth science. While its role is not to set climate policy or prescribe particular responses or solutions to climate change, its purview does include providing the robust scientific data needed to understand climate change. NASA then makes this information available to the global community — the public, policy- and decision-makers and scientific and planning agencies around the world. Climate change is one of the most complex issues facing us today. It involves many dimensions — science, economics, society, politics and moral and ethical questions — and is a global problem, felt on local scales, that will be around for decades and centuries to come.
