How do we know what is happening to concentrations of greenhouse gases in the air? How much have greenhouse gas concentrations increased? How long do the greenhouse gases last in the atmosphere?

Climate Change Stories. December 10, Scientists from The Nature Conservancy are answering some of the most frequently asked questions so that you have the information you need to speak up and take action. Is it climate change, global warming, or global climate crisis? What are the main threats of climate change?

Climate Change FAQs

The issue can be overwhelming. The science is complicated. Predictions about the fate of the planet carry endless caveats and asterisks. This should give you a running start on understanding the problem. As of early , the Earth had warmed by roughly 2 degrees Fahrenheit, or more than 1 degree Celsius, since , when records began at a global scale. That figure includes the surface of the ocean. The warming is greater over land, and greater still in the Arctic and parts of Antarctica.

In discussing "climate change and health" we must distinguish between the health impacts of several meteorological exposures: weather, climate variability and climate change. Weather is the continuously changing condition of the atmosphere, usually considered on a time scale that extends from minutes to weeks. Climate is the average state of the lower atmosphere, and the associated characteristics of the underlying land or water, in a particular region, usually spanning at least several years. Climate change occurs over decades or longer time-scales. Until now, changes in the global climate have occurred naturally, across centuries or millennia, because of continental drift, various astronomical cycles, variations in solar energy output and volcanic activity. Over the past few decades it has become increasingly apparent that human actions are changing atmospheric composition, thereby causing global climate change 1. The Sun is the principal driving force for weather and climate.

Quite small. Humans have caused major climate changes to happen already, and we have set in motion more changes still. Even if we stopped emitting greenhouse gases today, global warming would continue to happen for at least several more decades, if not centuries. Examples are familiar — rain, snow, clouds, winds, thunderstorms, heat waves and floods. Even if the amount of radiation coming from the Sun were to decrease as it has before, it would not significantly affect the global warming coming from long-lived, human-emitted greenhouse gases. Yes, evidence shows warming from to the present, with the six most recent years , , , , , and being the six warmest years globally since
