Sentences with phrase «natural climate drivers»

Scientists use climate computer models to compare these observed changes with natural climate drivers and human climate drivers.

When climate models include only recorded natural climate drivers, the models can not accurately reproduce the observed warming of the past half century.

As former NASA employees, we feel that NASA's advocacy of an extreme position, prior to a thorough study of the possible overwhelming impact of natural climate drivers is inappropriate.

Scientists have studied and ruled out natural climate drivers as the main cause of global warming since the preindustrial era.

Global temperatures could break through the 1.5 °C barrier negotiated at the Paris conference as early as 2026 if a slow - moving, natural climate driver known as the Interdecadal Pacific Oscillation (IPO) has, as suspected, moved into a positive phase.

Natural climate drivers include the energy from the sun; aerosols from periodic volcanic eruptions, dust, and salt spray; natural carbon cycle processes like termite mounds in Africa that emit methane, or tiny organisms in the ocean surface that take up carbon dioxide; and variation in snow and ice cover that change how much the Earth's surface reflects the sun's energy back into space (referred to as albedo).

Uncertainty in natural climate drivers, for example how much solar output will change over this century, also affects the accuracy of projections.

But none of these natural climate drivers reproduced the long - term observed drying, indicating this trend is due to human activity.

As Skeptical Science readers are undoubtely well aware, the impact of natural climate drivers has been very thoroughly studied, and they simply can not account for the observed global warming or climate change, especially over the past 50 - 65 years (Figure 1).

Although this is not a certainty, there is no plausible basis for thinking that a stronger response to a natural climate driver should imply a weaker response to an anthropogenic one.
