[1] We use a suite of global climate model simulations for the 20th century to assess the contribution of solar forcing to the past trends in the global mean temperature. In particular, we examine how robust different published methodologies are at detecting and attributing solar-related climate change in the presence of intrinsic climate variability and multiple forcings. We demonstrate that naive application of linear analytical methods such as regression gives nonrobust results. We also… 

Spatial Signature of Solar Forcing over the North Atlantic Summer Climate in the Past Millennium

Abstract. We investigate the effects of solar forcing during summer on the North Atlantic climate in comprehensive simulations of the preindustrial last millennium. We use two Earth System Models

The literature relevant to how solar variability influences climate is vast—but much has been based on inadequate statistics and non-robust procedures. The common pitfalls are outlined in this

A critical look at solar-climate relationships from long temperature series

A key issue of climate change is to identify the forcings and their relative contributions. The solar-climate relationship is currently the matter of a fierce debate. We address here the need for

Addendum: Small influence of solar variability on climate over the past millennium

The climate of the past millennium was marked by substantial decadal and centennial scale variability in the Northern Hemisphere1. Low solar activity has been linked to cooling during the Little Ice

Problems with solar, volcanic, and ENSO attribution using multiple linear regression methods on temperatures from 1979–2012

Abstract. The effectiveness of multiple linear regression approaches in removing solar, volcanic, and El Nino Southern Oscillation (ENSO) influences from the recent (1979–2012) surface temperature

Causes of climate change over the historical record

This review addresses the causes of observed climate variations across the industrial period, from 1750 to present. It focuses on long-term changes, both in response to external forcing and to

What influence will future solar activity changes over the 21st century have on projected global near‐surface temperature changes?

[1] During the 20th century, solar activity increased in magnitude to a so-called grand maximum. It is probable that this high level of solar activity is at or near its end. It is of great interest

Climate of the Past Statistical issues about solar – climate relations

The relationship between solar activity and temperature variation is a frequently discussed issue in climatology. This relationships is usually hypothesized on the basis of statistical analyses of

Solar and Planetary Oscillation Control on Climate Change: Hind-Cast, Forecast and a Comparison with the Cmip5 Gcms

Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a background



Phenomenological solar contribution to the 1900–2000 global surface warming

We study the role of solar forcing on global surface temperature during four periods of the industrial era (1900–2000, 1900–1950, 1950–2000 and 1980–2000) by using a sun‐climate coupling model based

Is climate sensitive to solar variability

The causes of global warming—the increase of approximately 0.8±0.1 °C in the average global temperature near Earth’s surface since 1900—are not as apparent as some recent scientific publications and

Volcanic and Solar Forcing of Climate Change during the Preindustrial Era

The climate response to variability in volcanic aerosols and solar irradiance, the primary forcings during the preindustrial era, is examined in a stratosphere-resolving general circulation model.

We have previously placed the solar contribution to recent global warming in context using observations and without recourse to climate models. It was shown that all solar forcings of climate have

How natural and anthropogenic influences alter global and regional surface temperatures: 1889 to 2006

To distinguish between simultaneous natural and anthropogenic impacts on surface temperature, regionally as well as globally, we perform a robust multivariate analysis using the best available

Attribution of twentieth century temperature change to natural and anthropogenic causes

Abstract  We analyse possible causes of twentieth century near-surface temperature change. We use an “optimal detection” methodology to compare seasonal and annual data from the coupled

Global temperature change

Comparison of measured sea surface temperatures in the Western Pacific with paleoclimate data suggests that this critical ocean region is approximately as warm now as at the Holocene maximum and within ≈1°C of the maximum temperature of the past million years.

Climate sensitivity of the Earth to solar irradiance

The mean surface temperature of the Earth depends on various climate factors with much attention directed toward possible anthropogenic causes. However, one must first determine the stronger effects

What Can Present Climate Models Tell Us about Climate Change?

Climate models are evaluated in terms of their ability to describe the past climatic changes. Past climatic trends are inferred from fitting a truncated Taylor series to the observational record and

Phenomenological solar signature in 400 years of reconstructed Northern Hemisphere temperature record

We study the solar impact on 400 years of a global surface temperature record since 1600. This period includes the pre‐industrial era (roughly 1600–1800 or 1600–1900), when negligible amount of
