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 estimates of each together with the observed surface temperature record from 1889 to 2006. The results enable us to compare, for the first time from observations, the geographical distributions of responses to individual influences consistent with their global impacts. We find a response to solar forcing… 

Attribution of observed historical near‒surface temperature variations to anthropogenic and natural causes using CMIP5 simulations

We have carried out an investigation into the causes of changes in near‒surface temperatures from 1860 to 2010. We analyze the HadCRUT4 observational data set which has the most comprehensive set of

How will Earth's surface temperature change in future decades?

Reliable forecasts of climate change in the immediate future are difficult, especially on regional scales, where natural climate variations may amplify or mitigate anthropogenic warming in ways that

Causes of irregularities in trends of global mean surface temperature since the late 19th century

Reconstruction accuracy shows that known external and internal forcing factors explain all the main variations in GST between 1891 and 2015, allowing for the current understanding of their uncertainties.

Impact of the Atlantic Multidecadal Oscillation (AMO) on deriving anthropogenic warming rates from the instrumental temperature record

Abstract. The instrumental surface air temperature record has been used in several statistical studies to assess the relative role of natural and anthropogenic drivers of climate change. The results

Variability of high latitude amplification of anthropogenic warming

Climate models have long predicted that the high latitude response of near‐surface air temperatures should be greater than at lower latitudes as a result of snow/ice feedbacks. Here we show that a

Empirical estimation of anthropogenic and natural contributions to surface air temperature trends at different latitudes

How strong are quantitative contributions of the key natural modes of climate variability and the anthropogenic factor characterized by the changes of the radiative forcing of greenhouse gases in the

Wyoming provides more fossil fuels to the remainder of the United States than any other state or country, and its citizens remain skeptical of anthropogenic influences on their climate. However, much

Evaluation of Labrador air temperatures over the past century (1881–2011) shows multi-scale climate variability and strong linkages with ocean-atmospheric modes of variability and external forcings.

The role of natural climatic variation in perturbing the observed global mean temperature trend

Controversy continues to prevail concerning the reality of anthropogenically-induced climatic warming. One of the principal issues is the cause of the hiatus in the current global warming trend.

Long-term trends in Arctic surface temperature and potential causality over the last 100 years

The rate of warming of the Arctic surface temperature has exceeded that of the global surface temperature in recent decades. However, the underlying process and causes of the long-term warming remain



Quantifying anthropogenic influence on recent near-surface temperature change

We assess the extent to which observed large-scale changes in near-surface temperatures over the latter half of the twentieth century can be attributed to anthropogenic climate change as simulated by

Accounting for the effects of volcanoes and ENSO in comparisons of modeled and observed temperature trends

Several previous studies have attempted to remove the effects of explosive volcanic eruptions and El Nino-Southern Oscillation (ENSO) variability from time series of globally averaged surface and

Uncertainty estimates in regional and global observed temperature changes: A new data set from 1850

[1] The historical surface temperature data set HadCRUT provides a record of surface temperature trends and variability since 1850. A new version of this data set, HadCRUT3, has been produced,

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

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

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

Climate simulations for 1880–2003 with GISS modelE

We carry out climate simulations for 1880–2003 with GISS modelE driven by ten measured or estimated climate forcings. An ensemble of climate model runs is carried out for each forcing acting

Reconstruction of Monthly SST in the Tropical Pacific Ocean during 1868–1993Using Adaptive Climate Basis Functions

Abstract An EOF-based reconstruction of monthly SST anomaly fields is calculated for the years 1868–1993 in the tropical Pacific Ocean. The EOFs are computed from optimally interpolated SST anomaly
