We present recent observed climate trends for carbon dioxide concentration, global mean air temperature, and global sea level, and we compare these trends to previous model projections as summarized in the 2001 assessment report of the Intergovernmental Panel on Climate Change (IPCC). The IPCC scenarios and projections start in the year 1990, which is also the base year of the Kyoto protocol, in which almost all industrialized nations accepted a binding commitment to reduce their greenhouse gas… 
Comparing climate projections to observations up to 2011
We analyse global temperature and sea-level data for the past few decades and compare them to projections published in the third and fourth assessment reports of the Intergovernmental Panel on
Statistical climate-change scenarios
We report on climate projections generated by a simple model of climate change. The model captures the effects of variations in surface solar radiation, using information over the period 1959–2002
Global sea level linked to global temperature
A simple relationship linking global sea-level variations on time scales of decades to centuries to global mean temperature is proposed and tested on synthetic data from a global climate model for the past millennium and the next century.
Comment to "Recent Climate Observations Compared to Projections" by Rahmstorf et al
It is shown in this comment that considering the Mauna Loa observation of the atmospheric carbon dioxide concentration and the mean near surface temperature anomalies for the period from the
How do UK climate scenarios compare with recent observations
National climate scenarios are increasingly being used in long-term strategic planning and decision-making, but their projections have rarely been compared with observations. Recent changes in
Lower bounds to future sea-level rise
Abstract Sea-level rise is among the most important changes expected as a consequence of anthropogenic global warming. Climate model-based projections made until the Fourth Assessment Report (AR4) of
Antarctic climate change and the environment
Abstract The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these
Biases and Model Agreement in Projections of Climate Extremes over the Tropical Pacific
AbstractUsing the Coupled Model Intercomparison Project phase 3 (CMIP3) general circulation models (GCMs), projections of a range of climate extremes are explored for the western Pacific. These
Climate Change 2009: Faster Change & More Serious Risks
The IPCC's Fourth Assessment Report (AR4) is an outstanding source of information on our current scientific understanding of the climate system and how it is responding to the changes in the
Intergovernmental Panel for Climate Change (IPCC) and attribution and prediction of climate: Progress since the fourth assessment
The IPCC (Intergovernmental Panel on Climate Change) is a primary user of studies of the ocean and how it is changing. Following an introduction to the IPCC, the role of the ocean in climate is


Interannual variability in upper ocean heat content, temperature, and thermosteric expansion on global scales
[1] Satellite altimetric height was combined with approximately 1,000,000 in situ temperature profiles to produce global estimates of upper ocean heat content, temperature, and thermosteric sea level
A 20th century acceleration in global sea-level rise
[1] Multi-century sea-level records and climate models indicate an acceleration of sea-level rise, but no 20th century acceleration has previously been detected. A reconstruction of global sea level
