At the very least, proponents of continuing global warming and climate change would perhaps be wise not to make the recent warming trend in recorded temperatures a central plank in their argument.»

A recent study by Cowtan et al. (paper here) suggests that accounting for these biases between the global temperature record and those taken from climate models reduces the divergence in trend between models and observations since 1975 by over a third.

They clearly have not «proved» skill at predicting in a hindcast mode, changes in climate statistics on the regional scale, and even in terms of the global average surface temperature trend, in recent years they have overstated the positive trend.

... incomplete and misleading because it 1) omits any mention of several of the most important aspects of the potential relationships between hurricanes and global warming, including rainfall, sea level, and storm surge; 2) leaves the impression that there is no significant connection between recent climate change caused by human activities and hurricane characteristics and impacts; and 3) does not take full account of the significance of recently identified trends and variations in tropical storms in causing impacts as compared to increasing societal vulnerability.

To date, while various effects and feedbacks constrain the certainty placed on recent and projected climate change (EG, albedo change, the response of water vapour, various future emissions scenarios etc), it is virtually certain that CO2 increases from human industry have reversed and will continue to reverse the downward trend in global temperatures that should be expected in the current phase of the Milankovitch cycle.

Now, adding to this miserably low warming influence of CO2 is the recent admission by establishment climate science that natural climatic forces have a powerful say in the trend of global temperatures, regardless of human CO2 emissions.

Proxy - based reconstructions of past climate provide insights into externally forced and intrinsic variability over regional to global scales and can be used to place recent trends in a long - term context.

The Intergovernmental Panel on Climate Change reported in its most recent scientific assessment that «[n] o robust trends in annual numbers of tropical storms, hurricanes, and major hurricanes... have been identified over the past 100 years in the North Atlantic basin,» and that there are «no significant observed trends in global tropical cyclone frequency.»

The discrepancy between recent observed and simulated trends in global mean surface temperature has provoked a debate about possible causes and implications for future climate change projections.

The simulations also produce an average increase of 2.0 °C in twenty - first century global temperature, demonstrating that recent observational trends are not sufficient to discount predictions of substantial climate change and its significant and widespread impacts.

That conclusion is based not on climate models or recent trends in forest fires, but rather on records of forest fires that occurred more than a millennium ago, during the Medieval Climate Anomaly, a period when global temperatures were comparable to what they are today, and about half a degree warmer (on the Celsius scale) than they had been for several centuriesclimate models or recent trends in forest fires, but rather on records of forest fires that occurred more than a millennium ago, during the Medieval Climate Anomaly, a period when global temperatures were comparable to what they are today, and about half a degree warmer (on the Celsius scale) than they had been for several centuriesClimate Anomaly, a period when global temperatures were comparable to what they are today, and about half a degree warmer (on the Celsius scale) than they had been for several centuries prior.
