An analysis of the worldwide issue of global warming in the past decades

Two millennia of mean surface temperatures according to different reconstructions from climate proxieseach smoothed on a decadal scale, with the instrumental temperature record overlaid in black. Multiple independently produced datasets confirm that from to the global average land and ocean surface temperature increased by 0. The rest has melted ice and warmed the continents and the atmosphere. Cold blob North Atlantic Difference between average temperature in — compared to the period, showing strong arctic amplification.

Marc Morano - Climate Depot November 4, 2: Yet the months since then show no global warming at all Fig. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset shows no global warming for 18 years 9 months since Februarythough one-third of all anthropogenic forcings have occurred during the period of the Pause.

The accidental delegate from Burma provoked shrieks of fury from the congregation during the final benediction in Doha three years ago, when he said the Pause had endured for 16 years. Now, almost three years later, the Pause is almost three years longer.

It is worth understanding just how surprised the modelers ought to be by the persistence of the Pause. NOAA, in a very rare fit of honesty, admitted in its State of the Climate report that 15 years or more without global warming would demonstrate a discrepancy between prediction and observation.

The steepness of this predicted response can be seen in Fig. But, despite the very substantial forcings in the 18 years 9 months since Februarynot a flicker of warming has resulted. Models predict rapid initial warming in response to a forcing.

Instead, no warming at all is occurring. Based on Roe At the Heartland and Philip Foster events in Paris, I shall reveal in detail the three serious errors that have led the models to over-predict warming so grossly. The RSS temperature record is beginning to reflect its magnitude.

From next month on, the Pause will probably shorten dramatically and may disappear altogether for a time. The hiatus period of 18 years 9 months is the farthest back one can go in the RSS satellite temperature record and still show a sub-zero trend.

The start date is not cherry-picked: And the graph does not mean there is no such thing as global warming. Going back further shows a small warming rate. And yes, the start-date for the Pause has been inching forward, though just a little more slowly than the end-date, which is why the Pause continues on average to lengthen.

So long a stasis in global temperature is simply inconsistent not only with the extremist predictions of the computer models but also with the panic whipped up by the rent-seeking profiteers of doom rubbing their hands with glee in Paris. However, the much-altered surface tamperature datasets show a small warming rate Fig.

Bearing in mind that one-third of the 2. As always, a note of caution. Merely because there has been little or no warming in recent decades, one may not draw the conclusion that warming has ended forever.

The trend lines measure what has occurred: Near-term projections of warming at a rate equivalent to 2. Predicted temperature change, January to Septemberat a rate equivalent to 1. In a rational scientific discourse, those who had advocated extreme measures to prevent global warming would now be withdrawing and calmly rethinking their Javier Summary: Modern Global Warming has been taking place for the past years.

It is the last of several multi-century warming periods that have happened during the Neoglacial cooling of the past years. Analysis of Holocene climate cycles shows that the period AD should be a period of warming. The evidence. The scientific consensus is clear. Building on two previous studies, a landmark peer-reviewed study evaluated 10, scientists to confirm that over 97 percent climate scientists agree, and over 97 percent of scientific articles find that global warming is real and largely caused by humans..

A more recent peer-reviewed paper examined existing studies on consensus in climate research, and. Temperature data showing rapid warming in the past few decades. According to NASA data, was the warmest year since , continuing a long-term trend of rising global temperatures.

Arctic sea ice decline, sea level rise, retreat of glaciers: Global warming has led to decades of shrinking and thinning in a warm climate that has put the Arctic sea ice in a precarious position, it is now vulnerable to atmospheric anomalies.

Projections of declines in Arctic sea ice vary. According to an analysis by NASA scientists, the average global temperature has increased by about °Celsius (° Fahrenheit) since Two-thirds of the warming has occurred since The world is getting warmer, whatever the cause.

Instead, global area burned appears to have overall declined over past decades, and there is increasing evidence that there is less fire in the global landscape today than centuries ago.

This is an eye-opening read in light of the hype surrounding the Ft. McMurray fires of recent weeks and the general warming-is-causing-more-fires-trope that is.
