Rtl today – climate variability: twentieth century warming “unmatched” in 2000 years

Global temperatures rose faster at the end of the 20th century than at any time in the past 2,000 years, according to a study released Wednesday that experts say undermines questioning by climate deniers about the role of climate change. humanity in global warming. As Europe suffocated in a second record-breaking heat wave in a […]

Current Climate Models Can Predict Global Warming Decades Ahead – ScienceDaily

A new reconstruction of global mean surface temperature trends over the past 2,000 years has identified the major causes of decade-scale climate change. The analysis suggests that the Earth’s current rate of warming, caused by human emissions of greenhouse gases, is greater than any previously observed rate of warming. The researchers also found that airborne […]

How does climate variability contribute to global crop failures?

According to a recent paper published on July 3 in the journal Scientists progress (1). For example, in 1983, ENSO was responsible for the largest synchronous harvest failure in recorded modern history. Globally synchronous harvest failures refer to the simultaneous failure of a single harvest in several as far apart as the United States, China, […]

News – Climate models overestimate the impact of carbon dioxide on temperature, study confirms

A new study shows that climate models consistently overestimate the warming effect of rising carbon dioxide concentrations on climate. Researchers have long known that there are significant discrepancies between climate model projections, based on assumptions about the effect of anthropogenic greenhouse gas emissions on global temperatures, and actual climate observations. , but modellers and those […]
