Rain, hot and humid days in December due to ‘climate variability’ | Nagpur News

[ad_1] Nagpur: Wondering why this December is rainier, foggy, and wetter than the norm for Nagpur? “Climate variability” is the answer, say weather experts. Christmas came as a surprise to citizens, with many parts of the city receiving low rainfall. Nagpur Regional Meteorological Center (RMC) officials said it started raining late Wednesday night, with drizzle […]

ABARES analyzes the effects of drought and climate variability on Australian farms

[ad_1] Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) Knowledge report provides analysis on the effects of climate variability on Australian crop and livestock farms. The report examines both short-term climate risks such as drought and long-term changes in climatic conditions. ABARES Senior Economist Dr Neal Hughes said that an observed change to […]

Early climate models were spot on when it came to global warming

Climate skeptics have long questioned the accuracy of computer models that predict global warming, but most early climate models turn out to be spot-on, according to a flashback from University of California climatologists at Berkeley, Massachusetts Institute of Technology and NASA. Of 17 climate models published between the early 1970s and late 2000s, 14 were […]

Climate models have always been right, new study finds

A recent to study computer climate models dating back to the 1970s have shown them to be very accurate in relation to what actually happened over the following decades. This builds confidence in modern models that predict further changes in the future. In the 1970s, climatologists began to report the increasing amount of carbon dioxide […]

Even 50-year-old climate models correctly predicted global warming

In climate science, models are essential tools in trying to understand an uncertain future. But attempts to predict the future are easy targets, and climate change skeptics have long sought to poke holes in past climate change predictions to undermine the credibility of today’s dire warnings. Now a full review of climate models dating back […]

Even 50 years ago, climate models were far more accurate than deniers claim

It’s a common refrain from those who question the findings of climate science: the computer models scientists use to project future global warming are inaccurate and shouldn’t be trusted to help policymakers decide whether to they must take potentially costly measures to limit greenhouse gas emissions. A new study effectively quells this argument by examining […]

Nailed: Early climate models accurately predicted effects of global warming, study finds | The Weather Channel – Articles from The Weather Channel

This color-coded map shows global surface temperature anomalies. Temperatures above normal are shown in red and temperatures below normal are shown in blue. (NASA Goddard Space Flight Center) Of the 17 climate change models examined, 14 were accurate enough to predict the effects of global warming. The researchers fed the actual emission levels into the […]

Climate models are often attacked, but most of the time they are remarkably good

A new study finds that past computer simulations of climate change have been quite accurate. Credit: Associated Press Computer models used to simulate the effects of heat-trapping gases on global temperatures have been quite accurate in their predictions, according to a new study. After years of hearing reviewers criticize the models’ accuracy, climatologist Zeke Hausfather […]

Climate models have understood global warming well

There’s a favorite argument among those who doubt mainstream climate science: climate models overestimate the rate at which the Earth is warming. This claim resurfaces time and time again and is often based on single instances of uncertainty or hand-picked data. Various studies have looked closely at individual climate models in recent years and have […]

How successful have climate models really been in predicting the future?

A new paper by Hausfather and his colleagues (including me) has just been published with the most comprehensive assessment of climate model projections since the 1970s. Bottom line? Once you fixed the small errors in the projected overrides, they performed remarkably well. Climate models are central to our understanding of our future climate. They have […]
