Harper has a wonderful description of the ‘economic efflorescence’ of the ‘Roman Climate Optimum’. Things take a first turn for the worse in Chapter 3. Theophrastus (371 – c. 287 BC) wrote that date trees could grow in Greece if they were planted, but that they could not set fruit there. “The Roman Warm Period or the Roman climatic optimum has been proposed as a period of unusually warm weather in Europe and the North Atlantic that ran from approximately 250 BC to 400 AD” What is Rome famous for (other than killing and conquering and so on)? Other articles where Climatic Optimum is discussed: global warming: Climatic variation since the last glaciation: …sometimes referred to as the Mid-Holocene Climatic Optimum. The thing that differs today is the injection of the massive slug of CO2 long-sequestered from the carbon cycle back into it. We hypothesis the potential link between this Roman Climatic Optimum and the expansion and subsequent decline of the Roman Empire. Share this: Click … The great empire reached its extent during the Roman Climate Optimum from 200BC to AD150, but fortune would stop smiling and by 450AD Europe had entered the Late Antique Little Ice Age. The climate conditions of the MWP are often compared to those of the late 20th and early 21st centuries in arguments over the causes and potential effects of modern climate trends. The period from 200 BC to 150 AD — when the Roman project was at its most healthy — also coincided with what is often referred to as the ‘Roman Climate Optimum’, when the weather warmed up due to high solar activity. The author identifies 6 causes of climate change: 1) Variations in the tilt of the earth’s axis - 41,000 year cycle. Unlike the anomalously favorable climate during the Roman Climate Optimum — some 350 years of unusually warm and moist climate between around … This climate phase corresponds to what is known as the ‘Roman Climatic Optimum’ characterized by prosperity and expansion of the Empire, giving warmth and sunlight to crops. Around 5,500 to 5,000 years before present occurred the Piora cold period, which is named after the Val Piora valley in Switzerland, which was the first place, where it was identified by using pollen analysis. The climate in the Mediterranean during this period was warm and moist, excellent for the agriculture that underpinned the empire. The Empire's greatest extent under Trajan coincided with the Roman climatic optimum. Virus numbers could be erratic post-Thanksgiving. Now, why are we supposed to be afraid of going back to this type of climate again? But from the middle of the second century AD, “the Romans’ luck ran into short supply…. The current climate was not seen as being particularly warm - certainly less warm that the Medieval period (called the "Medieval Warm Period", or MWP) or the Roman era (called the "Roman Climate Optimum"). The Roman Warm Period, or Roman Climatic Optimum, was a period of unusually warm weather in Europe and the North Atlantic that ran from approximately 250 BC to AD 400. Look up the "Roman Climate Optimum" or Roman Warm Period. Weather and climate conditions through the Anthropocene are normal; that is, they are well within the range of all previous weather and climate variations. The technical terms for the warm periods are the Holocene Climate Optimum, Roman Climate Optimum, Medieval Climate Optimum, and so on. Hi Daniel, I am a bit familiar with the most … The relative warmth of average near-surface air temperatures at this time, however, is somewhat unclear. Theophrastus (371 – c. 287 BC) wrote that date trees could grow in Greece if they … And it was warmer than today's climate. This climate phase corresponds to what is known as the ‘Roman Climatic Optimum’ characterised by prosperity and expansion of the Empire, giving warmth and sunlight to crops. Harper introduces the reader to the myriad of endemic diseases that helped define Roman demography. Rome’s expansion and flourishing were linked to a climate regime known as Roman Climate Optimum, or RCO. Temperatures, however, did not get as warm as the Climatic Optimum. The more heat-loving trees as elm and linden became rarer and never again regained their dominant position in the woods. Cooler is drier; and unpleasant…so head for the warmer, easier lands around the Med; even if they were no longer as warm … Some authors suggest dry mid-Holocene conditions (Prieto 1996), while others interpret the record as evidencing a moister mid-Holocene climate (from 8500 RCYBP to 3500 RCYBP), based on the concept of "Climatic Optimum" or Hypsithermal (Iriondo 1999; Krohling 1999; Krohling and Iriondo 1999). From the broader perspective, each of the notable high points in the current 11,000 year Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than every previous high point. Between the Holocene optimum and the Roman Warm Period . Full paper. On the other hand, they may not be pleased by an apparent implication of the study. So the MWP, the Roman Warming and the LIA are pretty well understood. This work is concerned with climate change and what the author feels are its positive (yes, climate change can be positive) and negative effects in the Late Holocene. Sadly, global cooling brought both empires crashing down. Harmless symptom was actually lung cancer It was likely related to warming elsewhere while some other regions were colder, such as the tropical Pacific.Average global mean temperatures have been calculated to be similar to early-mid-20th … The Roman Empire achieved its greatest reach and prosperity in a period known as the Roman Climate Optimum. If Northern Hemisphere temperatures have been in an overall cooling trend for two millennia due to “orbital forcing” (i.e. Despite official and media claims to the contrary, there are no dramatic increases in temperature, precipitation, hurricanes, tornadoes, or any other severe weather. Roman Climatic Optimum, a phase of warm stable temperatures across much of the Mediterranean heartland, covers the whole phase of origin and expansion of the Roman Empire. This was the time of the Roman climate optimum. ... they say that "during the Iron/Roman Age Optimum between c. 200 BC and AD 50," which is better known as the Roman Warm Period, the glacier again retreated and "reached today's extent or was even somewhat shorter [our italics] than today." The author identifies 6 causes of climate change: 1) Variations in the tilt of the earth’s axis - 41,000 year cycle. Harper has a wonderful description of the ‘economic efflorescence’ of the ‘Roman Climate Optimum’. The climate of ancient Rome varied throughout the existence of that civilization. Characterized by a stable, warm, and wet climate, the RCO began in the last two centuries BC and stretched into the first two centuries AD. During the time of Roman Empire (150 BC - 300 AD) a cooling began that lasted until about 900 AD, although Global average temperature remained relatively warm until about 600 AD. Before the late 1990s, the current scientific consensus was that climate fluctuated, sometimes hotter and sometimes cooler. This work is concerned with climate change and what the author feels are its positive (yes, climate change can be positive) and negative effects in the Late Holocene. 2 left below shows how it looked there after reconstruction at that time. From 600-900 AD (The "Dark Ages"), global average temperatures were significantly colder than today. The climate change occurred at different rates, from apparent near stasis during the early Empire to rapid fluctuations during the late Empire. The post Roman Warm Period was 2°C warmer than today, new study finds appeared first on The Global Warming Policy Forum (GWPF). As a result, climate alarmists rarely even mention the Roman Warm Period, as they are happy to let sleeping dogs lie. It transpires that the height of the Empire coincided with exceptionally temperate weather (the Roman Climate Optimum) permitting the spread of population supported by food production and trade. And these effects are (and will be) truly global: The Yooper stefaan at 04:58 AM on 14 December, 2010. The rise of Rome and the empire coincided with a climate regime called, appropriately enough, the Roman Climate Optimum, from about 250 BC to 400 AD.

Firewood. The Roman Warm Period, or Roman Climatic Optimum, is a proposed period of unusually warm weather in Europe and the North Atlantic that ran from approximately 250 BC to AD 400. The Medieval Warm Period (MWP) also known as the Medieval Climate Optimum, or Medieval Climatic Anomaly was a time of warm climate in the North Atlantic region lasting from c. 950 to c. 1250. Climate alarm skeptics will be pleased to see in the chart above evidence that the Roman Warm Period and Medieval Warm Period were warmer than the late 20th century. Roman Climatic Optimum, a phase of warm stable temperatures across much of the Mediterranean heartland, covers the whole phase of origin and expansion of the Roman Empire.

Schlüchter says, “These findings call for a fundamental revision of the prevalent view of a relatively strong coverage of the Alps with glaciers since the ice age. The resulting environment would have looked fairly different from the modern world. The Roman Climatic Optimum (RCO), which Harper writes was warm, humid and stable enough to enable Rome’s development from Scipio Africanus to Marcus Aurelius, also appears in the second chapter.
