Sentences with phrase «long average ocean temperature»

Not exact matches

But within these long periods there have been abrupt climate changes, sometimes happening in the space of just a few decades, with variations of up to 10ºC in the average temperature in the polar regions caused by changes in the Atlantic ocean circulation.

However, certain areas in the oceans could be unusually warm and skew the overall long - term average temperature results of some of those prior studies, Shuman says.

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

The 1901 - 2000 average combined land and ocean annual temperature is 13.9 °C (56.9 °F), the annually averaged land temperature for the same period is 8.5 °C (47.3 °F), and the long - term annually averaged sea surface temperature is 16.1 °C (60.9 °F).

(1) The warm sea surface temperatures are not just some short - term anomaly but are part of a long - term observed warming trend, in which ocean temperatures off the US east coast are warming faster than global average temperatures.

«The average global temperature anomaly for combined land and ocean surfaces for July (based on preliminary data) was 1.1 degrees F (0.6 degrees C) above the 1880 - 2004 long - term mean.

But even when carbon dioxide does make its way out of the atmosphere, Earth's natural systems can release other carbon dioxide molecules that were previously stored in the oceans / land back into the atmosphere, making the full effect of carbon dioxide emissions on surface temperatures much longer than this 5 - 200 year average.

The Oceanic Niño Index, the three - month - average sea surface temperature departure from the long - term normal in one region of the Pacific Ocean, is the primary number we use to measure the ocean part of El Niño, and that value for November — January is 2.3 °C, tied with the same period in 1997 Ocean, is the primary number we use to measure the ocean part of El Niño, and that value for November — January is 2.3 °C, tied with the same period in 1997 ocean part of El Niño, and that value for November — January is 2.3 °C, tied with the same period in 1997 - 98.

Because of these restraints the oceans locally can release only a small part of the total dissolved carbon dioxide and, more importantly, when averaged over a year the amount released equals the amount dissolved, i.e. there is not net addition of carbon dioxide to the atmosphere from the oceans so long as the temperature averaged over a year remains constant from year to year.

The temperature at each land and ocean station is compared daily to what is «normal» for that location and time, typically the long - term average over a 30 - year period.

The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in average ambient global land and ocean surface air temperatures over a shorter term period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the average ambient increase in global air temperatures over such a short term is by far the least important empirical indicia of the issue.

However, over long time periods, the variation of the global average temperature with CO2 concentration depends on various factors such as the placement of the continents on Earth, the functionality of ocean currents, the past history of the climate, the orientation of the Earth's orbit relative to the Sun, the luminosity of the Sun, the presence of aerosols in the atmosphere, volcanic action, land clearing, biological evolution, etc..

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

Ocean temperatures: As meteorologist Angela Fritz observes, sea surface temperatures off the Mid-Atlantic coast were near a record high in September, and 2.3 degrees Fahrenheit above the long term average.

Because weather patterns vary, causing temperatures to be higher or lower than average from time to time due to factors like ocean processes, cloud variability, volcanic activity, and other natural cycles, scientists take a longer - term view in order to consider all of the year - to - year changes.

El Niño refers to the natural condition where ocean surface temperatures in the eastern and central Pacific near the Equator warm to levels above the long term average.

(1) The warm sea surface temperatures are not just some short - term anomaly but are part of a long - term observed warming trend, in which ocean temperatures off the US east coast are warming faster than global average temperatures.

There has not been shown to be a density variation of significance that correlates with average temperature variation (e.g, the recent high average temperature came from a small very hot area over the ocean and a small northern area, and more normal to even colder temperatures everywhere else, not global temperatures being warmer), and Solar activity has been shown to correlate very well with much of the long term (thousands of years time scale) global temperature trend.

The only possible explanation for why the average temperature of the ocean is 4C is because that is the average surface temperature of the earth taken over a period of time long enough for convection and conduction to equilibrate the entire volume.

To explore the long - term effect of future ocean conditions on E. huxleyi, we grew strain CCMP 371 in continuous culture under simultaneously elevated pCO2 and temperature: «present» ocean conditions (383 ± 43 µatm pCO2 and 20.0 ± 0.1 °C average across all generation points) and «future» ocean conditions (833 ± 68 µatm pCO2 and 24.0 ± 0.2 °C average across all generation points; see table 1 for details of conditions and carbonate system parameters).

The oceans take longer to stop warming but because of the ongoing reduction in forcing, the global average temperature reaches its maximum in not much more than a decade.

That indeed are very long - term averages and probably involve the deep oceans, which is not the case for current (2 - 4 ppmv / °C) temperature changes.
