Sentences with phrase «than average temperatures off»

Not exact matches

During the Eocene, the concentration of carbon dioxide in the atmosphere was more than 560 parts per million, at least twice preindustrial levels, and the epoch kicked off with a global average temperature more than 8 degrees Celsius — about 14 degrees Fahrenheit — warmer than today, gradually cooling over the next 22 million years.

If they continue to die off, as they did in 1999 and 2003 when temperatures were 3 to 4 °C warmer than average and summer layers lasted longer than usual, fish and other sea life that depend on them will decline too, the team say.

As of Feb. 14, 2016, the latest ocean computer model shows colder - than - average water temperatures off the South American coast from Ecuador to Panama.

As average temperatures at some plover nesting grounds have been inching up in recent years, the researchers found the mother and father bird have to switch off incubation duties more frequently than usual.

(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.

Would the steady rise after 1000AD imply that the global average temperature may have been at a fairly stable «high» until about 1400, rather than dropping off after a short medieval peak?

A couple of years ago, when it was starting to become obvious that the average global surface temperature was not rising at anywhere near the rate that climate models projected, and in fact seemed to be leveling off rather than speeding up, explanations for the slowdown sprouted like mushrooms in compost.

-- Ocean temperatures were 9 degrees (5 degrees Celsius) higher than the 30 - year average off the coasts of Greenland.

The average temperature in the first six months of 2016 was 1.3 C warmer than the pre-industrial era in the late 19th century, according to Nasa — remarkably close to the 1.5 C target agreed by the world's governments at the Paris climate talks to attempt to stave off the worst effects of climate change.

You can then easily read off how much monthly temperatures deviate from that average, which is called the temperature anomaly; if a month is colder than usual for that month in the data, that shows up as a negative anomaly.

The result is a levelling off of temperatures at a new, warmer average as cold days» temperatures rise towards the temperatures of warm days faster than the warm days themselves increase in temperature.

(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.

Then there is the off - the - shelf case that uses currently available technologies to reduce greenhouse gas emissions as rapidly as possible along a continuum between the current level and up to 560 parts per million (ppm), twice the preindustrial level, that produces average temperatures between 3 and 4 degrees higher than preindustrial levels depending on how rapidly the greenhouse levels can be brought down.

All scenarios under current federal authority and announced state plans show the United States far off the pace of reductions the IPCC suggests are necessary by mid-century to prevent average global temperatures from increasing more than 2 degrees Celsius.

Instead, maybe it'd be a lot of general uncertainty, and various difficult - to - plot proxy constraints (e.g., «in Arrow Valley, rainfall and average temperature never moved more than 38 % off this 2 - dimensional curve in (rain, T) space»), and perhaps a few clear fluctuation constraints (e.g., freezing the Thames), and some suggestive fluctuation constraints (like from proxies that can easily be weighted to look like the MWP).
