Levels go up and down slightly each year because the Northern Hemisphere has more vegetation than the Southern Hemisphere, and plants take in carbon dioxide during the summer and then release it again in the winter.

In his Figure 5 under a section entitled «A New Northern Hemisphere Summer Temperature Record» he shows that the mid to late 20th century temperature as determined from tree ring analysis is far warmer than any period in the past that his analysis includes (this only goes back to 1400 ADIn his Figure 5 under a section entitled «A New Northern Hemisphere Summer Temperature Record» he shows that the mid to late 20th century temperature as determined from tree ring analysis is far warmer than any period in the past that his analysis includes (this only goes back to 1400 ADin the past that his analysis includes (this only goes back to 1400 AD).

Scotland's high position in the northern Hemisphere means that it has longer daylight hours than other areas of Britain during the summer and shorter days during the winter.

Other than the tropical regions Australia has four seasons, but as the country is located in the southern hemisphere they are reversed, so December to February is the height of summer, June to August the depths of winter.

Although July falls during the summer for the northern hemisphere, temperatures in Belize are not much hotter than the rest of the year.

During summers, in the northern hemisphere, despite the cars and air conditioners, the world sucks in far more co2 than it makes.

(apparently the southern hemisphere CO2 air concentration actually follows the northern one by dropping several ppm in Nov - Apr (southern summer), rather than the seasonally imposed one in the north where it drops ~ 5ppm in the winter due to no photosynthesis.)

If this is correct, than sea ice will be much greater this summer than in recent years because northern hemisphere temperature anomalies have been low this winter.

This intensification has resulted in significantly greater global summer monsoon rainfall in the Northern Hemisphere than predicted from greenhouse - gas - induced warming alone: namely a 9.5 % increase, compared to the anthropogenic predicted contribution of 2.6 % per degree of global warming.

While temperatures in the Northern Hemisphere were warmer than average during the summers, the tropics and areas of the Southern Hemisphere were colder than average which comprised an average global temperature still overall lower than present day temperatures Northwestern North America had peak warmth first, from 11,000 to 9,000 years ago, while the Laurentide ice sheet still chilled the continent.

The summer - winter changes in insolation are much larger than those due to human - induced greenhouse gas changes; the seasonal change is mainly in the visible part of the electromagnetic spectrum while the greenhouse gas forcing is in the infrared; the greenhouse gas influence is global while the seasonal changes are opposite in the two hemispheres; and we have a much longer history of observing the seasonal changes, so a more or less correct prediction can be made empirically, without any physical understanding.

For the Northern Hemisphere, on the other hand, the decrease in winter maximum has been about 42,000 km ^ 2 / yr and the decrease in summer minimum has proceeded at about 81,000 km ^ 2 / yr — rates dramatically greater than in the south.

Is NCEP reanalysis more accurate (lower bias and RMS) in summer (JJA) than in winter (DJF) in the stratosphere and troposphere of the northern hemisphere?

One reason for this is that «global temperature» varies significantly over the months of the year due to seasonally varying Earth / sun geometry and the greater land mass in the Northern Hemisphere, so that any global average of absolute temperature, not anomalies, will be considerably higher in NH summer than SH summer, and this will be true even in an unchanging climate.

The North American Multi-Model Ensemble (which does, in fact, exhibit pretty good predictive skill for summer temperatures in the American West) is presently suggesting a high likelihood of a warmer - than - average summer in California (and, indeed, most of the Northern Hemisphere).

Cherrypicking is a vital tool in their armoury, so let's illustrate it with a working example: how to make Northern Hemisphere summers colder than winters.

We now know that conditions at this time were probably warmer than today, but only in summer and only in the extratropics of the Northern Hemisphere.

So when summer hits in the southern hemisphere, one sees more CO2 in the atmosphere than when it is summer in the northern hemisphere.

The direct radiative forcing (DRF) is strongest in the Northern Hemisphere summer when the insolation is the highest although different seasonal cycles of the sulphate burden from the chemical transport models result in maximum global mean radiative forcings ranging from May to August (e.g., Haywood and Ramaswamy, 1998), the ratio of the June - July - August / December - January - February radiative forcing being estimated to lie in the range less than 2 (e.g., van Dorland et al., 1997) to > 5 (e.g., Penner et al., 1998b; Grant et al., 1999) with a mean of approximately 3.3.

Arhennius correctly predicted approximately how much the temperature would go up, greater increase in winter than summer, greater increase at night, greater increase in the Northern Hemisphere (especially the Arctic) and greater increase over land than water.

Summers on the Norwegian archipelago of Svalbard are now warmer than at any other time in the last 1,800 years, including during medieval times when parts of the northern hemisphere were as hot as, or hotter, than today, according to a new study in the journal Geology.
