Orbital variations.
Slight variations in Earth's orbit lead to changes in the seasonal distribution of sunlight reaching the Earth's surface and how it is distributed across the globe.
There is very little change to the area-averaged annually averaged sunshine; but there can be strong changes in the geographical and seasonal distribution.
The three types of orbital variations are variations in Earth's eccentricity, changes in the tilt angle of Earth's axis of rotation, and precession of Earth's axis.
Combined together, these produce Milankovitch cycles which have a large impact on climate and are notable for their correlation to glacial and interglacial periods, their correlation with the advance and retreat of the Sahara, and for their appearance in the stratigraphic record.
The IPCC notes that Milankovitch cycles drove the ice age cycles, CO2 followed temperature change "with a lag of some hundreds of years," and that as a feedback amplified temperature change.
The depths of the ocean have a lag time in changing temperature (thermal inertia on such scale).
Upon seawater temperature change, the solubility of CO2 in the oceans changed, as well as other factors impacting air-sea CO2 exchange.
This is the most common type of heat detector.
Fixed temperature detectors operate when the heat sensitive eutectic alloy reaches the eutectic point changing state from a solid to a liquid.
Thermal lag delays the accumulation of heat at the sensitive element so that a fixed-temperature device will reach its operating temperature sometime after the surrounding air temperature exceeds that temperature.
The most common fixed temperature point for electrically connected heat detectors is 136.4°F (58°C).
Technological developments have enabled the perfection of detectors that activate at a temperature of 117°F (47°C), increasing the available reaction time and margin of safety.
This type of technology has been available for decades without the use of batteries or electricity as shown in the picture. 
Bathytroctes is a genus of slickheads that occur in the depths of the oceans. 
In economics, an outside lag is the amount of time it takes for a government or central bank's actions, in the form of either monetary or fiscal policy, to have a visible effect on the economy.
Its converse is inside lag. 
Debt-Lag is a condition which results from overuse of one’s credit card or other forms of credit while travelling.
The debt itself can refer to the amount spent in the lead up to travelling, during the trip and any unexpected costs which come about from that trip, such as cross currency conversion fees and foreign ATM access charges.
The condition of debt-lag may last months or even years after a person’s trip is complete, as long as the debt accrued within the travel period is still outstanding.
It is recommended that sufferers of debt-lag seek treatment as soon as possible to avoid paying exorbitant fees in interest charges.
The term debt-lag is similar to jet lag in that both have to do with travel, however travellers can be affected by debt-lag without leaving their time zone.
Jet lag refers to the condition sustained by the body after rapid long-distance travel which requires days of adjustment upon return.
Debt-lag works in much the same way as it refers to a traveller’s need to adjust upon return as well, except it is more directly related to the traveller’s financial situation than their biological one.
