"Global Temperature in 2018 and Beyond"
http://www.columbia.edu/~jeh1/mailings/2019/20190206_Temperature2018.pdfAbstract.Global surface temperature in 2018 was the 4th highest in the period of instrumental measurements in the Goddard Institute for Space Studies (GISS) analysis. The 2018 global temperature was + 1.1°C (~2°F) warmer than in the 1880-1920 base period
The four warmest years in the GISS record are the past four years, 2015-2018.
(note: which mimics the last 4 years being the highest CO2 readings in the records too. )
The strong 2015-16 El Niño in the equatorial Pacific Ocean is more prominent in the annual 2015 map than in 2016, yet the impact of the El Niño on global temperature is greater in 2016. This is a result of the lag of 3-4 months between El Niños and their effect on global temperature.
Global land area has warmed about twice as much as global ocean, as shown in Figure 3. Linear fit to the period 1975-present yields a
warming about 1.6°C over land and 08°C over ocean.
( note: the land is where most people live, have thier homes and businesses and farms )
Thus average warming of land is about 3°F .... The warming is reaching levels at which it becomes
easier for the public to appreciate that the warming is significantIf a substantial El Niño develops, 2019 global temperature is expected to rise, although it is unlikely that the El Niño will approach the strength of the 2015-16 El Niño.
Continuing changes in global climate forcings also affect global temperature. The record 2016 global temperature was abetted by its near coincidence with a solar maximum (Figure 6).
Climate forcing by greenhouse gases (GHGs) is the dominant drive for climate change,
because it is continually increasing, but changing solar irradiance is not a negligible factor.
It has been argued that the coming Solar Minimum could be prolonged with the irradiance declining below its range so far in the era of accurate satellite data, analogous to the Maunder Minimum of 1645-1715 (Eddy, 1976)4 when sunspots supposedly were almost absent. The next few years of solar irradiance data may be particularly informative.
(
In summary - it's hot and it's getting hotter fast! The primary cause, increasing human driven GHGs are continually increasing. It's not rocket science folks. )
