An observational estimate of transient (multidecadal) warming relative to cumulative CO2 emissions is little over half that per IPCC AR5 projections.
AR5 claims that CO2-caused warming would be undiminished for 1000 years after emissions cease, but observations indicate that it would halve.

According to NASA, the increased rate of thickening of sea ice in the Arctic is due to Global Warming.

I guess we should count ourselves lucky the world isn’t currently in a cooling phase, otherwise we might lose the Arctic icepack altogether.

“The results of this review point to the extreme value of CO2 to all life forms, but no role of CO2 in any significant change of the Earth’s climate. … Many believe and/or support the notion that the Earth’s atmosphere is a ‘greenhouse’ with CO2 as the primary “greenhouse” gas warming Earth. That this concept seems acceptable is understandable—the modern heating of the Earth’s atmosphere began at the end of the Little Ice Age in 1850. The industrial revolution took hold about the same time. It would be natural to believe that these two events could be the reason for the rise in temperature. There is now a much clearer picture of an alternative reason for why the Earth’s surface temperature has risen since 1850.”
“There is no correlation of CO2 with temperature in any historical data set that was reviewed”.

Last year’s oceanic heat wave wasn’t as destructive as one the year before, scientists said.
The Great Barrier Reef fared better during an oceanic heat wave last year than during sizzling weather a year earlier that caused hundreds of miles of corals to bleach, according to a study published Monday that suggests the massive structure may be growing more tolerant to climate change.
The report in the journal Nature Climate Change analyzed how corals along the Great Barrier fared in back-to-back mass bleaching events. The reef ― a UNESCO World Heritage Site and the largest living structure on the planet ― was cooked by overheated seawater in 2016 and again in 2017, with images of sickly white coral horrifying people around the globe.
