See what Dec 2015 to Feb 2016 looked like, temperature-wise:

2016 started off way hotter than 2015. A sudden jump like this is called a step change. If you expect we'll now cool off to our previous decadal average, forget that. We've "leveled up". 

The current warming surge amounts to what’s called a step change — a practically instantaneous shift in our planet’s climate.

This sudden shift in temperature has arrived because of a confluence of events: Long-term global warming, the multiyear effect of El Niño, and extreme weather — including persistent heat waves at the regional scale.

The major cause of February’s exceptional warmth is global warming,…

El Niño can’t explain all or even most of the current warming spike — especially the warmth in the Arctic.

El Niño warming probably explains about 0.2 degrees Celsius of the current global surge, according to a modeling study from the Met Office (the U.K.’s national meteorological service).

Based on the Met Office’s estimates and my calculations, 2016 will probably be around 1.1 to 1.5 degrees above the 1850-1900 average. An annual breach of 2 degrees could happen as soon as 2030, according to climate model simulations,…

According to a five-year prediction from the Met Office, global temperatures may fall slightly over the next year or two, as the El Niño wanes and temporarily cooler ocean temperatures associated with La Niña take hold. But global warming will make that respite brief: 2018, 2019 and 2020 will likely be warmer than 2015, and the warming trend is expected to continue long after that. Sixteen of the 18 years that followed the last big El Niño (1997-98) were warmer than 1997. [emphasis mine]

When Will The World Really Be 2 Degrees Hotter Than It Used To Be?

Step changes also happen in other climate issues, such as the rate of sea level rise. Sudden jumps in the rate of melt indicate a tipping point was passed, and new self-reinforcements have kicked in.

Doubling times in non linear events often don’t fit a pure exponential curve — instead tending to follow a series of spikes and recessions with major transitional events coming at the end of any ‘curve.’ [emphasis mine]

Our path ahead: major transitional events kicking us into new regimes of change we'll hate.

If returning "to earlier religious practices" includes believing there are a heaven and hell, that god is just and will punish the wrongdoers, and we will be reunited with loved ones, even pets, then I will have none of it. 

Joan, you overlooked the context.

Did “the wise ones of the Native Indians” have a heaven and hell, et cetera?
