According to the 1990 IPCC Report, an additional 0.5C global warming would need to be observed before natural variability could be distinguished with high confidence from an "enhanced greenhouse effect" due to man-made emissions. However, as an article today at Reason.com points out,
"...enhanced greenhouse warming above the noise of natural climate variability would not yet have crossed over the benchmark (+0.5°C) set by the IPCC back in 1990. Interesting."
Satellite data indicates only ~0.2C warming since 1990, considerably short of the 0.5C threshold the IPCC set for itself in 1990 to determine whether additional global warming was within natural variability.
"Climate distress is very difficult, if not impossible, to bear alone...The IPCC report is the bearer of alarming news for all on Earth. How can we best hear and respond to this alarm, caring for ourselves and others while mustering motivation and commitment for desperately needed action? The research of climate psychology tells us that rather than suppress or avoid our distress, we need to welcome it as a healthy response to the climate crisis. If we are not feeling some level of fear and grief, we are in denial. Acknowledging the myriad feelings of distress we have in response to climate breakdown is crucial for sustained action in response. Our feelings show us how much we care about our world, our communities, our lives and our loved ones. This caring is the basis for the action and change our world needs from us all right now.
