Climate Concerns

The "CLIMATE CONCERNS" group is dedicated to discussion regarding the topic of the ever present and serious issue of changes to our climate due to the introduction into the atmosphere of human induced effects which prove harmful to the environment and which eventually may prove destructive to our planet.

Water sequestration is a viable option if there is water in the atmosphere and ground. However, when those go, so goes living things as we know them.  

There are some things I can do to slow the flow of water off the soils into ravines and rivers and ultimately into the ocean.  

*catch and store rainwater;  

*create hugelkulturs;  

*use gray water;  

*drip irrigation & soaker hoses;

The 12-month running global temperature has increased to 1.246°C above preindustrial.

Arctic Sea Ice Blog

It’s not just that we’re seeing record global heat. It’s that 2016’s jump in global temperatures may be the biggest single-year spike ever recorded. It’s that the world may never again see annual temperatures below 1 C above preindustrial averages.

Last month was the hottest April in the global climate record. Not only was it the hottest such month ever recorded — it smashed the previous record by the largest margin ever recorded. [emphasis mine]

This compares global April temperature averages. That big jump at the end was last month.

2016 had the hottest April ever recorded. Even experts were surprised.

... one expert said he believed that new data due to be released next week by the National Oceanic and Atmospheric Administration will show the last 12 consecutive months all broke records.

... the increases measured by experts around the world meant that within the last year, global temperatures had increased by 25 per cent of the total increase since the 1880s.

Mr Holthaus said he expected the record temperatures to continue for between four to six months, at which point they would begin to level out. [emphasis mine]

NASA temperature data shows last month was hottest April on record

El Nino is shutting down, and La Nina is expected by Winter. Many are holding on to La Nina's tenuous hope for relief, <sigh> afraid to look directly at the terrible changes underfoot.

Later in the year, after things got really bad, really fast, will they feel as if Mother Earth hit them upside the head? The public will claim that nobody saw the drastic acceleration of climate change coming, nobody!

Yes, CO2 based greening is encouraging. But greening is limited by water availability, and the plants contain proportionally more carbohydrate, less protein and minerals.

Interesting article on BBC about how climate change is causing a greening of many areas of the earth. THe CO2 has a fertilizing effect making plants and trees grow more lush and green - a lot more green. Interesting information.

Hopefully will get a few people's attention:

SAVE THE EARTH! IT'S THE ONLY PLANET THAT HAS CATS(More precisely, Earth will survive whatever drastic step changes happen to its climate, but keeping the planet habitable for humans and kitties would be a good thing!)

Wild weather? What wild weather?

A new study indicates that, because our current rate of CO2 increase is an order of magnitude higher than during the PETM extinction, ours will have more severe ocean acidification and ecosystems will be hit harder.

Thanks, Čenek, for the detailed explanation. I wasn’t even aware of most of that. RobertScribbler says that the strongest greenhouse effect in the Arctic happens during the long night, during which the angle of incidence wouldn’t apply. Yes it’s been far hotter and colder before we evolved, but that doesn’t reassure me. Humanity wouldn’t fare well with Permian-Triassic mass extinction temperatures.

... the correlative data we have from earlier on all says it has been far far hotter (and colder!) in the past. I'm not worried. 

Human ingenuity!

We're pretty good at solving small scale technical problems, but whole-planet geoengineering is an entirely different scale. Part of the issue is depending on fossil fuels for the energy needed to implement technical solutions. Presupposing abundant energy just comes naturally, based on our previous experience. We're used to experimenting on the bench top, where long term planet-scale side effects can be discounted.

One study, for example, looked at the possibility of pumping sea water on to the Antarctic ice shield to freeze, to mitigate sea level rise. It wasn't remotely feasible.

Apparently, it's really easy to trigger positive feedbacks to raise temperature. One CFC plant could hold back the coming ice age. But trying to go cooler is a technical nightmare.

It's easiest to grasp this asymmetry by abandoning assumptions of linear change. Our planet has had two equilibrium states, the cool/oxidizing equilibrium to which we're accustomed, and a hot/reducing equilibrium (high temperatures and acidic anoxic oceans of most mass extinction events), responding to various positive and negative feedbacks. We're are increasingly far from the cool/oxidizing equilibrium, now subject to more forcings with extreme sensitivity to initial conditions toward the inhospitable equilibrium.

It seems that so far, we've not been hot enough, for long enough yet, to lose significant hydrogen to space from a heat-expanded atmosphere. One new study suggests that a 6°C rise would produce a runaway greenhouse effect, a slow one way trip to a lifeless planet. I guess our own Venus Syndrome would be a new third equilibrium state.

Yes, Donald, the planet was hotter during the Permian-Triassic mass extinction, and we do have flora and fauna today. But 95% of then-existing life was wiped out, followed by a 5 million year long "Dead Zone" before life began to recover.
