The
data, compiled by the World Meteorological Organization (WMO)
indicates that the signs
and impacts of global heating are speeding up. The WMO says
carbon-cutting efforts have to be intensified immediately. The
five-year period from 2014 to 2019 is the warmest on record.
Sea-level rise has accelerated significantly over the same period, as
CO2 emissions have hit new highs.
Recognising that global temperatures have risen by 1.1 degrees C since 1850, the paper notes they have gone up by 0.2C between 2011 and 2015.This is as a result of a raid rise in emissions of carbon, with the amount of the gas going into the atmosphere between 2015 and 2019 growing by 20% compared with the previous five years.
Perhaps most worrying of all is the data on sea-level rise. The average rate of rise since 1993 until now is 3.2mm per year. However, from May 2014 to 2019 the rise has increased to 5mm per year. The 10-year period from 2007-2016 saw an average of about 4mm per year.
"Sea-level rise has accelerated and we are concerned that an abrupt decline in the Antarctic and Greenland ice sheets, which will exacerbate future rise," said WMO secretary general Petteri Taalas. "As we have seen this year with tragic effect in the Bahamas and Mozambique, sea-level rise and intense tropical storms led to humanitarian and economic catastrophes."
The
report also highlights the threats to the oceans, with more than 90%
of the excess heat caused by climate change ending up in the waters.
The WMO analysis says 2018 had the highest ocean heat content values
on record
The
study underlines the fact that wherever you look on the planet right
now, the story is the same: global warming is impacting the scale and
intensity of extreme weather events such as heatwaves and wildfires.
"Climate change due to us is accelerating and on a very dangerous course," said Prof Brian Hoskins, chair of the Grantham Institute, Imperial College London, and professor of meteorology, University of Reading. "We should listen to the loud cry coming from the schoolchildren. There is an emergency - one for action in both rapidly reducing our greenhouse gas emissions towards zero and adapting to the inevitable changes in climate."
"It
is highly important that we reduce greenhouse gas emissions, notably
from energy production, industry and transport. This is critical if
we are to mitigate climate change and meet the targets set out in the
Paris Agreement," said Petteri Taalas. "To stop a
global temperature increase of more than 2 degrees C above
pre-industrial levels, the level of ambition needs to be tripled. And
to limit the increase to 1.5 degrees, it needs to be multiplied by
five," he said.
It
has become a clichéd phrase, ”extinction of the species”, but
picture a starving child on a barren dirt field— and then multiply
that a few billion times. Climate change hits the poorest people the
hardest, those living in vulnerable areas with the fewest resources
to help them adapt or recover quickly from shocks. As the effects of
climate change worsen, escaping poverty becomes more difficult.
International climate conferences are currently haggling about the
extent to devastate the Earth because if we leave most of the world's
known fossil fuels in the ground there will be milder rather than
the more extreme versions of climate change. Under the milder
version, countless more people, species, and places will survive.
It’s the best-case scenario in which we damage the Earth less.
There's
certainly no technical obstacles to transforming to a more
sustainable form of social production. The problem is that there
don't appear to be any paths from here to there that lie along the
route of profit-maximisation. The ecological crisis we are facing
today is the result of ever-expanding capitalist production for
profit. The capitalist ruling class has a vested interest in hiding
this cause of the crisis and pretending it does not exist. In the
competitive market system capitalists are forced to cut corners in
order to stay competitive and profitable — this means ignoring
concerns about the environment. In addition, corporations are
constantly using their political power and propaganda to spread
disinformation and trample over the environmental concerns of
citizens.
Capitalism
denies - or through resolute inaction effectively denies - the acute
problem of man-made climate change. Capitalism – that brought us
wars and holocausts – has been unable or unwilling to address
man-made climate change and now threatens a climate genocide. It must
be system change, not climate change. There are the real constraints
imposed by the capitalist organisation of society, which will rule
out virtually every outcome that fails the test of compatibility with
profit. The world has the technology and the ability to wean itself
from fossil fuels almost completely by mid-century. And we have the
ability to scale up solar and wind and other renewable sources of
energy. It isn't just theoretical. We've got to stop burning dirty
coal. We've got to massively deploy renewable energy if we are going
to avoid crossing those dangerous thresholds.
Capitalism
is careering the planet towards collapse. Socialists are in a race
against time, trying to build a viable socialist movement before
capitalism brings about irreparable global warming. Given the
economic laws of capitalism future climate cataclysms are looming
ahead. Socialists have set out a possible way of achieving an
eventual zero-growth steady-state society operating in a stable and
ecologically benign way. In an ecological-minded socialist society
this abuse of the environment would be impossible as the people
themselves would be in control of production — the people who live
in the community where production takes place are obviously going to
be concerned about the environment which they live in and which they
are responsible for. Methods of production that harm the environment
would be done away with and new methods would be substituted. Harmful
technologies would be abandoned. The only way to avert the
catastrophe of ecological destruction is to get rid of the profit
motive of production and give control of production over to the
people. Eco-socialism is about rational production, instead of blind
consideration for profit (which ignores concerns about the
environment, workers long-term well-being, animal welfare, etc.).
Production under socialism will take into consideration environmental
effects, availability and renew-ability of resources, human need,
etc., and develop the least harmful methods of production.
The
concept of "peak food" is relatively easy to grasp. Food
production has steadily increased since the beginning of the 20th
century, through the use of new technologies and inventions like
irrigation techniques and fertilizers. This is good, because
population growth has steadily increased over the last few centuries.
(The world's population was 1 billion in 1800 and now over 7
billion.) However, with all those technological advances, various
kinds of food production have already begun to plateau. This means
that while global production continues to increase, it's doing so at
relatively lower levels than before. The population, meanwhile, isn't
showing any signs of slowing down. That's a problem.
Recognising that global temperatures have risen by 1.1 degrees C since 1850, the paper notes they have gone up by 0.2C between 2011 and 2015.This is as a result of a raid rise in emissions of carbon, with the amount of the gas going into the atmosphere between 2015 and 2019 growing by 20% compared with the previous five years.
Perhaps most worrying of all is the data on sea-level rise. The average rate of rise since 1993 until now is 3.2mm per year. However, from May 2014 to 2019 the rise has increased to 5mm per year. The 10-year period from 2007-2016 saw an average of about 4mm per year.
"Sea-level rise has accelerated and we are concerned that an abrupt decline in the Antarctic and Greenland ice sheets, which will exacerbate future rise," said WMO secretary general Petteri Taalas. "As we have seen this year with tragic effect in the Bahamas and Mozambique, sea-level rise and intense tropical storms led to humanitarian and economic catastrophes."
"Climate change due to us is accelerating and on a very dangerous course," said Prof Brian Hoskins, chair of the Grantham Institute, Imperial College London, and professor of meteorology, University of Reading. "We should listen to the loud cry coming from the schoolchildren. There is an emergency - one for action in both rapidly reducing our greenhouse gas emissions towards zero and adapting to the inevitable changes in climate."
And
here the concept of “peak” undergoes a subtle modification,
because it no longer means “maximum production, after which yields
start to fall.” It just means “the point at which the growth in
production stops accelerating”: it’s the peak rate of growth, not
actual peak production. But even that is quite ominous, if you think
about it.
During
the latter part of the 20th century, food production grew at around
3.5 percent per year, comfortably ahead of population growth, but the
dramatic rise in crop yields was due to new inputs of fertilizers and
pesticides, much more irrigation, and new “green revolution” crop
varieties. Now those one-time improvements have largely run their
course, and global food production is rising at only 1.5 percent a
year.
Population
growth has slowed too, so we’re still more or less keeping up with
demand, but there are signs that food production in many areas is
running up against what researchers at the University of
Nebraska–Lincoln in a report last year called “a biophysical
yield ceiling for the crop in question.” Production of the food in
question stops rising, then may even fall.
Have
we reached peak food? Authors
of a new study
in Ecology and Society say “yes,” claiming our ability to grow
more food has reached its limit, despite advances in growing
technology, even as the population increases. But others say that if
we simply stop wasting food, we won’t have a problem.
Ralf
Seppelt, a scientist with the Helmholtz Centre for Environmental
Research in Germany, and several colleagues looked at production
rates for 27 renewable and nonrenewable resources, according to
Smithsonian Magazine. Using data they collected from different
international organizations, including the Food and Agriculture
Organization and the International Union for Conservation of Nature,
they “analyzed yield rates and totals over a period of time—from
1961 to about 2010 in most cases. For renewable resources like crops
and livestock, the team identified peak production as the point when
acceleration in gains maxed out and was followed by a clear
deceleration.”
In
every category, the rate of growth is still increasing — except for
wild-caught fish — but at a monumentally slower rate than
previously measured. Peak production of most food products occurred
between five and 30 years ago. Peak corn production occurred in 1985;
peak rice in 1988; peak milk and wheat in 2004.
This
means, Seppelt asserts, that these crops and many others will plateau
in growth and potentially even decline. Why? Because we have already
used all of the pesticides, fertilizers and “genetic modification”
tricks we know to increase food yields and there simply no more
tricks in the hat. “Just nine or ten plant species feed the world,”
says Seppelt. “But we found there’s a peak for all these
resources. Even renewable resources won’t last forever.”
Fertilizing soil is important, but it can only go so far. We reached
peak nitrogen, an essential nutrient to fertilizer, 1983.
Converting
forest and marshland to farmland holds some potential, but losing
more forests to agriculture is a recipe for ecological disaster.
Jonathan Foley, director of the California Academy of Sciences, said
that the trajectory is a warning but in a way, it’s good news. “It
means we will have to change how we eat and use food,” he said in
Smithsonian Magazine. He also notes that 30 to 40 percent of food
globally goes uneaten. In developing nations, this waste happens
before the food gets to market and the food spoils. In developed
nations, it occurs post-consumer.
Phosphorus
is a critical ingredient of fertilizer, and it is the eightfold
increase in the use of fertilizers that has enabled us to triple food
production worldwide from about the same area of land in the past
sixty years. At the moment we are mining about 200 million tonnes of
phosphate rock a year, and the global reserve that could be mined at
a reasonable cost with current technology is estimated at about 16
billion tonnes. At the current level of production it won’t run out
entirely for 80 years, but the increasing demand for fertilizers to
feed the growing population means that phosphate production is rising
fast. As with peak oil, the really important date is not when there
are no economically viable phosphate rock reserves left, but when
production starts to fall. Peak phosphate is currently no more than
40 years away—or much less, if fertilizer use continues to grow.
After that, it’s back to organic fertilizers, which mainly means
the urine and feces of 10 or 12 billion human beings and their
domesticated animals. Good luck with that.
Peak
soil is a trickier notion, but it derives from the more concrete
concept that we are “mining” the soil: degrading and exhausting
it by growing single-crop “monocultures”, using too much
fertilizer and irrigating too enthusiastically, all in the name of
higher crop yields.
“We
know far more about the amount of oil there is globally and how long
those stocks will last than we know about how much soil there is,”
said John Crawford, Director of the Sustainable Systems Program in
Rothamsted Research in England. “Under business as usual, the
current soils that are in agricultural production will yield about 30
percent less...by around 2050.”
The
United Nations’ Food and Agriculture Organization estimates that 25
percent of the world’s soils that are currently under cultivation
are severely degraded, and another eight percent moderately degraded.
(Even “moderately degraded” soil has lost half its capacity to
store water.) And the only way to access new, undamaged soil is to
deforest the rest of the planet.
Agriculture
overtake deforestation as the leading source of land-based greenhouse
gas pollution during the past decade. The research shows that the
recent climate-protecting gains in forests are being nearly canceled
out by efforts to satisfy the world’s growing appetite—particularly
its appetite for meat. Greenhouse gases released by farming, such as
methane from livestock and rice paddies, and nitrous oxides from
fertilizers and other soil treatments rose 13 percent after 1990, the
study concluded. Agricultural climate pollution is mostly caused by
livestock. Cows and buffalo are the worst offenders—their
ruminating guts and decomposing waste produce a lot of methane. They
produce so much methane, and eat so much fertilized feed, that
livestock are blamed for two-thirds of agriculture’s climate
pollution every year. Some countries, particularly India, have
been averse to discussing agricultural impacts during U.N. climate
negotiations—largely because they fear that the outcomes of such
talks could reduce agricultural output and worsen food shortages.
“Poor countries are not going to sit idly by and just impose
reductions in food production to meet greenhouse gas reduction
targets,” Schwartzman said.
Doug
Boucher, the director of climate research at the Union of Concerned
Scientists, says agriculture’s climate impacts could be reduced
without taking food off tables. Reducing the overuse of fertilizers,
protecting the organic content of soils by changing farming
practices, and keeping rice paddies flooded for fewer weeks every
season could all contribute to a climate solution, he said. The
biggest opportunities for reforming agriculture’s climate impacts
can sometimes be found miles from where any food is grown. Reducing
waste where food is sold, prepared, eaten and, in many cases, partly
tossed in the trash as uneaten leftovers or unsellable produce,
reduces the amount of land, fertilizer and equipment needed to feed
everybody. “Shifting consumption toward less beef and more chicken,
and reducing waste of meat in particular, are what seem to have the
biggest potential,” Boucher
said.
Global
agriculture and food production is responsible for about 25% of green
house gases (GHG) emission. About one half of ice-free land is used
for food production. The amount of GHG emission linked to meat
production is dramatically higher than for plant –based food
products. Tilman and Clark found
that
production of one pound of beef protein causes 250 times the GHG
emission as compared to the production of one pound of legume-derived
proteins. Or another way for comparison, 20 servings of vegetables
correspond to less GHG emission than one serving of beef. If the
current cultural and diet trends continue to 2050. During this
period, increase in global population by 36%, together with increase
in dietary shift towards meat consumption, will cause an increase of
estimated 80% in GHG emission from food production. This
increase in emission is equal to the total 2010 global transportation
emission. A global shift from the omnivore diet to the alternative
plant-based diet can dramatically slow down this trend. The
Scientists estimate that this global diet change with several other
changes (such as reduced wastage of fresh produce) will reduce
agriculture derived GHG emission by 30-60 % and reduce land usage by
20-30%.
People
revolt when their lives are unbearable. Sometimes material reality
creates that unbearableness: droughts, plagues, storms, floods. But
food and medical care, health and well-being, access to housing and
education— these things are also governed by economic means and
government policy. Water failure, crop failure, flooding, and more
will lead to mass migration and climate refugees— they already
have— and this will lead to conflict. Those conflicts are being set
in motion now. It is no longer peak oil but peak everything: peak
food, peak soil, peak fertilizer, even peak bees. Climate change will
increase hunger as food prices rise and food production falters, but
we already have widespread hunger on Earth, and much of it is due not
to the failures of nature and farmers, but to systems of
distribution. Almost 16 million children in the United States now
live with hunger, according to the U.S. Department of Agriculture,
and that is not because the vast, agriculturally rich United States
cannot produce enough to feed all of us. One of the events prompting
the French Revolution was the failure of the 1788 wheat crop, which
made bread prices skyrocket and the poor go hungry. Advising them to
eat cake didn’t stop the revolution.
