Maui in 2009: my memory is of a lush Garden of Eden. My thoughts are with the people of the island. (Photo © 2009 mae sander) |
Every day I read more stories of the consequences of a warming world, especially consequences to the more and more fragile global food supply. I read about much irresponsible neglect and bad choices by authorities and big agriculture, and about looming disasters.
“A combination of calamities — extreme weather, Russia’s targeting of grain supplies in Ukraine and some countries’ growing willingness to erect protectionist barriers to food trade — has left food supplies more vulnerable and less prepared to absorb any one disruption, analysts say.” (source)
Throughout the world, there are such disruptions. People in many countries are suffering from heat waves, and experiencing crop failures for lack of rain or for vastly too much rain. Large numbers of refugees, especially from third-world countries, are fleeing hunger-stricken areas. A variety of food scarcities make good nutrition unaffordable for many people, including the disruptions caused by the Russian war on Ukraine as well those caused by climate issues. According to Time Magazine:
“The fingerprints of climate change are all over the intense heat waves gripping the globe this month, a new study finds. Researchers say the deadly hot spells in the American Southwest and Southern Europe could not have happened without the continuing buildup of warming gases in the air.”
Worst of all are the unprecedented disasters such as the fire in Maui, events that result from years of drought and heat waves. In Maui, specifically, after the long lack of rainfall and after the neglectful abandonment of former agricultural fields to noxious, fire-prone weeds, it seems in retrospect that such a conflagration was almost inevitable. The Washington Post reports:
“Maui is facing a compound disaster, where many different agents acted together to make the fires so horrific. As human influences on the climate and environment grow, the risk of these disasters is escalating.”
Many more consequences of global warming — signaled by this, the hottest summer every recorded — appear to be inevitable as well. I try to picture the world as it is and as it will be, and the long term is very depressing. Some people, it's true, do prefer to focus on the short term, and on a few places where a hotter planet provides a few positive effects on agriculture; for example,
“Countries in the Northern Hemisphere, especially Scandinavian countries, are currently experiencing some positive effects from climate change in terms of crop yields. This is due partly to the CO2 fertilisation effect where increased amounts of carbon dioxide in the atmosphere aid plant growth, but mostly because low levels of warming extend the growth duration of mainly perennial crops such as grass pastures, but reduce the duration of the staple annual crops, such as wheat, maize and rice. However, these effects are not permanent and will not balance the global negative effects of climate change. There is no doubt in the evidence and conclusions of more than 1,000 global and regional studies, that a temperature rise of 1 to 2 degrees Celsius will generally mean a loss in yield of a number of crop varieties, both in the tropical and the temperate regions. An increase of 3 to 4 degrees later on in this century will have very severe consequences for global food security and supply. However, it is remarkable to see that the rice plant is coping a lot better with the changes than other crops.” (source)
Concrete Examples
Will things continue to deteriorate? Unfortunately, that seems to be the most probable future. It’s a gloomy endeavor, but here are some current facts about very specific results of a changing climate:
- Oranges and other citrus crops are being devastated by weather-related disasters, for which a warming planet is a major contributor. Florida, which supplies 90% of orange juice to US consumers, is especially hard-hit: “Orange juice prices are expected to rise further in the US after a bacterial disease and extreme weather intensified by global heating ravaged this season’s crop of the citrus fruit.” Hurricanes, temperature extremes including freezing, and crop diseases resulting from the heat waves have reduced the size of the crop drastically. Brazil, California, and other citrus-growing regions have been similarly affected. (Source)
In the 1920s, oranges were a miracle, as shown by this orange crate label. Maybe oranges will be a miracle again! |
- The problem is everywhere: “A healthy diet in the UK will be put at risk by climate breakdown as European droughts shrink fresh fruit and vegetable supplies, experts have said. Fresh produce from the Mediterranean, upon which the UK is reliant, will become more expensive and harder to obtain as extreme heat causes yields to reduce, putting a healthy diet out of reach of the poorest in society.” (source)
- Field crops are affected by heavy rainfall in many agricultural regions. This change in precipitation is one of the disruptions of normal weather from a changing climate. One consequence to agricultural areas is erosion and loss of topsoil. The washed-away soil is polluting lakes, rivers, and coastal waters. Pollution and loss of oxygen in bodies of water means a negative impact on fishing, another threatened food source for humankind.
- Within a century, if unchecked, climate change will be devastating to wildlife as well as to agriculture. For example, a study by the Audubon Society predicts that two thirds (389 of 604) of North American bird species are threatened with extinction from climate change as it is currently predicted to proceed. In the Hawaiian Islands, several native species have already been almost driven to extinction as the warming climate has enabled mosquitos to live at higher altitudes, and thus transmit avian malaria to the small surviving native bird populations. Four species are particularly at risk. (source)
This Florida Scrub Jay is one of the US bird species considered to be most at risk. Climate change and many other factors play a role in the endangerment of bird species. We saw this bird at Merritt Island NWR, Florida, in 2015. |
It's a sad situation. It's heartbreaking to read about the fires in Maui, the deaths and displacement. I wonder if they can ever recover. Here in the part of Florida where we live it's been getting hotter every year and it stays hot and extremely humid longer.
ReplyDeleteI just read Jane Goodall's interviews with a journalist published as a book called The Book of Hope. Goodall says she has hope: "I do have reasons for hope: our clever brains, the resilience of nature, the indomitable human spirit, and above all, the commitment of young people when they're empowered to take action.”
ReplyDeleteI'm clinging to these.
I have just been watching a TV programme with the same theme, and the future looks very bleak. The Fires in Maui are a tragedy, and, as always, the poorest get the worst deal. This makes me glad that I am already so old. But how will the world be for future generations? I have donated to a trustworthy organisation here. Hugs, Valerie
ReplyDeleteThis has been heartbreaking to watch -- and thanks for the pointer to vetted organizations for donations.
ReplyDeleteOf small encouragement is the lawsuit that Montana youths just won, that might erode the ability of that state government to make decisions related to energy projects without also considering the role of climate change. Slight progress, perhaps, but it speaks to Deb's comment as well.
Yes, a sad post for sure.
ReplyDeleteI wonder when or if people understand and change.
Here it´s cold (and very warm soon) and so rainy. Again. The roads cannot take all the water, airport Frankfurt drowned big today. But the ground also on farms is too hard and dry to take the water as well and farmers lose their crop.
Same goes for the woods, hence all the fires.
And whilst we can work via teams & co our politicians fly the world (OK, we will fly to Perth - after 4 years, I know, not good, but there is no other way).
The situation in Hawaii is sad for sure. Such a tragedy. Your articles are so well researched and informative and you bring up so many good points. In some ways we do feel helpless as to what can we as individuals do. Perhaps we can start with reducing the demand for meat. "About 40 percent of greenhouse gases come from agriculture, deforestation and other land-use changes. Meat—particularly beef—drives climate change in two ways: first, through cows’ emission of methane, a potent greenhouse gas, and second, by destroying forests as they are converted to grazing land." taken from an article by Naomi OReskes a Harvard Science Professor. She also says,“What can I do?,” a simple and accurate answer is: “Eat less meat. It’s in your control, and you can begin right now. It benefits both you and the planet.” We could also address our high demand and consumption of Fossil Fuels!
ReplyDelete@Judee — I completely agree with you, though it’s too late for any one action to reverse the alarming trends. We reduced our meat consumption a few years ago, and this was one of several reasons why we did so.
ReplyDeletebest, mae
Hello,
ReplyDeleteIt is a sad post, the devastation in Maui,
I hope the people of Hawaii can recover and rebuild. Either there are heavy rainfalls or droughts around the world, neither are good for the crops and farmers. I do feel sorry for the birds and all wildlife so many species are threatened. I was able to see the Florida Scrub Jay at Merritt Island too, they are beautiful. Thank you for linking up and sharing your post. Take care, have a happy weekend. PS, thank you for leaving me a comment.
Thanks for sharing this eye-opening article. It's a stark reminder of the wide-ranging impacts of climate change and the urgency of taking action and offering support to those affected.
ReplyDeleteI had NO idea I was this far behind visiting. I am in catch up mode right now.
ReplyDeleteI completely agree with you on climate change. I also agree with you on the Maui fires. I saw an interview with one man who said "Don't tell people to stay away from Maui because 90% of the country is doing well." Even with the devastation, the top leaders are still pushing the tourist trade they seem to so badly need.
I stopped eating meat years ago. Looks like even the CA crops could be in trouble due to this unprecedented hurricane Hilary. Won't forget that name any time soon!
