4:30 am
oh, ready knows. welcome to tech told me about hackers and paralyzed me, twitter societies. computers that out were you and governments that go crazy for your data. we explain how these technologies work, how they can go wilson for and that's how they can also go terribly. watch it now on youtube. we need to talk about climate change. does that make you want to switch off? why and how can we change it? how exactly is global warming affecting agriculture around the world? the results of one study are alarming. but 1st we ask,
4:31 am
how can cattle farming be made more environmentally friendly? because cows do produce an awful lot of greenhouse gases full vis. i'm more coming up. welcome to a new edition of tomorrow today. ah, so we've all heard of the greenhouse effect, right. the x atmosphere is composed of gases in the day, the sun's shortwave rays shine through it. upon reflection on the ground, the shortwave becomes long wave radiation, which cannot permeate the atmosphere that easily. some of it gets trapped, hazing up the atmosphere. or if this didn't happen, our planet would be too cold to be habitable. but human activities release additional greenhouse gases into the atmosphere which increase the natural greenhouse effect. and the of is warming, ah,
4:32 am
one important greenhouse gas is methane for which livestock agriculture gets most of the blame. is there a way to reduce counts methane emissions? ah, an idyllic countryside seen, but something invisible is destroying the environment. cattle emit between 40700 leaders of methane every day. a greenhouse gas $25.00 times more damaging than c o 2. germany's $11000000.00 cattle generate a 1000000 tons of methane each year. does battling the climate crisis call for putting an end to cattle farming? the crew cows are incredible assets because they provide high quality products that humans eat like milk and meaning. in fact, by consuming grass that humans cannot digest into flesh. can breeding cattle be more climate friendly both in the field and inside,
4:33 am
massive cow sheds. one in the time there is no way to avoid methane because the animals are ruminant. they emit methane outdoorsman. but there's an element that could change if their feed is tweaked, emissions could be reduced to without decreasing the milk yield. the amount of methane is relative to the amount of milk produced grass has less energy than concentrated fata. so cows that craze in the paddock produce less milk than those housed indoors. but they still produce greenhouse gases. the question is, how much cost and malice and his team set up an experiment to find out? they crypt test cows with guess measuring devices with tubes have to be put into the cows nostrils. this creates a vacuum and what the cows exhale is extracted. just use this to accurately record
4:34 am
methane emissions and the test cows at keel university's organic research firm, a jersey carol there where the hardy and produce a lot of milk because they have a high feed conversion ratio. but not all grass is equal. young grass is especially nutritious in the cows digestive systems. special microbes ferment the feed, releasing nutrients, but producing c o 2 and methane at the same time with young, tender grass. the fermentation process is shorter and less. methane is produced. with mature fibrous grass, the breakdown of the stronger cell walls takes longer and is more complex. it produces more greenhouse gases. that's why these cows at keel university's organic farm, only grays on young grass. every day workers check the grass growth in the fields
4:35 am
at a certain height. it's then mowed down and used as a feed supplement for the winter. this means that the cows only ever eat the most tender shoots they haven't got. i know that we've got the birds for clover containing condensed talons in health, and then we have the small meadow button which contains hydro visible, jalen as it simply both contained tan. i letter at a challenge are best known from wine love. it gives us that for re texture on the top and 14, and they're good for ruminants because they reduce methane image. 100 income cast in malicious cows belched and exhaled about half the methane of an average german cow about 9 grams of methane per liter of milk. compared to 17 grams per liter. so farming cows with this method will reduce the carbon footprint in comparison to farming cows. in normal sheds, nadine snip covered is developing
4:36 am
a shed management system for the conventional agricultural sector. that would be very climate friendly. to feed fur high output cows consists of concentrate and mineral feed, with corn and grass silage. the mixture is made according to a precise ratio. each day they get 40 killers of grass and corn silage and about 10 kilos of concentrated feed, such as rape seed and soybean meal. concentrated feed enables a high milk yield, and like young grass is easy to digest optimally adjusted methane emissions can also be significantly reduced here, on average by 3 and a half grams per liter of milk. however, that's still more methane than grass fed cows produce. in addition, large amounts of other greenhouse gases are produced during transport, and especially during the cultivation of the concentrated feed. so why keep cattle
4:37 am
indoors at all? it's must abide, are they still? both methods are needed in germany. they're supposed pastor am stable husbandry. we want to make both methods as efficient as possible to maximize output. so the focus is on increasing efficiency and environmental compatibility. kate. but still, there's one big unresolved problem. too many animals to reach climate targets. the current number of dairy cows would have to be half what it is now. but getting rid of dairy farming completely is off the table. which nadine snick of i is happy about. man of was done. my grandparents had beef cattle on their field and nothing . and then when i studied, i did training and became even more fond of these very calm, peaceful animals, valuable on cast. and malice has also come to be a big fan of cows. right. and the crew of god, just to watch cows as they go about grazing in the field, is very beautiful. they always look like they belong to the landscape,
4:38 am
wendy. they are incredibly peaceful because she's like a giant pet. now she is rubbing herself through pity. some countries consume more grains and cereals, than meat and dairy, just 3 crumbs, the counter, 50 percent of the world's diet of corn, wheat, and rice with. but this over dependence is becoming dangerous. supply is threatened, not only by the war in ukraine model show that climate change is globally impacting harvests. more than previously believed. he got the whole thing rolling climate scientist known as eager meyer, who now conducts research at columbia university. and for nasa he's ever been rushed. i myself am surprised, our colleagues are surprised and the community is surprised. we didn't expect
4:39 am
results of this magnitude in those are stagger, irrational. other scientists are also alarmed. they think assured us via i think in the near future, we'll have to work out how to get an enough food on to our plates. ethan often tell me whether extremes are on the rise, droughts and rising temperatures are causing more and more problems for plants. in the case of corn, the decline in harvests could be felt significantly in the next 10 to 20 years. by the end of this century, harvests in some regions could even decline by almost a quarter to guide c. m. for wheat, it's different, right? wheat has regions where climate change reduces yields. but at higher latitudes, it can in fact bring game lighten even ask of inner and her gotten more c o 2 does make we grow faster, but it can also reduce its nutrient content. crops react earlier in more strongly
4:40 am
to climate change than previously thought. as shown by state of the art computer simulations. giga myers team worked for 2 years on the study for nasa and the potsdam institute for climate impact research. this is where 36 year old junior professor zant bush merkel comes in yet shifting. once we're looking at how plants respond to climate change, the goal is to keep young stable, that we're a tag as a bill and there are still too few plans that can cope well with extreme weather conditions for too long. the breeding focus has been solely on maximum yields visit the inch, heightened as we see how crucial it is to the plants, not only produce high yield, but they still produce yields, under conditions of drought and heat stress and not at reg, buying and turning. to ensure this, the researcher brings and grain varieties from around the world,
4:41 am
while barley from the middle east coast, well with drought, so smuggled crosses it with german high yield barley. the same is done with corn and wheat in the facility in hole. now. the scientist takes an unusual approach. for example, she wants to convince germans to grow more exotic crops in fitting chemo under give up to be prepared for climate change. we're also trying to establish new species. this is keen, one which normally grossly andes along kenwood is called a pseudo grain botanic lee. it's classified elsewhere, but it's used like grain and it's similar to rice. large scale farmer, gunter flung from crushed tug doesn't know anything about killa. he and his family have been running their family farm for almost 30 years, but drought in rising temperatures have repeatedly damaged harvests. frank has long been committed to finding the consequences of climate change. long glanced at lucy
4:42 am
white as the biggest farmer in the village plant. treasonous field, that's not normal, but it is normal that we're going to experience many things that we don't consider normal. now a model will have to reassess things, assembling music. frank has been doing agro forestry for 8 years. he planted trees on his corn fields, sometimes at the edge. sometimes in the middle, the trees need to be trimmed so that they don't create too much. she, eventually he harvests some of them. he also uses compost almost exclusively and has greatly reduced his use of industrial fertilizer as if he had a yo f f liquor. we had corn here in the field with the sunburn as well, and that was very unusual for the leaves. make that export said it was the o zone effect and the extreme sunlight swimming. i knew it didn't happen where the shade of the trees fell. remove all finished. the corn under the trees produce higher yields. the principle behind agro forestry isn't new. with the protection of
4:43 am
trees cropped, survive, drought better, because there microclimate improves and less water evaporates. the trees, foliage, and dead roots also create more humours. the soil becomes more fertile and can hold more water. but agro forestry is very rare here for a long time. it wasn't subsidized. back to home heine after 3 years of research sandwich. mikka now knows which kin with varieties are suitable for cultivation. i think as soon as keen, i think he one has a good chance because it's so well suited to the climatic conditions of his strategy with around the stresses and called stress on k distress. it's more difficult with other varieties, the researcher needs to speed up the breeding process, which takes about 15 years. so she and her team are looking at the plants. dna in the lab, corn leaves are shredded and dried. corn is more sensitive to water shortages.
4:44 am
researchers look for the drought stressed tolerance gene and continue breathing with those plants. mckinney technique, rudy, weedy, definitely be faster with genetic engineering than with classical breeding which i, it would probably have to be both. we'd have to be able to combine some to always reconvene ye and conan researchers also stressed the importance of watch michael and farmers like scratch or do they couldn't have included it in the current study . is a support for you on and process mass. the range of adaption measures is very important, and that's the core research that's going on here. i am anxious stuck in the blue, and it'll come down to how well and how quickly farmers and scientists can change the system. because the new study has shown that stable harvests can no longer be taken for granted. defects of climate change on agriculture can
4:45 am
already be observed across the world. we asked view is, what's your experience? how is climate change affecting farming, where you live? no herrera says that in cuba, drought and hurricanes are becoming increasingly frequent. located at you have this to say in argentina, drought in summer has become so bad. that plan started droop early in the morning and and dry periods. there are problems with pests. ah, louis canino, from period points out that there's agriculture these days and places that used to be to come before farming. andrarios are google rights that an indonesia, people who live in villages and used to practice traditional agriculture me when the rains would come and formed accordingly. now you can't predict the weather like at the moment the dry season should have begun,
4:46 am
but it's still rainy. thanks for your comments. climate change isn't just misstating for farm is it affects all of us. and yes, when virginia jeff bezos went on a 10 minute june, tend to space in july 2021. u. s. news networks dedicated to 112 minutes to covering it on that day alone. time delivery. climate change coverage, however amounted to 267 minutes, but that's over the entire year. the trouble is when it does get reported view as tend to think, it's well a bit of a downer tab about the kind of situation that of anger, rid of her grades and not many good feeling been young. and if you feel that way, you're probably not going to do much about is even though by now we all know what
4:47 am
needs to be done. so what exactly is the problem? one of the few studies on media coverage about climate change found that between 19972009 climate change coverage in 27 countries made up just point 6 percent of total reporting. it's an existential threat. and yet we're only just starting to talk about it to find out why we have to go back in time to the era of bleached hair, low rise jeans and questionable music videos. the early 2000. this was when climate change really hit the stage and being an environmental scientist back then was no easy job. no one has ever actually had to send out and say, we were lying on a substance that is sort of county wide scale destruction. oh. and it's like is massive tasks to get rid of it. and this massive consequence, if we dar kitchen just consults with climate and g o,
4:48 am
z and activists to help them get the message across climate scientists were and law charged with telling the world some really bad news. and it's also complicated to explain what we tend to know about climate change is in the form. the tables are complex, figures and numbers that are difficult, or the only person to relate to suzy wing has a background in environmental psychology and works on how we can communicate climate change better, give less speaking about timeline, so to write a very fine, distant pasta time teacher, take the latest report by the i, p. c. c, the intergovernmental panel on climate change. it's the most detailed look at the state of the earth. but the summary is 40 pages long and stops like this. lots of
4:49 am
big words, certainly not light reading. so most people don't have access or time to research the science on their own. here's where the science communicators come in, for example, and joe's or journalists. but it's literally her job to know this stuff. and to be on top of all the terminology there's so many back here back hanks who want to do this, but they don't even have the knowledge. there is better to cover this topic, right? sure. well from lagos, nigeria reports on climate change. they don't have to generally, we can cover this in a way that is accurate. no way that is simple for people to understand. and in a way that is stable even when there are enough journalists, climate reporting is still tough. a recent oxford study found these common barriers . climate change happens slowly,
4:50 am
but the new cycle is fast. the topic depresses audiences. the covering, it requires money for travel and specialized reporters use pressure from media buses and advertises to cover other topics. all this means the topic is under reported, and that little reporting also used to be full of missing information, according to a landmark paper published in 2004. it was due to the pursuit of balanced reporting . print media often gave equal credence for space to relevant experts or scientists, as well as climate deniers or skeptics that were representing outlier views. lucy, mcallister, studies the communication of environmental issues and is lead author on a recent paper on the accuracy of climate science reporting. so this was seen on
4:51 am
early 2000 and hugely misleading to the general public. 99 percent of scientists agree on climate change, so it's inaccurate to give all viewpoints equal weight. the research shows that climate change information is now mostly accurate. so is the issue resolved. the climate debate has shifted or transformed, emerged in different ways and more subtle discourses, academic literature. it's not as discourses of delay groups who tim years ago were saying, i'm general real. what we're saying now is that the energy transition is too expensive, and these discourses are repeated everywhere from politicians to companies. others include individualism, you are responsible that is your carbon footprint. technological optimism, future technologies will save us. fossil fuel solution ism fossil fuels are part of the energy transition and the most common,
4:52 am
all talk little action you have will be the world's 1st climate neutral continent. by 2050, be carbon neutral for the decades. political leaders and corporations make these promises, but don't follow through on them. and as a journalist, it's hard to find the middle ground here. solutions can be expensive. some countries continue to need fossil fuels. individual choices do make a difference. if we don't mention these aspects, we're in danger of being labeled climate activists and ignored. and what about the viewers readers and listeners? the situation we're in is so huge. it's just too complex for our is to fathom. we can't see it, we can't smell it. to it it's, it's not an easy visible enemy. and the most publicized climate victims are super hard to grasp. we're talking about how our gracious i melt
4:53 am
in. that's not something that someone in the glass is really going to care about. we naturally value what's near us more than something far away. this phenomenon is called discounting. so support for climate action decreases due to what's happening around us, like a cold winter, or low gas prices. and talking about all this in the 1st place, probably not going to make you feel great. when you can see that something is threatening to push it around seating the weight of his other myself. and that's not the only way your brain avoids these issues. let's say you know, meet is bad for the environment but you eat it anyway. these conflicting beliefs that lead to cognitive dissonance, which is the discomfort from internal conflict. 5 you either change your behavior or just rationalize your choice. and that's where we come back to the huge complex
4:54 am
nature of the problem. it seems like on our own, we can't make a difference. i think i could do more. of course we all should do more. can we do enough actually, right now i realize that i haven't thought about that before, but i know that much and i'm hard to be aware of other things to do and other sometimes i think it can be a little bit overwhelming because you're kind of powerless so what should change? let's start with the science climate science needs to be more accessible and also easy to comprehend. more scientific publications need to be open, access and complicated topics need to be more relatable. carrying about climate since means recognizing that climate change affects if other things that you care about, you're more likely to be interested in a study about health, housing, or food than insects dying out. luckily or not,
4:55 am
climate change impacts all of these areas. and more. same goes for climate reporting, it would help if it were more integrated with other topics and connected with our everyday experiences. even talk to people in the go and say, oh, have you feel that the sun just seems hotter of these past years? they can immediately connect for that and then you can started to like expand derek, your scope of knowledge and. ready that is why it's happening. this place is the science in context. another example is the human lifespan over a graph of the earth's warming. context also helps people understand the complexity of the issues. which in turn, paved the way for a focus on the solutions rather than the problems. but this shift reduces our impulse to push the topics away and makes people feel more engaged. focusing on
4:56 am
collective power over individual responsibility can also help. but perhaps most importantly, we need to talk more about the topic. that's it for this edition of tomorrow to day d. w signs show you again next week until then state curious about the world around he combined with ah ah ah
