Farming vegetables causes less greenhouse than livestock production. Climate experts say people should eat more vegetables for better health and for slowing greenhouse gas emissions that cause climate change.

Consider that studies show farming and other land use account for about a fourth of all greenhouse gas emissions, and about half of methane gas emissions are released into the atmosphere from cattle and rice fields. Meat in particular has more greenhouse gas emissions. 

Climate experts say the nutritional value of wheat grown in higher CO2 areas is 6% to 13% less for protein, and 5% to 8% less for iron. Another problem aggravating the situation is that drought has grown 1% a year between 1961 and 2013, IPCC researchers have found. This is a result of the growing climate change issues. Drought and nutrition is a major problem in India and Africa.

The U.S. government's National Climate Assessment report in November 2017 says observational evidence proves that human action is the main driver for climate change. It warns of sea levels rise as high as 8 feet by the year 2100. It shows damage from climate change that is already happening from a rise in the U.S. by 1.8 degree Fahrenheit of global warming since 1900. Trump has announced withdrawal by the U.S. from the Paris Climate Change Agreement that would cut U.S. greenhouse gas emissions by 26-28 percent by 2025 compared to 2005 levels. The Trump administration is relaxing rules by the EPA that would have contributed to the goals of the Paris Agreement.

California, New York and Washington are  three states, with 30 other cities in the U.S., and 100 large businesses, forming the U.S. Climate Alliance, saying they will  follow the Paris agreement on climate change. Former Mayor Bloomberg of New York City is organizing the effort, and he says in the U.S. it is cities, states and businesses that actually do the work of reducing emissions, not the federal government. Bloomberg said: "The fact of the matter is Americans don't need Washington to meet our Paris commitment." Governor Jerry Brown of California says the response will be for California and other states to set even bolder standards for reducing emissions.

Report on Climate Science put out by the US Energy Department in 2025 questioning the severity and impending nature of climate change effects. It is challenged by scientists who believe in the severity and impending nature of climate change, quite the opposite. Koonin, a Fellow at the Hoover Instituion at Stanford describes the work and its conclusions. He says the research is peer reviewed and looks at 200 years of climate research. Some of the conclusions- That climate change models claiming catastrophic situations are ultra sensitive and lead to extreme scenarios.  It talks about climate variability, and model deficiencies, data limitations. And says data for climate over continental US show no long term trends for extreme weather events. Global sea level rise of 8 inches since 1800 is not disputed but it says US tide gauge data shows no long term acceleration in warming globe.  On one point there has been agreement even in the Biden administration- what the US does to cut emissions will little effect the global changes in warming- because of coal use by China and India defended as needed for electricity for two billion people, an essential need. Thus the desire for a calculated tradeoff which lets the US take advantage of its abundance of oil and gas to reduce the cost of living for ordinary Americans, also an essential need. Because of the declining cost of natural gas vs coal, coal is in gradual phase out, and declining cost of solar means Germany, China, India are making the shift to solar, and nuclear energy provides another option. The difference is that the DJT administration is taking government out of the effort and letting the private sector work out building of renewable sources. Government is not always the answer as electric cars are likely to make more gains in 2026 than under the Biden administration because of VW, Mercedes, BYD, Ford and GM coming up with cars that can do close to 500 miles on one charge and the cost of an EV down to about $30,000 to $40,000. ...

Cost to reduce global warming to 1.5 degree centigrade goal set for climate change is estimated to cost $131 trillion. $116 trillion would be for electrification, new technologies, rebuilding electricity networks, efficiency. $24 trillion needs to be redirected quickly from fossil fuel investment to investment in reducing climate change by investing in other energy sources. 

The danger lies in 2.7 degree centigrade warming of the planet by the end of the century.

This report in the New Yorker provides a good glimpse at the problems of global warming and limiting climate change goal of 1.5 degrees centigrade. Sally Ann Ranney co-founder of the American Renewable Energy Institute answers questions from the New Yorker magazine. Limiting climate change warming of the planet to 1.5 degrees centigrade by 2100 is a goal enshrined in the Paris Agreement. In the absence of this the global warming would be 2.7 degrees centigrade by 2100. For this 1.5 degrees centigrade goal to be reached fossil fuel use and carbon emissions have to be cut by 50% by 2030 and 100% by 2050. 

The ice pack in the Arctic is part of a planetary cooling system and its accelerated melting is a good sign of the danger the planet faces. Ranney answers a number of these questions.

The global stocktake was set for 2023 at the 2015 Paris Climate Accords. This measures the progress towards limiting climate change warming to to 1.5 degrees rise in temperatures. The 2023 stocktake at COP28 Dubai shows the goal is elusive and the earth is at warming by 2.5 degrees Celsius, with the climate change action of industry and public participation flagging. The pandemic has worsened the financial ability of poorer countries to handle the transition to clean energy, even as it has caused serious floods and fires. The major oil companies are also not investing as needed.

Each year the amount of forestedd land that is cleared- mainly for cattle needing pasture land- releases the equivalent of greenhouse gas emissions of 600 million cars. Since 1961 methane gas emissions from cattle has increased significantly. This is one of the findings in a report published by 100 climate change experts for a UN body. Loss of peatlands in places like Indonesia is also a problem.  A half a billion people already live in desert. And land is being lost a hundred times faster than it is forming due to changes in weather patterns.  People migrate when weather fails as has happened for central American farmers migrating to the U.S. creating social and political problems in North America. A major issue in climate change is agriculture.  Increasing the productivity of land, reducing food wasted, persuading more people to eat healthy vegetables and less meat, reducing land lost to desertification, erosion and seas, are all actions that can be taken now say these 100 experts from 52 countries meeting in Geneva. The IPCC or Intergovernmental Panel for Climate Change does these reports to give people some idea of what actions to take to reduce the impact of warming that threatens livelihoods of millions especially in Africa and India, as well as other parts of Asia and Latin America. Developed countries are likely to feel the impact from migration which is dividing their societies politically and socially. As one expert from Aberdeen puts it people don't just stay where they are when drought conditions hit their areas, they migrate. ...

Efforts by China's climate envoy at Glasgow COP26 and US envoy John Kerry to build cooperation between China and the US on climate change. This happens at the end of COP26 talks and after president Jinping missed the Glasgow summit. Xie says China will work towards "concrete plans" for "finalization of the Paris Agreement rulebook." The US China agreement is not specific on details but includes arranging regular talks, and also a focus on curbing methane gas emissions which can produce immediate results in reducing global warming. The US and over 100 countries signed an agreement on methane gas emissions control.

Scientists at Haifa, Kyoto, and at WWA the World Weather Attribution Group say climate change is a cause of the sudden floods in Libya which swept parts of Derna into the sea. It rarely rains in September in the Mediterranean and it is warming 20% faster than other oceans changing weather patterns. Sea surface temperatures near the coast of Libya was 81.5 degree Fahrenheit exceeding the 78.8 degrees when storm systems develop. Kyoto scientists say the two dams that burst had seen sediment accumulate over time reducing the capacity to retain flood waters, and setting loose a torrent of mud when the dams failed. Wars and lack of upkeep of the dams combined with climate change created the flood damage in Libya.

March 2022 was the hottest month in India for 122 years since records began. It was also extremely dry. Scientists say such a heat wave with temperatures reaching 50 degrees centigrade in April and May in India, "would have been extraordinarily rare without the climate crisis." They say it has a 1% chance even with current global warming.

Svenja Schulze brings new hope and dynamism to Germany's Development Ministry. As head of the Development Ministry she brings international experience in fighting climate change as SPD minister in the last government heading the climate change related Environment ministry. There she launched the climate protection package measures aimed at making Germany climate neutral by 2045. She now heads a ministry with a budget of $13.5 billion (12 billion euros). She wants to cooperate better with the Global South with an effort to tackle poverty and help developing nations. After the shocks of the pandemic this is an essential and important task. Her predecessor as Development minister Heidemarie Wiezcorek-Zeul, SPD minister 1998-2009 says the ministry needs clout in decisionmaking and for this it is important that the Development ministry is separate and an independent entity not lumped in with the Foreign Office as in Britain. That would be quite disastrous she says.  Climate change issues are also seen as development issues and about poverty reduction. This is a useful point that Mr. Modi was trying to make as he addressed the COP26 Summit- that climate change has to be done in the overall context of mitigation, that climate change control is part of poverty reduction and brings in new opportunities when done this way. Examples are zero budget farming, and solar energy as low cost energy for rural areas in India. Here Schulze talks to employees at the Ministry and tell them "We must all strive to make a good life possible for everyone in the world, That may sound overly emotional, but it is our aspiration."  Martina Schaub, chairwoman for VENRO whivh represents 140 private and church development organizations in Germany sees Schulze as a sign of optimism. The need is great particularly in the weak health systems of many countries. It is a sign of hope, and of the new Germany under Schulz. ...

Queen Elizabeth's voice is heard on the microphone before a meeting of the Welsh parliament: "We only know about people who are not coming to the Glasgow Climate Change Summit, its very irritating that they say but they don't do." China had promised to peak coal use by 2030, and help achieve reducing global warming under Paris summit goals. This looks like a remote possibility today as China faces blackouts and factory closings from reducing coal use.

The Guardian looks back at 2023 and covers the work of scientists from US, Germany and Brazil showing the damage. NASA scientist James Hansen tells The Guardian that with the current stage of politics and inaction on climate change young people in the world need to take over. Scientists at the Japan Meteorological Agency measured temperatures at 0.53 degrees centigrade higher than the global average 1990 -2021. This was higher than the previous high reached in 2016 of 0.35 degrees centigrade. Over the long term the world is considered to be 1.2 degrees hotter than preindustrial times, by experts. Included is the report "Hothouse Earth" by the Potsdam Institute of Climate research and other experts on the speed of the global warming.

PM Narendra Modi addressed a World Bank organized "Making it Personal: How behavioural change can tackle climate change" conference. Modi called it part of democratising the battle against climate change. "Simple acts in daily lives are powerful, there will be a very positive impact on the environment. The people of India have done a lot in this matter in the last few years." "People driven efforts improved the sex ratio in many parts of India. It was the people who led a massive cleanliness drive. Be it rivers, beaches or roads, they are ensuring public places are free of litter. And it was the people who made the switch to LED bulbs a success. Nearly 370 million LED bulbs have been sold in India. This helps in avoiding 39 million tons of carbon dioxide emissions every year." The Mission Life Modi introduced with the Secretary General of the United Nations has achieved much in India- "The farmers of India ensured the coverage of nearly seven hundred thousand hectares of farmland by micro-irrigation. Fulfilling the mantra of 'Per Drop More Crop', this has saved a huge amount of water. Under Mission Life our efforts are spread across many domains such as: Making local bodies environment-friendly, saving water, saving energy, reducing waste, and e-waste, adopting healthy lifestyles, adoption of natural farming, promotion of millets." ...

Everything you might want to know about coffee, where it comes from, how cultivation is changing with climate change and higher temperatures, and the effort to map the coffee genome. With higher temperatures the farming of coffee moves to higher altitudes in coffee growing countries in the tropics, but it is easier to cross breed the 124 varieties to produce a plant that can withstand the change in temperatures and one that can resist fungus.  A coffee fungus and higher altitude rains destroyed much of the crop in Central America including Guatemala. This led to increased migration to Mexico and U.S. of farmers leading up to Mr. Trump's plan to have the National Guard of Mexico police Mexico's border with Guatemala.  Coffee is a sensitive plant and needs cooler weather and water which is found more in the tropics. Growing it in California or in Italy makes it very costly leading to Frinj coffee being sold in California at $16 a cup. Climate change could reduce the area where coffee can be grown by about 50% in the tropical countries from South east Asia to African countries such as Kenya, Uganda, Tanzania and Ethiopia, and in south America Colombia and Brazil, says Climate Institute, Washington DC based climate change experts.   ...

The Paris climate change agreement involved 195 countries. Agreed to on December 12, 2015 it was seen as a major step forward to limit global warming to 2 degrees celsius or 3.6 degrees Fahrenheit. Progress has been slow in taking action since then. Because of covid 19 the Glasgow conference was cancelled. Hope stems from the goals set for carbon neutral economy of Japan, the EU, UK, China, and the U.S. as it enters the agreement after withdrawing.  Much will depend on action taken as the pandemic has pushed economic goals of recovery to the forefront. As India has shown in renewable energy, particularly in solar energy targets and bold vision, there is a lot that can be done by each country acting on its own without the hype of the agreement. India now sees huge opportunities in solar energy because it is cheaper and pollutes less than coal. This is a game changer that comes from investing in new technologies and taking advantage of India's abundant access to sunny weather and the lower labor and other costs. ...

Kernza is a new kind of grain from wheatgrass that is environmentally friendly being tried out by Kansas farmers in the US. A single seed of Kernza grain grows into a plant that provides grain year after year without the need for costly fertilizer, more water and energy. It forms deep roots that store carbon, and grows alongside other crops and provides wildlife habitat.  In this report from Washington Post an artisan baking company is shown baking Kernza and wheat grains bread.

Climate change makes Kansas summers much hotter and drier, and makes rainstorms more intensive, says this report. Land Institute ecologists say traditional farming is carbon intensive and alternatives are needed. Kansas had some of the richest soil in America say ecologists, but it is being degraded at a rapid rate. As America's breadbasket state a lot needs to be done to enrich and restore Kansas agricultural land.

U.S. president Trump's executive order reversing parts of the Clean Power Plan of president Obama may extend the life of older coal powered plants, but overall it is unlikely to change the shift away from coal for the U.S. utility industry. It will do little to reverse the market forces that are leading to a shift to natural gas for the utility industry with the increasing availability of natural gas. In this WSJ report Cassandra Sweet cites Duke Energy Corp. CEO Lynn Good, who says natural gas for Duke will be the leading fuel followed by coal by 2026, and natural gas now makes up 28% of its mix with coal at 34%. He says a $11 billion ten year investment in natural gas and renewable energy will go through regardless of what the Trump administration does because of the economics- the declining price of renewables, the competitive price of natural gas. Companies are loath to base their long term plans on changes in administration as they see the economics dictated by advances in technology, and the general sense that cleaner energy is here to stay for the long run. Already in the U.S. 34% of total power supplies are from natural gas and 30% from coal for 2016, according to the U.S. Energy Department. This may change slightly as coal is used where it is economical and makes sense without the carbon rules, yet the long term trend is clearly towards natural gas. ...
