Scientists attribute the drought’s severity to climate change, deforestation of the Amazon rainforest, and the La Niña weather pattern. After a decade of dry conditions, a drought in Brazil is straining the country’s economy, energy systems, and environment. Reservoirs are dwindling, causing major deficits in hydroelectric power.
One tipping point scientists have on their radar is the Atlantic Meridional Oceanic Current, a stream of water running northward up the Atlantic whose flow depends on a precise temperature gradient. Warming ocean temperatures could cause this current to slow down or collapse altogether.
This is a pretty clear illustration of how sea level starts to rise slowly; but in the long run, sea-level rise caused by fossil-fuel burning and deforestation in our generation could literally go off the chart and inundate many coastal cities and wipe entire island nations off the map. But first things first. Observed Past Rise.
Its location between two oceans, as well as its latitude and topography significantly increase Mexico’s exposure to extreme hydro meteorological events.” Mexico’s climate commitment for 2030 under the Paris Agreement calls for cutting emissions 22%, cutting black carbon by half, and achieving net-zero deforestation.
During last November’s COP26 climate change conference, the president of Costa Rica, Carlos Alvarado, signed an agreement that will see US$20 million flow towards the conservation of the country’s forests, funds earmarked to increase protection and help avoid deforestation. Debt-for-nature swaps in Costa Rica.
Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) The argument has been made that the ‘cold blob’ might not be caused by an AMOC decline but by heat loss at the ocean surface. We argued in Caesar et al. The reanalysis data show the latter is the case.
Two reports published in the US look seriously at the practicalities and responsibilities of altering the ocean to tackle the climate crisis. Two recent developments aim to clear a path for testing these controversial methods in the ocean. The ocean as a carbon sink. Photo credit: Daniel Poloha / Alamy. By Olive Heffernan.
In particular, he said, “reliance upon coal, on the other hand, could aggravate the ‘greenhouse effect,’ whereby excess carbon dioxide (which accompanies coal burning) traps heat inside the earth’s atmosphere, thus possibly melting the icecaps and raising the level of the oceans.”
As well as the burning of fossil fuels and other climate-causing human activities such as deforestation, the temperature records in 2023 were also boosted by the El Nino weather phenomenon. This warms the surface waters in the eastern Pacific Ocean and contributes to higher global temperatures. What’s in store for 2024?
Wildfire in Canada , smoke in NYC , heat domes in Texas , massive heat in the Atlantic ocean are just some of this month’s news. The world’s scientists warn of massive disruption to the planet in report after report. The leading edge of that disruption is already here.
The report states that a warming climate does not just impact temperatures but other settled weather patterns in different regions such as changes to wetness and dryness, to winds, snow and ice, coastal areas and oceans. What’s to come. In some cities, the risks of heatwaves and serious flooding will increase.
Industrial food systems are responsible for one-third of greenhouse gas emissions and are a key driver of deforestation and biodiversity loss , threatening more than 85 percent of the 28,000 species at risk of extinction.

There are many forms of carbon capture, including nature-based (in trees, soil, wetlands, ocean, regenerative agriculture, etc.), Here’s Part 1 and Part 2 ). Second, we need to describe what is included in the concept of carbon capture (also referred to as carbon capture and storage and carbon capture, utilization, and storage).
If you ever read the ingredient list on your pet’s favorite food, you may come across ambiguous terms such as ‘fish’, ‘ocean fish’, or ‘white bait’. DNA barcoding identifies endangered shark species secretly added to pet food. Have you ever wondered what exactly these ingredients are?
Ocean Conservancy’s International Coastal Cleanup ® (ICC) engages volunteers to clean up waterways around the world. The rich mangrove forest here is considered to be the city’s lungs and is in need of protection from issues like deforestation, coastal erosion and plastic pollution.
The changes to the world's oceans include warming, more frequent marine heatwaves, ocean acidification, and reduced oxygen levels. Sea levels will continue to rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas along coasts around the world.
The report, issued in conjunction with EAT Forum, also called for curbing food waste, a major source of greenhouse gas emissions, and improving agriculture so it lessens deforestation and reduces water use. Fish farming is one way suppliers to keep up with the demand without overfishing the oceans. Courtesy Anne Sprat/Unsplash.
According to Johan Rockström , a researcher with the Potsdam Institute for Climate Impact Research, offsets can be used to restore and grow new forests, protect the oceans and improve agricultural practices to increase soil health.
Fossil fuel extraction not only ignites climate change, but degrades land and wildlife ecosystems, pollutes waterways, acidifies the oceans, exacerbates natural disasters, expropriates Indigenous land , and leads to devastating chronic health impacts for fossil fuel industry workers and adjacent communities.
Deforestation is one. Our ecosystems’ ability to deal with carbon and absorb it (notably our oceans) may also be decreasing… So what should Mankind do ? As both Scientific American and the Wahington Post point out, this can be explained by the fact that carbon dioxide stays for a long time in the atmosphere.
Second, it doesn’t address the plastic pollution that is cursing our oceans. A study have found out that if we continue on current trends, we could end up with oceans having more plastic than fish by mid-century. Fails to address climate change. We, mere human, can not and should not rely on such fixes. Misses plastic pollution.
The Amazon Rainforest is home to the longest river on Earth that originates high in the Andes mountains as glacial melt and then crosses the entire continent to drain into the Atlantic Ocean. Unfortunately, the southern Amazon Rainforest is also at the center of the region’s deforestation. Lukas Musher/ANS.
The winds pick up Saharan dust, which then travels across the Atlantic Ocean to where it is deposited in the Amazon basin [4]. African biomass burning is a substantial source of phosphorus deposition to the Amazon, Tropical Atlantic Ocean, and Southern Ocean. Shukman, D. Sanchez, P. Bandy, D. Popendorf, K. Oehlert, A.
In particular, he said, “reliance upon coal, on the other hand, could aggravate the ‘greenhouse effect,’ whereby excess carbon dioxide (which accompanies coal burning) traps heat inside the earth’s atmosphere, thus possibly melting the icecaps and raising the level of the oceans.”
Additionally the continuation and the increasing deforestation rates globally which releases CO2 from the atmosphere, the failure to switch to less intensive farming methods and the limits of the oceans to store CO2 makes the challenges an uphill struggle.
SIDS face a range of risks, including extreme floods, storms, droughts, unpredictability of precipitation patterns and sea-level rise, ocean acidification and deoxygenation (World Health Organization, 2018; Douglas & Cooper, 2020, Thomas, 2020). Small Islands, Large Oceans: Voices on the Frontlines of Climate Change.
We are seeing the consequences in bushfires, acidifying oceans and locust invasions – which could push millions of people in East Africa into hunger. Keeping wild spaces wild, stopping deforestation and restoring degraded land to protect biodiversity, boost food production and store carbon. Making agriculture biodiversity positive.
From the ocean oscillations to trade winds, pressure systems that drives temperature, airborne particles that influence local conditions and even the phases of the moon and Earth's wobble all affect the climate (1). The east of the ocean is colder than normal while the west is warmer than average. Deforestation.
Tori Cress, Communications Manager at Keepers of the Water: “For Indigenous Peoples, banks’ investment in tar sands development means funding climate chaos, displacement, deforestation, poisonous water, toxic tailings, cancer, criminalization, and the further colonization of our bodies, minds, and homelands.
Acidification : Reducing the pH rating of a substance making it more acidic in nature, for example, increased carbon emissions lead to the oceans absorbing more of it, increasing acidification and damaging ecology such as coral bleaching. Dilution of salts in our oceans can affect the ecological balance of that ocean.
Deforestation and forest fragmentation are making it harder for species to move in response to climate chnage. Some marine species also experience boundaries to movement, including ocean currents, thermoclines, and shipping lanes, but they are generally more able to track changes in sea temperatures.

World leaders on Monday last week hailed a major breakthrough when, on the first official day of COP26 , a deal was agreed to stop deforestation by 2030. trillion of global assets – including Aviva, Schroders and Axa – will also commit to eliminating investment in activities linked to deforestation. Enabling deforestation.
The unrelenting heat has caused a dizzying number of air and ocean temperature records to be broken in recent weeks. As the climate continues to change due to human activities, oceans have absorbed over 90% of the excess heat. Ocean temperatures off the coast of Florida have reached as high as 97°F in recent days.
An end to deforestation would protect ecosystems from drought and wildfire, as dense vegetation can absorb and retain moisture. As the worlds most important land-based carbon sink, the Amazon is crucial for the stability of the global climate.
The British think-tank Sandbag claimed the deforestation induced by wood’s high demand will cancel out the benefit of not burning coal, thus boosting climate change rather than mitigating it. Since then, gallons of water flowed under the bridge and the H 2 O-derived renewable energy evolved into two major outputs: hydropower and ocean energy.
The increasing concentration of these gases is undoubtedly due to human activities, including the combustion of fossil fuels, industrial processes, deforestation, and destructive agricultural practices. In the oceans, CO 2 is absorbed or emitted to remain in equilibrium with carbon concentrations in the atmosphere.
Devastating forest fires, record-breaking carbon emissions, and the warmest ocean temperatures on record are just a few of the issues we’ve seen escalate, alongside rising deforestation, pollution, and plastic production. Dr Markram added, “In recent years, the world has been faced with a global pandemic of unprecedented scale.
Global deforestation pledge will be missed without urgent action, say researchers – The Guardian. NOAA – Public Comment of the Interagency Working Group on Ocean Acidification (IWG-OA). White House OSTP – Ocean Climate Action Plan. Energy agency: CO2 emissions rise in 2022, but more slowly – Associated Press.
The Indian Ocean is a hotbed of rainwater during monsoon season but the Gobi sees none of it. Its continued expansion has been put down to increased carbon emissions, agricultural activity and deforestation. It's creation as a desert is largely one of unfortunate topography; it's formed by something called “rain shadow” (40).
Nonprofit organizations and private landowners have stepped up in recent decades to combat deforestation. Poor returns again this year — chinook spend one to five years in the ocean, before returning to freshwater rivers to spawn — forced officials to apply a heavy hand. million people, Mongabay reports.
Unlike many other works of botany from that age and later, Sylva highlighted the growing problem of deforestation in England. Oceans and seas cover around 2/3 of our planet. It's a natural resource and an economic one; many problems blight our oceans today, not least of all overfishing and the dumping of waste.
We have seen governments and companies make time-bound commitments to end deforestation, restore degraded forest landscapes, and achieve sustainable forest management. But rapid deforestation and forest degradation have continued, driven primarily by growing global demand for food, fuel, and fiber.
Plaintiffs aim to hold the federal government accountable for worsening the dangers of climate change through increased reliance on fossil fuels and for breach of its fiduciary obligation to protect the atmosphere and oceans under the public trust doctrine. It has also inspired landmark decisions in climate protection on a global scale.
