Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. But what exactly would cause the AMOC to collapse?
The IPCC compiles scientific insights on climatechange, informing policymakers and the public about risks and possible actions. In essence, combined with climate models, they provide a way to envision the consequences of different actions or inactions. What Are Future Climate Scenarios?
With each successive rulemaking, EPA acknowledged that the evidence of endangerment had grown stronger over time due to the increasing severity of climatechange, new observational evidence of climate impacts, and advances in scientific understanding of how climatechange affects public health and welfare.
Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climatechange was scant. Figure SPM 8.
While temperatures provide a measure of the Earth’s climate, it is even better to use the global sealevel , which provides a far more reliable measure. The global sealevel acts like the mercury in a thermometer because warmer water expands. Our job is to be thorough and verify questionable results.
What role is climatechange playing? As climatechange increases the frequency or intensity of extreme events such as wildfires, heat waves, and heavy downpours, there is an increase in the potential for different types of risks to coincide or for a climate-related event to trigger a cascade of non-climatic consequences.
Chris Lennard from the University of Cape Town takes us through different aspects of climatechange adaptation. The good news is that there are some initiatives on climatechange adaptation which involve climate scientists such as the Infrastructure and Climate Network ( ICNet Global ).
Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room. The radiators are, in fact, cooling down, but their stored heat is still warming the air in the room.
Recent science doesn’t support this optimism, as new studies show that the increased release of Black Carbon, one of the most potent climatechange forcers—as well as soot, carbon dioxide, methane and ozone from more traffic in the Arctic—could lead to a 20% increase in the global heating that is causing warmer ocean temperatures.
” Tony DeBrum, Marshallese politician and government minister Nuclear testing spread radioactive material across the islands, in some cases causing immediate radiation poisoning, and in the long term leading to persistent health problems across generations, including cancers and reproductive issues like miscarriages and stillbirths.
A steep decline of Antarctic sea ice may mark a long-term transformation in the Southern Ocean, and seawater intrusions beneath the Thwaites Glacier could explain its melting outpacing projections.
This new, passive radar system could offer a cheaper, lower power and more easily scalable method to gather long-term data on the melting of ice sheets and glaciers due to climatechange, say the researchers. One is that the level of solar radiation is relatively low, especially at the Earth’s poles.
The International Tribunal for the Law of the Sea (ITLOS) issued an advisory opinion on April 21, 2024 in response to a request submitted by the Commission of Small Island States on ClimateChange and International Law (COSIS). 52-54) and acknowledged the critical role the ocean plays in regulating the climate system (para.
We’re already experiencing the impact of climatechange across the world; now an update from the IPCC suggests weather extremes could become the norm in the near future. The Intergovernmental Panel on ClimateChange (IPCC) is the United Nations body for assessing the science related to climatechange.
Rising sealevels and increased intensity of storm surges are playing a considerable role in the degradation of coastal regions in the Pacific Islands. Illustrating the variation in sealevels from 1993 – 2018. Pacific ClimateChange’ accessed 28 February 2021, [link]. [3] Photo credit. should be. [4]
The Altiplano plateau in western Bolivia has some of the world’s highest and most consistent levels of solar radiation, creating a high potential for solar photovoltaic power in the region, but structural challenges may prevent scaling. Photo credit: Anyisa / Alamy. By Santiago Espinoza. More small plants and storage. Not enough.”.
For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. The danger is that the Antarctic sea ice is starting to behave like the Arctic, with sustained loss of ocean cover and consequent absorption of solar radiation.
But since it became clear that human actions are damaging the environment and changing the climate, it has become much more prominent nationally and internationally with most government departments in most countries having responsibilities to mitigate or prepare for climatechange scenario. The Human Impacts on Climate.
Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone. Climatechange : The process by which the climatechanges due to “forcings”.
Despite promising adaptation strategies, sealevel rise is projected to drown tens of thousands of acres of farmland within the century. Atlantic sealevels are rising three to four times faster than the global ocean average. Crop damage radiates inward gradually from the edges of a field, where the salt hits first.
Albedo The amount of solar radiation reflected from an object or surface, often expressed as a percentage. Carbon Dioxide A naturally occurring gas, and also a byproduct of burning fossil fuels and biomass, as well as land-use changes and other industrial processes. compressed natural gas, solar, hydroelectric, wind).

Some of the impacts of climatechange are playing out faster and with a greater magnitude than we predicted.”. While we still have those things, the facts show that climatechange has transformed the months of May through October into what we are calling the Danger Season. Those impacts do not affect everyone equally.

The full Committee also approved amendments adding solar radiation management and wildfire science to the list of climatechange research topics funded by the bill. The Marine Mammal ClimateChange Protection Act ( H.R. More News: Lawmakers launch Republicans-only climatechange caucus – NBC News.
So, the main one I suppose that caught my attention was “ClimateChange is Not Making Natural Disasters” and everywhere I look, trying to approach it from your perspective, I just find it a confounding thing for you to assert. I'm not to some extent related to anthropogenic climatechange. So let's go to that.
