The Climate Case Study You’ll Never Forget
The Climate Case Study You’ll Never Forget focuses on how our planet’s climate is changing, and how these changes have had significant impacts on the way we live our lives. From our food to our air and water, from our infrastructure to our ecosystems, the impacts of climate change are now a reality that we cannot afford to ignore. These impacts will cost us billions of dollars and could have a major impact on our society and our ecosystems.
Land areas have warmed twice as much as the sea surface
The land-sea temperature contrast is a topic of interest in the climate world. It is a key factor in shaping the future of global warming.
Enhanced warming over land is not an overnight phenomenon. Instead, it is a relatively robust feature of modern climate models. A look at the temperature anomalies of the past few decades suggests that the land/sea temperature difference has been increasing faster than the oceans. Consequently, it is likely that the land/sea temperature ratio will continue to increase in the coming years.
There are several ways to measure the land-sea temperature contrast. One is to look at the difference in latent heat flux. If the average lapse rate of the land is decreasing, it is likely that the land-sea temperature difference will increase. Other measures such as precipitation and clouds could also be responsible.
A larger-scale study has found that the most important factor in the land-sea temperature contrast is the amount of water evaporation. This is a result of the aforementioned ITCZ.
Extreme weather events have racked up a large bill
What is the cost of extreme weather events and how much do Americans have to pay? Well, according to a report from NOAA (National Oceanic and Atmospheric Administration) the answer is a tad more than $1 billion per year. And the cost has been on the rise.
One interesting tidbit is that the largest number of disasters is not limited to the Atlantic and Pacific. In fact, the entire continental US saw its share of calamity this year. Among the 20 weather disasters that caused a measurable amount of damage was a winter storm in Texas which crippled the power grid. Another notable occurrence was a hurricane in Louisiana. The cost of the aforementioned event was a shade over $125bn.
While the cost of a single weather event can be prohibitive, the cumulative cost of several such incidents is nothing to sneeze at. A study by the Congressional Budget Office found that federal spending on hurricane disaster relief is growing.
Cost of warming will be $69 trillion by 2100
The cost of warming is now estimated to be $69 trillion by 2100, according to a new study by consulting firm Moody’s Analytics. This figure is nearly twice the total amount of global annual income today.
According to the report, the impacts of climate change will be felt throughout the world. It will harm human health and productivity, and disrupt infrastructure. The report also highlights the impact on tourism.
The damage costs of global warming are hard to estimate. There are many variables, such as how much carbon is emitted, how much the temperature changes, and how positive feedbacks play into the cost. A study by the UN’s Intergovernmental Panel on Climate Change (IPCC) estimates that 1.5 degrees Celsius of warming will cause $54 trillion of damages by 2100.
As the world warms, it will be harder to grow crops and livestock, which will reduce yields. In addition, warmer weather will aid the spread of vector-borne diseases.
Impacts on society and ecosystems
Climate change is altering the structure and function of Earth’s ecosystems and society. These changes affect wildlife, human health, and the economy. They also are disrupting our ability to provide critical ecosystem services.
Among the ecosystems most affected by climate change are fresh waters. Freshwaters cover 0.8 percent of the Earth’s surface, yet they are heavily exploited by humans. The rapid rate of warming is threatening these important environments.
Climate change affects many aspects of the ecology of freshwaters, including the water supply, food security, and ecosystem health. A number of studies have investigated how climate change may impact these environments. Some of the results have shown that changes in the ecological processes of freshwaters can significantly increase the risk of flooding, eutrophication, and high-intensity surface fires.
Changes in climate can also increase the risk of invasive species. One example is a non-native bryozoan species that expanded native nudibranchs in the Gulf of Maine. This is caused by an increase in nutrients and rising temperatures.
