Global Warming Climate Change Map – This map shows the global change in a measure called “fire risk index” (FWI) predicted by the study’s analysis for the year 2045 (red: greater extreme fire climate; blue: less) . FWI captures a combination of conditions, including low precipitation and strong winds, that together increase a region’s extreme fire weather condition.

Global Warming Climate Change Map
If global temperatures continue to rise and reach 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels, people around the world could face multiple impacts of change simultaneously. This is according to a study led by NASA that analyzed the projected impacts of such warming to understand how they could combine different effects. An increase of 2 degrees in the global temperature is considered a critical threshold above which dangerous and cascading effects of human-generated change occur.

The researchers found that more than a quarter of the world’s population could experience an additional month of severe heat stress per year compared to the middle of the 20th century (1950-1979). High temperatures and drought could combine dangerously in places like the Amazon, increasing the risk of wildfires. In the American West, extreme fire weather will likely be more intense and last longer.
To investigate the potentially compounding effects of rising temperatures, the authors of the study worked with a set of specially developed forecasts. The forecasts were originally generated by 35 of the world’s leading models – specifically, contributors to the Coupled Model Intercomparison Project (CMIP), which includes models developed by NASA’s Goddard Institute for Space Studies. CMIP provides projections that help the Intergovernmental Panel on Change and other international and national groups understand historical, current and future changes.
NASA Earth Exchange (NEX) researchers took the output from the CMIP6 models and used advanced statistical techniques to “scale” them, improving the resolution significantly. NEX uses supercomputers at NASA’s Ames Research Center in California’s Silicon Valley to analyze large amounts of data collected by aircraft and satellites or, in this case, projections produced by models. The resulting NEX dataset supporting this research is publicly available and can be found online.
With the new dataset in hand, NEX researchers in Ames analyzed the reduced projections to assess expected changes for six key variables. They examined changes in air temperature, precipitation, relative humidity, short- and long-wave solar radiation, and wind speed at a point when heat passes 2°C.
Scenario: Climate Change
“We wanted to study how these aspects of the environment are projected to change and what their combined impacts could mean for people around the world,” said Taejin Park, first author of the paper and a researcher in Ames with the Institute of Bay Area Environmental Research. (BAERI).
The researchers paid particular attention to two indicators: heat stress – or the combined effects of temperature and humidity on the human body – and fire time – which takes into account temperature, precipitation, humidity and wind. Most regions of the world will experience higher heat stress, they found, while countries closer to the equator will suffer from a greater number of days considered extreme.
“The cumulative impact of all the extremes studied could cause significant damage to communities and economies, from fires, floods, landslides, and crop failures that may result,” said Ramakrishna Nemani, senior scientist at BAERI and co-author of the study
The NEX downscaled dataset used for this research provides global, daily projections, derived from CMIP6 models, out to the year 2100. The diurnal nature of the NEX product is important to capture the extremes. If it is combined into a monthly average, Park explained, a few days projected to be dangerously hot and humid could be lost in the numbers, hiding the risk to human life.
These 7 Countries Are Responsible For Over 60 Percent Of Global Warming
The level of local and regional detail—the resolution of the projections—is higher in the NEX product than most projections, which could help managers develop adaptation and mitigation plans. The raw model projects typically yield results for areas of about 120 by 120 miles (200 by 200 kilometers), while the NEX downscaling job increases that resolution to about 15 by 15 miles (25 by 25 kilometers).
Crunching this amount of data is a big job, and the NEX researchers rely on NASA’s powerful Pleiades supercomputer in Ames. Pleiades helps solve some of NASA’s most challenging problems, playing an important role in rocket launches for the Artemis program, fuel-efficient aircraft designs, and Earth studies.
NEX scientists hope that the reduced projections could help decision makers prepare and protect their regions against the impacts. For example, a local policymaker could decide to build more flood barriers or pursue less development in flood-prone areas, said Ian Brosnan, co-author of the paper and principal scientist at NEX. The NEX dataset can also help new commercial and non-. for-profit companies develop custom risk assessments for the private and public sector.
“The reduced NASA data is in really accessible form,” Brosnan said. “People anywhere with some technical ability—from high school students to experienced scientists—can dig into the information these projections contain.”

Members of the media interested in covering these topics should contact NASA’s Ames newsroom. Scientists and politicians all agree – climate change and global warming are not just myths. They are a fact. This compilation of maps will show you what are the reasons behind this and what are the consequences of this process.
China overtook the United States as the world’s largest emitter in 2006. While emissions in Europe and the United States have fallen substantially, China is still seeing huge double-digit increases.
Countries around the world are trying to control their greenhouse gas emissions. However, to make it work, everyone needs to be on board.
Global Warming Is Happening
Cool visualization from NASA shows the annual cycle of CO2 emissions around the Earth. The study shows that most CO2 emissions are generated in the Northern Hemisphere which corresponds to the location of the most industrial centers. The gases travel around the world to be largely absorbed by the new vegetation in the spring. In winter, emissions begin to take over the planet.
Between 2000 and 2012, 2.3 million km² of forest disappeared. The greatest amount of loss has always occurred in the tropics accounting for 32% of all losses. While in Brazil, due to political efforts, the rate of loss is slightly reduced (but after 2012 the restrictions on deforestation were relaxed again), the deforestation rate in Indonesia doubled after 2003 from 10,000 km² more than 20,000 km² of forest cut per year.
This cool infographic combines 167 global temperature maps — one for each year from 1850 to 2016 — into a single chart. Blue means cooler temperatures (relative to a 1961-1990 reference period) and reds warmer. If a cell is gray, it indicates that there was not enough data to determine its color for that year.
The ice cover on the Poles and Greenland is melting rapidly. In a few years, most of Europe’s glaciers could disappear.

216 feet (66m) overall! Yes, this is the level by which sea level is expected to rise if all the ice were to melt in the oceans.
Global warming means rising sea levels, but scientists predict that it will start a chain reaction of micro and macro effects in many different areas of life on our planet. One of them is animal migration. To survive the next century, many species will have to move to cooler or more suitable habitats. This map shows the trajectories that species are expected to take over the coming decades as the climate changes.
As much as 40 percent of the world’s adult population is not aware of climate change, according to a recent study. Awareness of threats related to that process is even lower.
Waze, the crowdsourced navigation app has partnered with Esri to make it easier for Governments to access anonymized traffic information from the Waze Connected Citizens program.
Climate Change Disproportionately Affects The Arctic
The collaboration makes it easier for Governments that already use the ArcGIS platform to access traffic data from Waze to improve the transportation system, while making it easier for them to provide information on construction and road closure data to Waze. The Connected Citizen Program, a two-way data exchange, from Waze has already been adopted by more than 60 cities around the world (mainly in the USA and Europe) and the integration with ArcGIS will make it easier for Governments to use the data .
“Municipalities can now leverage real-time reporting without having to invest in sensor networks or Internet of Things infrastructure,” said Andrew Stauffer, director of civic technology at Esri. “Waze allows local governments to share open data with a purpose – in an application that is already popular with constituents, commuters and tourists.” – TechCrunch
