Climate classifications are systems that categorize the world's climates. A climate classification may correlate closely with a biome classification, as climate is a major influence on life in a region. One of the most used is the Kppen climate classification scheme first developed in 1899.[21]

There are several ways to classify climates into similar regimes. Originally, climes were defined in Ancient Greece to describe the weather depending upon a location's latitude. Modern climate classification methods can be broadly divided into genetic methods, which focus on the causes of climate, and empiric methods, which focus on the effects of climate. Examples of genetic classification include methods based on the relative frequency of different air mass types or locations within synoptic weather disturbances. Examples of empiric classifications include climate zones defined by plant hardiness,[22] evapotranspiration,[23] or more generally the Kppen climate classification which was originally designed to identify the climates associated with certain biomes. A common shortcoming of these classification schemes is that they produce distinct boundaries between the zones they define, rather than the gradual transition of climate properties more common in nature.

Climate change is the variation in global or regional climates over time.[33] It reflects changes in the variability or average state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces (e.g. variations in sunlight intensity) or, more recently, human activities.[34][35] Scientists have identified Earth's Energy Imbalance (EEI) to be a fundamental metric of the status of global change.[36]

To date, cities and states in colder climates have focused on decarbonizing building heating systems by promoting high efficiency gas products. But the paradigm-upending year that is 2020 has seen leading states commit to aggressive goals for migrating away from fossil-fuel-based heating and instead toward heat pump alternatives:

But despite the clear efficiency and carbon benefits, air source heat pumps have historically been relegated to more moderate climates, such as the Southeastern United States. One reason is that models from the 1980s struggled to operate efficiently (or operate at all) in sub-freezing temperatures.

The availability of adequate testing standards represents a start, rather than a completion, of this work. Consumer and installer perceptions based on older generations of heat pump technology have built up over decades. Memories of chilly homes or unhappy customers during heating season will continue to make installers in colder climates slow to adopt heat pumps as a core offering.

By the 2080s, the climate of North American urban areas will feel substantially different, and, in many cases, completely unlike contemporary climates found anywhere in the western hemisphere north of the equator. If emissions continue unabated throughout the 21st century,the climate of North American urban areas will become, on average, most like the contemporary climate of locations about 500 miles away and mainly to the south.

Through the lens of evolution, climate change is an agent of natural selection that forces populations to change and adapt, or face extinction. However, current assessments of the risk of biodiversity associated with climate change1 do not typically take into account how natural selection influences populations differently depending on their genetic makeup2. Here we make use of the extensive genome information that is available for Arabidopsis thaliana and measure how manipulation of the amount of rainfall affected the fitness of 517 natural Arabidopsis lines that were grown in Spain and Germany. This allowed us to directly infer selection along the genome3. Natural selection was particularly strong in the hot-dry location in Spain, where 63% of lines were killed and where natural selection substantially changed the frequency of approximately 5% of all genome-wide variants. A significant portion of this climate-driven natural selection of variants was predictable from signatures of local adaptation (R2 = 29-52%), as genetic variants that were found in geographical areas with climates more similar to the experimental sites were positively selected. Field-validated predictions across the species range indicated that Mediterranean and western Siberian populations-at the edges of the environmental limits of this species-currently experience the strongest climate-driven selection. With more frequent droughts and rising temperatures in Europe4, we forecast an increase in directional natural selection moving northwards from the southern end of Europe, putting many native A. thaliana populations at evolutionary risk.

Students' perceptions of their school climates are associated with psychosocial and academic adjustment. The present study examined the role of school strategies to promote safety in predicting students' perceptions of safety for gender nonconforming peers among 1415 students in 28 high schools. Using multilevel modeling techniques, we examined student- and school-level effects on students' perceptions of safety for gender nonconforming peers. We found that older students, bisexual youth, Latino youth, and youth who experienced school violence perceived their gender nonconforming male peers to be less safe. Similarly, we found that older students and students who experienced school violence and harassment due to gender nonconformity perceived their gender nonconforming female peers to be less safe. At the school-level, we found that when schools included lesbian, gay, bisexual, transgender, and queer (LGBTQ) issues in the curriculum and had a Gay-Straight Alliance, students perceived their schools as safer for gender nonconforming male peers.

This improves the explanatory power of the State Business Tax Climate Index as a whole because components with higher standard deviations are those areas of tax law where some states have significant competitive advantages. Businesses that are comparing states for new or expanded locations must give greater emphasis to tax climates when the differences are large. On the other hand, components in which the 50 state scores are clustered together, closely distributed around the mean, are those areas of tax law where businesses are more likely to de-emphasize tax factors in their location decisions. For example, Delaware is known to have a significant advantage in sales tax competition, because its tax rate of zero attracts businesses and shoppers from all over the Mid-Atlantic region. That advantage and its drawing power increase every time another state raises its sales tax.

Reconstructions from paleoclimate archives allow current changes in atmospheric composition, sea level and climate systems (including extreme events such as droughts and floods), as well as projections of future climates, to be placed in a broader perspective of past climate variability. Past climate information also documents the behavior of slow components of the climate system including the carbon cycle, ice sheets and the deep ocean for which instrumental records are short compared to their characteristic time scales of responses to perturbations, thus informing on mechanisms of abrupt and irreversible changes. Climate records over past centuries and millennia indicate that average temperatures in recent decades over much of the world have been much higher, and have risen faster during this time period, than at any time for which the historical global distribution of surface temperatures can be reconstructed.

But not all grapes thrive in all climates. Some are better suited to cooler zones, while others prefer heat and sun. The grapes most adept to cooler regions include Riesling, Sauvignon Blanc, Pinot Gris and Gewrtztraminer for whites, and Pinot Noir and Zweigelt for reds. Zinfandel, Grenache and Shiraz are common in warmer climates.

Growers in cooler climates do face distinct challenges. Vines may be lower yielding, winters can harm or kill the vines and frost events are more common and destructive. Polar vortexes that seem to dominate the news during winter can claim entire vintages in the Finger Lakes and Ontario.

Given all the troubles endured in cooler climates, warmer temperatures should be the way to go, right? More sunshine, consistent weather and a longer fall ripening period produce wines that possess fuller body and flavors. Grapes ripen faster and accumulate more sugars, which result in higher alcohol levels during fermentation. Darker fruit flavors often dominate like plums, blueberries, blackberries, and these wines can even exhibit chocolate notes.

While the weather can change in just a few hours, climate changes over longer timeframes. Climate events, like El Nio, happen over several years, small-scale fluctuations happen over decades, and larger climate changes happen over hundreds and thousands of years. Today, climates are changing. Our Earth is warming more quickly than it has in the past according to the research of scientists. Hot summer days may be quite typical of climates in many regions of the world, but global warming is causing Earth's average global temperature to increase. The amount of solar radiation, the chemistry of the atmosphere, clouds, and the biosphere all affect Earth's climate.

Paleoclimatology is the study of past climates. Since it is not possible to go back in time to see what climates were like, scientists use imprints created during past climate, known as proxies, to interpret paleoclimate. Organisms, such as diatoms, forams, and coral serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores (which include diatoms, foraminifera, microbiota, pollen, and charcoal within the sediment and the sediment itself).

The latitude, ground, and height can change the climate of a location. It is also important to note if oceans or other large bodies of water are nearby. Climates are most commonly classified by temperature and precipitation. The most commonly used classification was the Kppen climate classification, first made by Wladimir Kppen. The Thornthwaite system,[1] which was used from 1948, not only uses temperature and precipitation information, but evapotranspiration too. This makes it useful for studying how many different kinds of animal species there are, and about the things that could happen when climates change. The Bergeron and Spatial Synoptic Classification systems focus more on where the air masses which help make climates come from. ff782bc1db
