How Climate Change Endangers Microbes--And Why That's Not a Good Thing With another year of record-breaking warmth just over, the passage of a new climate treaty is definitely timely. But even if these new diplomatic and legislative efforts are successful the planet is ensured some amount of long-term warming—enouigh that around 8% of species are likely to go extinct due to climate change. If the warming is greater than current models project, that number could double. In all likelihood, though, those numbers are an underestimate, because there are species that no climate scientists are keeping track of. In fact, there are a lot of them, and we may come to miss them quite a bit if they disappear. There are currently no published studies of how climate change may cause extinction of microbial species. In experiments at the Harvard Forest, for example, long-term artificial warming led to reductions in both total and active microbial biomass as well as to changes in how the soil community behaved1.

Aardrijkskunde - A-stroom - Eerste graad - Secundair onderwijs - Curriculum - AKOV 1. Visie op het vak aardrijkskunde Aardrijkskunde vervult met haar fysische, sociale en economische componenten een brugfunctie tussen de natuurwetenschappelijke en de menswetenschappelijke vakken. De ruimte is op verschillende schaalniveaus het belangrijkste studie-object van de aardrijkskunde. De studie van landschappen en thema's over de hele wereld, toont de verscheidenheid aan fysische gegevens die het natuurlijk landschap beïnvloeden. Uit het voorgaande kan worden afgeleid, dat aardrijkskunde overwegend geo-ecologie is, dit is de studie van de complexe relaties tussen de mens en zijn milieu. In het streven naar een duurzame ontwikkeling kunnen vele van dergelijke polemieken worden voorkomen door een goede ruimtelijke planning. De wereld verandert voortdurend. De doelen van de aardrijkskundige vorming blijven niet beperkt tot leerinhouden. Gezien het belang dat wordt gehecht aan inzichtelijke kennis en aan waardenverheldering, ligt een leerlinggerichte aanpak voor de hand. 2. 3. 4.
Big Data Predicts Centuries Of Harm If Climate Warming Goes Unchecked The heart of NASA Center for Climate Simulation in Maryland is the "Discover" supercomputer. The software programs behind climate simulations typically have 1 million lines of code, or more.

Pat Izzo /NASA As diplomats argue in Paris over a new global agreement to fight climate change, their work is driven by scientists' dire predictions of how unchecked warming will transform our planet decades and centuries from now. But how can researchers be so sure of what will happen that far off? The Earth is big and its climate is complicated. There, in a windowless room full of what look like hulking black monoliths, thousands of linked computers crunch away on a mind-boggling number of numbers to come up with predictions about how varying amounts of greenhouse gas emissions will affect our climate's future.

Impacts of Global Warming on the Environment | UCAR - University Corporation for Atmospheric Research Findings from the 2007 IPCC report The 2007 IPCC report examined data on numerous changes to natural systems that have already been observed, as well as the potential for future impacts.

A climate that's already changing Climate is always changing, but the changes we've observed in the last several decades are best explained as a combination of natural and human-made causes. The first IPCC report, issued in 1991, discussed changes we could expect decades in the future. Some of the trends now under way—such as warmer nights during heat waves and heavier bursts of rain and snow—are expected to continue.
