Climate models project an increase in summer weather persistence for the northern mid-latitudes. Article 19 August There are large uncertainties in wind-wave climate projections that need to be resolved to allow adaptation planning. Letter 12 August Climate change will increase meltwater and iceberg discharge from Antarctica, with implications for future climate and sea levels. Iceberg melt will partly offset greenhouse warming in the Southern Ocean and dampen the positive feedback loop between ice-sheet melting and subsurface warming.
Additional electricity generation is required to compensate for losses from inefficient transmission and distribution infrastructure. In this study, emissions from compensatory generation and the potential for reductions are estimated for countries. Article 12 August Two independent methods, applied to observations and climate models, suggest that changes in atmospheric circulation drive cold winters in mid-latitudes and coincident mild Arctic winters. Reduced Arctic sea ice causes Arctic warming but has minimal influence on the severity of mid-latitude winters.
Author Correction 12 August Elevated CO 2 increases plant biomass, providing a negative feedback on global warming. Nutrient availability was found to drive the magnitude of this effect for the majority of vegetation globally, and analyses indicated that CO 2 will continue to fertilize plant growth in the next century.
Article 05 August Satellite altimetry shows global mean sea-level rise acceleration; however, sparse tide-gauge data limit understanding of the longer-term trend. A hybrid method of reconstruction for — shows acceleration since the s, linked to increases and shifts in Southern Hemisphere westerly winds. Publisher Correction 05 August Author Correction 02 August Letter 26 July Lack of information is a barrier to climate change adaptation, and filling the information gap is a key component of adaptation projects.
However, using a randomized controlled trial, this study finds no impact of a capacity-building workshop on community water management practices in Costa Rica. Letter 22 July Projections of temperature often focus on maximum warming levels, with variability less often considered.

Investigating decadal variability in models shows those with higher equilibrium climate sensitivity also have a higher chance of super warming, and hiatus periods. Exposure to dangerous heat following a major tropical cyclone is possible along coastlines globally. In a warmer world, the population at risk from this combination of extreme weather could rise markedly. Letter 15 July Island species are at risk as the climate changes. Island conifers are used as a model species and a combination of native and non-native occurrence data allows identification of realized, tolerable and fundamental niches; linking to island size provides an estimate of extinction risk.
Letter 08 July Physically connected habitats are required for terrestrial species to shift their liveable ranges as the tropics warm. The authors show that over half of tropical forest area is currently unable to provide such climate connectivity, and that loss of connectivity is accelerating with deforestation. Die-offs are projected to double by and quadruple by in north temperate lakes. Perspective 08 July This Perspective describes persecution, protection and ignorance archetypes for managing and monitoring species redistribution under climate change, and argues for global shared governance agreements to cope with species shifts into new geopolitical areas.
Letter 01 July Bird numbers are declining globally, with sharp decreases in alpine and Arctic regions. Increases in primary productivity in the Arctic known as greening are linked to increased nest predation, highlighting how changing climate conditions can affect food web dynamics. Observations of feeding interactions show that warming simplifies the structure of food webs in stream ecosystems.
Simulations show that consumer diversity and changes in abundance drive this simplification and can reduce ecosystem stability. This study uses spatially explicit simulations of a simple coral reef ecosystem to show that evolutionary responses to shifting environmental conditions fundamentally change effective conservation management strategies.
The length of the dry season over tropical forests is a determining factor of ecosystem health and drought risk. Hydroclimate and vegetation data show that dry season length has increased over the Congo rainforest since the s, owing to both an earlier dry season onset and a delayed end. To limit warming, a rapid reduction in coal use is needed. Early retirement of coal power plants by members of the Powering Past Coal Alliance, which includes mainly wealthy countries that use little coal, would have a modest climate impact.
Prospects for expanding the Alliance are examined.
Article 24 June Highly mobile taxa, like birds, occupy ecosystems that lack fixed boundaries, and tracking how these spatial regimes respond to environmental change is difficult. Record-breaking temperatures, humidity, and sea level rise, along with many other indicators, show that the Earth is warming fast, and that all the heat-trapping emissions we release into the atmosphere from burning fossil fuels is changing our climate.
The time to act is now. But, many powerful industry interests have hindered action and have, largely through surrogates , spread dangerous myths about climate change.

One of the preferred tactics these groups use to sow confusion is to promote studies that either ignore or misrepresent the evidence of thousands of articles published in well-established and well-respected scientific journals, which show that global warming is happening and that it is caused by humans. Scientists worldwide agree that global warming is happening, and that human activity causes it. Human influence on the climate system is clear, and recent anthropogenic emissions of green-house gases are the highest in history.
The scientific consensus is clear. Building on two previous studies , a landmark peer-reviewed study evaluated 10, scientists to confirm that over 97 percent climate scientists agree, and over 97 percent of scientific articles find that global warming is real and largely caused by humans. A more recent peer-reviewed paper examined existing studies on consensus in climate research, and concluded that the 97 percent estimate is robust.
This level of consensus is equivalent to the level of agreement among scientists that smoking causes cancer — a statement that very few people, if any, contest today.
The American public also increasingly agrees that global warming is happening. A poll from Yale found that 70 percent of Americans believe global warming is happening, while record low number of Americans 12 percent say the opposite. The acceptance of human-caused emissions as the cause of warming is not keeping pace with those that believe it is happening, but it is at 53 percent.
There is no shortage of published research on the consensus of climate scientists and climate science when it comes to human-caused global warming. In addition to the references above, you can read about how the discussion on consensus developed over time in these studies.
Many different scientific societies in the United States and numerous national academies of science from around the world have also issued statements that verify the scientific claims about human-caused warming see below. Therefore, when it comes to scientific consensus on global warming, it is important to clarify what type of uncertainty exists, and what type does not: there is strong certainty on the types of impacts that global warming is causing or would be likely to cause under a given scenario for emissions , but less certainty on the exact timing and intensity of these impacts.
For instance, on the issue of sea level rise, we know with certainty that it will happen — it is already happening — and projections under different scenarios give us a range of possible rise. But if we significantly reduce emissions, the rise will be closer to the lower levels of projections. Thankfully through time we have developed new technology to reduce the effect of global warming. However since we have dealt with global warming for so long for many years, we have double these.

Panto English 12 December Believe it or Not, Global Warming Many people believe that global warming is a hoax, whereas others claim global warming is a real phenomenon. Global warming is an increase in temperature on our planet Earth, in the water and on land. We are experiencing an increase of temperature as a result of greenhouse gases in the atmosphere because of human activities.
Scientific research is proving that since the Industrial Revolution began, human. Greenhouse gases are gases that trap heat in the atmosphere. However since there is so much carbon dioxide filling the air the Earth atmosphere absorbs almost all of the suns emission. When the sun heats the earth the atmosphere.

So, what exactly is global warming? Has it happened before? If so, what were the effects? Specifically, how will it affect the human population? Are humans causing it? These are but a few of the questions we need to answer when we study global warming. Global warming is the escalation in the average temperature of Earth's near-surface air and oceans that has been occurring since the middle of the twentieth century and its anticipated perpetuation.
