Current studies include the exploration of Arctic deep - sea life under the ice, and the long - term observation of the effects of global warming on polar ecosystems as well as on hypoxic aquatic ecosystems.

We can write down a simple recipe for the GHE, but it is indeed challenging to reconcile a presence of a negative feedback with our observations, or explain the current observed global warming in any other terms.

Once we have used real observations to understand the probability in the historical record, then we can use climate models to compare the probability in the current climate (in which global warming has occurred) with a climate in which there was no human - caused global warming.

First of all probably the biggest climate news of 2017 comes not from the scientific literature (is therefore not featured in the Royal Society report), but from direct global observations: based on preliminary data the current year is likely to rank among the three hottest years on the global record — including 2015 (2nd) and 2016 (1st), with 2014 ranking 4th.

When «Climategate» first broke, I noted the skeptic preoccupation with one tiny piece of climate science while neglecting the full weight of direct observations of current global warming.

It was the fourth in a series of conferences with the stated purpose of bringing together researchers «with varied interpretations of current and past global and regional climate change, to present the latest research results (observations, modeling and analysis), and to provide speaking and listening opportunities to top climate experts and students.»

We consider several important climate impacts and use evidence from current observations to assess the effect of 0.8 °C warming and paleoclimate data for the effect of larger warming, especially the Eemian period, which had global mean temperature about +2 °C relative to pre-industrial time.

In Phase II of AeroCom, a large - scale model intercomparison was performed to document the current state of OA modeling in the global troposphere, evaluate the OA simulations by comparison with observations, identify weaknesses that still exist in models, explain the agreements and disagreements between models and observations, and attempt to identify and analyze potential systematic biases in the models.

Compared to previous HadEX / CMIP3 - based results, which identified human contributions to the observed warming of extreme temperatures on global and regional scales, the current results provide better agreement with observations, particularly for the intensification of warm extremes.

Building on current developments in international initiatives such as the Research Data Alliance (RDA), the Belmont Forum (BF) and the Group on Earth Observations (GEO), the workshop entitled Research Data infrastructures for Environmental related Societal Challenges will be an opportunity to discuss trends of the current global landscape of e-Infrastructures for environmental data management and exploitation to enhance collaboration on a global level in support of sharing research and public sector data.

But again such global averages are of little value: regional observations should be related to the regional cloud coverage and albedo and possibly to changes of the strength of surface currents.

If there were global temperatures more than 2 °C of 3 °C above the current average temperature, this would take the climate outside of the range of observations which have been made over the last several hundred thousand years.»

the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global - scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century, owing to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice.

More generally, Pouillet's experimental prowess reminds us today that the current theory of global climate change does not rest upon mere theory only, but upon myriad observations, carried out with care, skill, and ingenuity — including a certain series made on those sunny afternoons in 1837 and 1838.
